Abstract
Turner syndrome is the most common sex chromosome abnormality in women. Infertility and short stature are the most striking findings seen in these patients. Unfortunately, many girls are still being diagnosed too late and therefore early diagnosis and treatment key. Turner syndrome affects many systems of the body; therefore, a comprehensive approach is key for therapeutic intervention.

Abstract
PURPOSE OF REVIEW Turner syndrome is the most common sex chromosome abnormality in female individuals, affecting 1/2000-1/2500 female newborns. Despite the high incidence of this condition, the mechanisms underlying the development of multiorgan dysfunction have not been elucidated. RECENT FINDINGS Clinical features involve multiple organ systems and include short stature, dysmorphic facial features, delayed puberty and gonadal failure, cardiac and renal abnormalities, audiologic abnormalities, and a high prevalence of endocrine and autoimmune disorders. Paucity of available genotype/phenotype correlation limits the ability of clinicians to provide accurate guidance and management. Given the advent of robust genetic testing and analysis platforms, developments in the genetic basis of disease are materializing at a rapid pace. SUMMARY The objective of this review is to highlight the recent advances in knowledge and to provide a framework with which to apply new data to the foundational understanding of the condition.

Abstract
Fragile X (FXS) and Turner (TS) syndromes are X-chromosome-associated disorders. Herein, we report the case of a girl in middle childhood with bicuspid aortic valve in infancy, growth failure, global developmental delay (GDD), visual problems, and coexisting attention-deficit/hyperactivity and anxiety disorders. A high-resolution karyotype in 20 cells revealed 46,X,Idic(X)(p11.21)[19]/45,X[1], suggestive of variant TS. Given her atypical phenotype, subsequent DNA testing was performed. Four FMR1 cytosine-guanine-guanine repeats (30, 410, 580 and 800) were identified, confirming the additional FXS diagnosis. This case study highlights the importance of additional genetic testing in individuals with atypical variant TS, such as unexplained GDD and distinct facial characteristics. The additional FXS diagnosis prompted new therapeutic development for the patient to advance precision healthcare.

MicroRNA-126-3p/5p and Aortic Stiffness in Patients with Turner Syndrome. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9081109.

Abstract
Background: Turner Syndrome (TS) is a relatively rare X-chromosomal disease with increased cardiovascular morbidity and mortality. This study aimed to identify whether the circulating miR-126-3p/5p are involved in the pathophysiology of vascular dysfunction in TS. Methods: Using the RT-qPCR, the abundance levels of miR-126-3p and miR-126-5p were determined in 33 TS patients and 33 age-matched healthy volunteers (HVs). Vascular screening, including the assessment of blood pressure, pulse wave velocity, augmentation index, aortic deformation, arterial distensibility, and arterial elastance, was conducted in TS patients and HVs. Results: The abundance levels of miR-126-3p and miR-126-5p were significantly higher in TS patients compared to HVs (p < 0.0001). Within the TS cohort, miR-126-3p/5p correlated significantly with aortic deformation (r = 0.47, p = 0.01; r = 0.48, p < 0.01) and arterial distensibility (r = 0.55, p < 0.01; r = 0.48, p < 0.01). In addition, a significant negative correlation was demonstrated between miR-126-3p and arterial elastance (r = −0.48, p = 0.01). The receiver operating characteristic analysis showed that miR-126-3p and miR-126-5p separated the tested groups with high sensitivity and specificity. Conclusions: The abundance levels of miR-126-3p and miR-126-5p were significantly higher in TS patients compared to HVs. Within the TS cohort, a lower abundance level of miR-126-3p and miR-126-5p was linked with a significantly higher aortic stiffness.

Abstract
Turner syndrome (TS; ORPHA 881) is a rare condition in which all or part of one X chromosome is absent from some or all cells. It affects approximately one in every 1/2500 liveborn girls. The most frequently observed karyotypes are 45,X (40–50%) and the 45,X/46,XX mosaic karyotype (15–25%). Karyotypes with an X isochromosome (45,X/46,isoXq or 45,X/46,isoXp), a Y chromosome, X ring chromosome or deletions of the X chromosome are less frequent. The objective of the French National Diagnosis and Care Protocol (PNDS; Protocole National de Diagnostic et de Soins) is to provide health professionals with information about the optimal management and care for patients, based on a critical literature review and multidisciplinary expert consensus. The PNDS, written by members of the French National Reference Center for Rare Growth and Developmental Endocrine disorders, is available from the French Health Authority website. Turner Syndrome is associated with several phenotypic conditions and a higher risk of comorbidity. The most frequently reported features are growth retardation with short adult stature and gonadal dysgenesis. TS may be associated with various congenital (heart and kidney) or acquired diseases (autoimmune thyroid disease, celiac disease, hearing loss, overweight/obesity, glucose intolerance/type 2 diabetes, dyslipidemia, cardiovascular complications and liver dysfunction). Most of the clinical traits of TS are due to the haploinsufficiency of various genes on the X chromosome, particularly those in the pseudoautosomal regions (PAR 1 and PAR 2), which normally escape the physiological process of X inactivation, although other regions may also be implicated. The management of patients with TS requires collaboration between several healthcare providers. The attending physician, in collaboration with the national care network, will ensure that the patient receives optimal care through regular follow-up and screening. The various elements of this PNDS are designed to provide such support.

Effect of Growth Hormone Treatment on the Concentration of Selected Metabolic Markers in Girls With Turner Syndrome. Front Endocrinol (Lausanne) 2022; 13:818735.

Abstract
Background As Turner syndrome (TS) predisposes to obesity and metabolic disorders, and their complications, such as cardiovascular diseases, are the main causes of shortened life expectancy in patients with TS, new metabolic markers that could serve as early predictors of dysmetabolic state are sought. Objective Assessment of MMP-1 (matrix metalloproteinase-1), MMP-2 (matrix metalloproteinase-2), MMP-9 (matrix metallopeptidase-9), BDNF (brain-derived neurotrophic factor), GDNF (glial cell line-derived neurotrophic factor), and VEGF (vascular endothelial growth factor) before the onset of growth hormone (GH) therapy and then during GH treatment as well as markers assessment during GH medication in girls with TS to establish marker stability and repeatability, and the impact of GH on markers concentration. Method The concentrations of circulating MMP-1, MMP-2, MMP-9, BDNF, GDNF, and VEGF were measured in nine girls with TS before the onset of GH therapy and then after at least 3 months of treatment period. Subsequently, markers concentration was determined in 17 girls during GH medication, with the first determination after at least a 3-month treatment period. The patients' clinical and biochemical phenotypes were determined by weight, height, BMI, total cholesterol, HDL cholesterol, triglycerides, and glucose concentration. Results Comparison of markers concentration revealed a significantly higher concentration of MMP-2 in patients undergoing GH treatment (132.1 ± 42.05) than before the onset of therapy (105.0 ± 45.5, p=0.045). The values of the first measurement of VEGF in girls with TS undergoing GH therapy were significantly higher than those during the second measurement (30.9 ± 33.4 vs. 12.5 ± 11.7, p=0.029). There were no statistically significant differences between the measurements of the remaining markers concentration at any stage of the analysis. Conclusion Increase in MMP-2 concentration is visible during GH therapy in comparison to the pre-GH period in girls with TS which demands confirmation in subsequent tests. The role of VEGF requires further studies in the context of carbohydrate-lipid disturbances in girls with TS and its association with GH treatment.

Abstract
BACKGROUND Turner syndrome is a genetic disorder that affects only females. It has specific cognitive characteristics, but speech and language data are scarce. METHODS AND PROCEDURES Prospective case report; we report a girl aged seven's cognitive and speech and language profile. RESULTS Cognitive assessment shows higher performance IQ (PIQ), and atypical cognitive profile for Turner syndrome. Speech and language assessment show a significant difference between receptive and expressive language levels. Although the girl did comprehend most of the language structure, there was a lack of it in spontaneous speech. She demonstrated inconsistency in the use of language morphology and complex linguistic structures, primarily because of significant inconsistency in her sound production. Although she produced the majority of phonemes correctly in isolation, her spontaneous speech production was incomprehensible. CONCLUSION Case studies of speech and language development may reveal a specific characteristic in the cases with Turner syndrome to delineate genetic factors from individual developmental variabilities.

Abstract
Turner Syndrome (TS) is a genetic disorder caused by total or partial loss of an X chromosome. The isochromosome X (i(X)) is a known variant of TS, however, double i(X) is a very rare variant, reported very few times in the literature. We report on a rare case of TS with double i(X). This is an 11-year-old female patient , addressed to the medical genetics consultation for short stature and facial features suggestive of TS. We performed a constitutional postnatal karyotype from a peripheral blood sample, with lymphocyte culture, and an R band analysis, performed on 70 metaphases. Metaphases analysis in our patient identified the presence of three cell populations: 45,X[22]/46,X,i(X)(q10)[30]/47,X,i(X)(q10),i(X)(q10) [18]. The first has total chromosome X monosomy, the second with a normal X chromosome and one isochromosome of the long arm of the other X chromosome and the third with a normal X chromosome and two isochromosomes of the long arm of the X chromosome. A control cell culture was performed from a second blood sample of the patient and confirmed the abnormality. This paper will discuss this case in comparison with other rare cases described, as well as the formation of the double isochromosome, based on the literature.

Abstract
PURPOSE Characterize outcomes among adolescents and young adults (AYAs) with sex chromosome disorders (SCDs) after oocyte cryopreservation (OC) consultation. METHODS Retrospective case series of all AYA (< 25 years) patients with SCDs seen for OC consultation from 2011 to 2019 at a large, urban, academic fertility center. All AYA patients with an SCD seen for OC consult in the study time period were reviewed and included. Data collected included patient age, SCD type, number of patients who attempted OC, number of cycles attempted, and cycle outcomes. RESULTS Twenty-two patients were included: 9 with Turner syndrome, 12 with mosaic Turner syndrome, and 1 with 47,XXX. Mean age at consult was 14.7 ± 3.5 years. Fourteen patients elected for OC: 5 with Turner syndrome, 8 with mosaic Turner syndrome, and 1 47,XXX who pursued 31 OC cycles total. Of those 14 patients, 10 underwent retrieval, 9 froze oocytes, and 8 froze mature (MII) oocytes. Seven patients underwent > 1 cycle and 7 had ≥ 1 cancelation. 3/3 patients who pursued cycles after 1st cancelation never got to retrieval. Age, SCD type, and baseline FSH did not predict ability to freeze MIIs. One patient returned after OC and attempted 4 ovulation induction cycles and 2 IVF cycles; all were canceled for low response. CONCLUSIONS AYA patients with SCDs have a high risk of poor response and cycle cancelation but the majority froze MIIs. Thus, setting expectations is important. A larger sample size is needed to evaluate possible clinical predictors of success.

Abstract
PURPOSE OF REVIEW There are over a million adults living with congenital heart disease (CHD) in the USA. There have been improvements in CHD management which have led to an expansion of the adult congenital heart disease (ACHD) population. There is a high prevalence of atherosclerotic cardiovascular disease (ASCVD) encountered in the aging ACHD population. This review focuses on the most recent literature regarding the primary prevention of ASCVD in young ACHD patients. RECENT FINDINGS There are unique considerations for ASCVD risk reduction in ACHD patients. ASCVD may be as prevalent in ACHD compared in the general population. However, there may be a perceived shorter life expectancy in ACHD patients; therefore, primary prevention of ASCVD may not be considered important. Preventative strategies for ASCVD are underutilized in ACHD patients. As these patients are followed for a lifetime by cardiologists, we can truly pursue primary prevention in this aging population.

Abstract
Abstract
Background
Premature ovarian failure (POF) is a complex heterogeneous disorder characterized by the triad of amenorrhea, hypergonadotropinism, and hypoestrogenism in women before the expected age of menopause. In most POF patients, the etiology is idiopathic. X chromosome abnormalities are known to be responsible for many POF cases but the effect of sex chromosome low level mosaicism on ovarian function still remains unclear. The aim of this study was to investigate the prevalence and type of cytogenetic abnormalities as well as low-level sex chromosome mosaicism in Egyptian females with POF.
Results
The present study recruited thirty women with POF and thirty women with normal reproductive history as a control group. Conventional cytogenetic analysis was carried out on POF patients in order to detect cytogenetic abnormalities. FISH on interphase and metaphase nuclei from patients with normal karyotype as well as from thirty control women with normal reproductive history was performed using X, Y, and 18 centromeric probes to evaluate low-level sex chromosome mosaicism. Conventional cytogenetic analysis of peripheral blood lymphocytes demonstrated chromosomal aberrations in 7 cases. FISH revealed that the rate of X chromosome mosaicism was significantly higher in POF patients than in the control group.
Conclusion
We concluded that X chromosome abnormalities including low level mosaicism may be underlying the pathology of POF as increased mosaicism may lead to accelerated oocyte aging and premature follicular atresia.

Abstract
Background: Loss or partial loss of one X chromosome induces Turner syndrome (TS) in females, causing major medical concerns, including otologic disorders. However, the underlying genetic pathophysiology of otologic disorders in TS is mostly unclear. Methods: Ear-related genes of TS (TSEs) were identified by analyzing differentially expressed genes (DEGs) in two Gene Expression Omnibus (GEO)-derived expression profiles and ear-genes in the Comparative Toxicogenomic Database (CTD). Subsequently, Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Disease Ontology (DO) analyses; Gene Set Enrichment Analysis (GSEA); and Gene Set Variation Analysis (GSVA) were adopted to study biological functions. Moreover, hub genes within the TSEs were identified by assessing protein-protein interaction (PPI), gene-microRNA, and gene-transcription factor (TF) networks. Drug-Gene Interaction Database (DGIdb) analysis was performed to predict molecular drugs for TS. Furthermore, three machine-learning analysis outcomes were comprehensively compared to explore optimal biomarkers of otologic disorders in TS. Finally, immune cell infiltration was analyzed. Results: The TSEs included 30 significantly upregulated genes and 14 significantly downregulated genes. Enrichment analyses suggested that TSEs play crucial roles in inflammatory responses, phospholipid and glycerolipid metabolism, transcriptional processes, and epigenetic processes, such as histone acetylation, and their importance for inner ear development. Subsequently, we described three hub genes in the PPI network and confirmed their involvement in Wnt/β-catenin signaling pathway and immune cell regulation and roles in maintaining normal auditory function. We also constructed gene-microRNA and gene-TF networks. A novel biomarker (SLC25A6) of the pathogenesis of otologic disorders in TS was identified by comprehensive comparisons of three machine-learning analyses with the best predictive performance. Potential therapeutic agents in TS were predicted using the DGIdb. Immune cell infiltration analysis showed that TSEs are related to immune-infiltrating cells. Conclusion: Overall, our findings have deepened the understanding of the pathophysiology of otologic disorders in TS and made contributions to present a promising biomarker and treatment targets for in-depth research.

Abstract
Background: This study aimed to investigate whether the cardiovascular care of Turner Syndrome (TS) women in Germany is in accordance with the latest clinical practice guidelines established by the 2016 Cincinnati international TS meeting. Methods: An anonymous online questionnaire was created to ask TS subjects about existing cardiovascular conditions and cardiovascular care received. Depending on cardiovascular morbidity and type of medical care received, the fulfillment of the latest clinical practice guidelines for the care of TS women was assessed. Results: 120 TS patients were included in this study. The mean age of TS subjects was 36.79 years. Only 80% of subjects received annual blood pressure measurements within the TS cohort, and only 60% received cardiac imaging according to international clinical practice guidelines. More than 55% of TS women did not feel well informed about TS-specific cardiovascular risk factors by their treating physician. Conclusions: A potential lack of cardiovascular care might be present in TS women in Germany as the results of this online patient survey suggest. The cardiovascular care of TS patients, particularly cardiac imaging and patient education, needs to receive more attention.

Pediatric growth hormone treatment in Italy: A systematic review of epidemiology, quality of life, treatment adherence, and economic impact. PLoS One 2022; 17:e0264403. [PMID: 35213607 PMCID: PMC8880399 DOI: 10.1371/journal.pone.0264403] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Accepted: 02/09/2022] [Indexed: 11/18/2022] Open
Abstract
Objectives This systematic review aims to describe 1) the epidemiology of the diseases indicated for treatment with growth hormone (GH) in Italy; 2) the adherence to the GH treatment in Italy and factors associated with non-adherence; 3) the economic impact of GH treatment in Italy; 4) the quality of life of patients treated with GH and their caregivers in Italy. Methods Systematic literature searches were performed in PubMed, Embase and Web of Science from January 2010 to March 2021. Literature selection process, data extraction and quality assessment were performed by two independent reviewers. Study protocol has been registered in PROSPERO (CRD42021240455). Results We included 25 studies in the qualitative synthesis. The estimated prevalence of growth hormone deficiency (GHD) was 1/4,000–10,000 in the general population of children; the prevalence of Short Stature HOmeoboX Containing gene deficiency (SHOX-D) was 1/1,000–2,000 in the general population of children; the birth prevalence of Turner syndrome was 1/2,500; the birth prevalence of Prader-Willi syndrome (PWS) was 1/15,000. Treatment adherence was suboptimal, with a range of non-adherent patients of 10–30%. The main reasons for suboptimal adherence were forgetfulness, being away from home, pain/discomfort caused by the injection. Economic studies reported a total cost for a complete multi-year course of GH treatment of almost 100,000 euros. A study showed that drug wastage can amount up to 15% of consumption, and that in some Italian regions there could be a considerable over- or under-prescribing. In general, patients and caregivers considered the GH treatment acceptable. There was a general satisfaction among patients with regard to social and school life and GH treatment outcomes, while there was a certain level of intolerance to GH treatment among adolescents. Studies on PWS patients and their caregivers showed a lower quality of life compared to the general population, and that social stigma persists. Conclusion Growth failure conditions with approved GH treatment in Italy constitute a significant burden of disease in clinical, social, and economic terms. GH treatment is generally considered acceptable by patients and caregivers. The total cost of the GH treatment is considerable; there are margins for improving efficiency, by increasing adherence, reducing drug wastage and promoting prescriptive appropriateness.

Abstract
Pollens are typically the primary reason for seasonal hypersensitivity caused in many people that are released by a hundred different species of plants for fertilization. Not all pollens are the same or have the same effect on human beings, there are those worse than others. The human body works out on a defence mechanism by creating certain reactions against those offensive pollens as a response by the immune system. The allergic reactions include sneezing, coughing, wheezing, itching, red-watery swelled eyes, runny nose, inflammation in the nasal passage frequently leading to rhinitis, asthma, skin irritation, and other respiratory disorders. This study is intended to acquire knowledge about a few plants with high allergenic properties along with their major allergens. It is evident that the pollination of the plants varies from season to season as it depends on various factors such as species, weather, and geographical location. Understanding these high allergenic plants with respect to their varying factors and cross-reacting properties is the purpose of this study. It is an effort to obtain deeper insights into these common pollen offenders.

Abstract
Noonan, Turner, and Prader-Willi syndromes are classical genetic disorders that are marked by short stature. Each disorder has been recognized for several decades and is backed by extensive published literature describing its features, genetic origins, and optimal treatment strategies. These disorders are accompanied by a multitude of comorbidities, including cardiovascular issues, endocrinopathies, and infertility. Diagnostic delays, syndrome-associated comorbidities, and inefficient communication among the members of a patient's health care team can affect a patient's well-being from birth through adulthood. Insufficient information is available to help patients and their multidisciplinary team of providers transition from pediatric to adult health care systems. The aim of this review is to summarize the clinical features and genetics associated with each syndrome, describe best practices for diagnosis and treatment, and emphasize the importance of multidisciplinary teams and appropriate care plans for the pediatric to adult health care transition.

Abstract
Purpose This study evaluated the reproductive potential of premature ovarian insufficiency (POI) patients with abnormal karyotypes undergoing infertility treatments. Methods A retrospective analysis of infertility treatments in POI patients with an abnormal karyotype treatment. Clinical and laboratory data were analyzed. Results The study group was forty‐nine POI patients. Follicular growth was achieved in 29% (89/307) controlled ovarian stimulation (COS) cycles in 57% (28/49) of patients. Oocyte retrieval was attempted in 47% (23/49) of patients with a proportion of successful oocyte retrieval per oocyte pick‐up (OPU) of 59.4% (41/69). The average number of retrieved oocytes was 2.4 ± 2.7 per patient and fertilization rate was 70.7% (29/41). Embryo transfer (ET) performed in eight patients with a total of nine ET attempts, resulting in 33.3% (3/9) of live birth rate per ET. Three patients delivered a healthy baby (6.1% (3/49) of live birth rate per patient). Mosaic Turner syndrome patients had a longer duration of amenorrhea and lower chances of successful follicular growth with OPU in 35.7% (5/14) of patients, whereas 47XXX had shorter duration of amenorrhea and COS with follicle growth with OPU in 83.3% (5/6). Conclusion COS might provide an opportunity for POI women with abnormal karyotypes to conceive a biological offspring.

Abstract
Turner syndrome (TS) is a chromosomal disorder affecting females characterized by short stature and gonadal dysgenesis. Untreated girls with TS reportedly are approximately 20-cm shorter than normal girls within their respective populations. The growth patterns of girls with TS also differ from those of the general population. They are born a little smaller than the normal population possibly due to a mild developmental delay in the uterus. After birth, their growth velocity declines sharply until 2 years of age, then continues to decline gradually until the pubertal age of normal children and then drops drastically around the pubertal period of normal children because of the lack of a pubertal spurt. After puberty, their growth velocity increases a little because of the lack of epiphyseal closure. A secular trend in height growth has been observed in girls with TS so growth in excess of the secular trend should be used wherever available in evaluating the growth in these girls. Growth hormone (GH) has been used to accelerate growth and is known to increase adult height. Estrogen replacement treatment is also necessary for most girls with TS because of hypergonadotropic hypogonadism. Therefore, both GH therapy and estrogen replacement treatment are essential in girls with TS. An optimal treatment should be determined considering both GH treatment and age-appropriate induction of puberty. In this review, we discuss the growth in girls with TS, including overall growth, pubertal growth, the secular trend, growth-promoting treatment, and sex hormone replacement treatment.

Abstract
Congenital ptosis, a birth defects presents at birth or by 1 year of age, is characterized by the drooping of the upper eyelid. either in isolation (non-syndromic) or with many different systemic disorders (syndromic). The estimated prevalence of ptosis (congenital & acquired) ranges from 0.79 to 1.99 per 10,000 people in different populations, and it is more prevalent in males. The underlying pathogenesis of congenital ptosis are myogenic and neurogenic, related to the development of muscles and nerves. Although most cases are sporadic, there are familial transmission characteristics, including autosomal dominant, recessive mode and X-linkage inheritance patterns. Moreover, some forms are due to chromosomal aberrations and mutations and deletions in mitochondrial DNA. Genes involved in simple congenital ptosis are ZFHX4 and COL25A1. The clinical aspects of various syndromes involving congenital ptosis are partly caused by single gene mutations. However, the pathogenesis of congenital ptosis is not fully understood. We review the reported epidemiology, genetics and clinical features of congenital ptosis and associated syndromes here.

Abstract
Turner syndrome (TS) is a rare chromosomal disease with increased cardiovascular morbidity and mortality. The aim of this study was to investigate the influence of physical activity and diet quality on cardiovascular morbidity in German TS women. An anonymous online questionnaire was established. The questionnaire was based on the 2020 WHO recommendations on physical activity and sedentary behaviour and included the 14-Item Mediterranean Diet Assessment Tool. In addition, TS patients were asked about existing cardiovascular conditions. In total, 83 TS women were included in the final analysis. The achievement of <600 Metabolic Equivalent-minutes per week for recreational activities was significantly associated with the presence of arterial hypertension (p = 0.006). High adherence to the Mediterranean diet was achieved by only 20.5% of TS subjects and tended to be inversely associated with the presence of lipid metabolism disorders (p = 0.063). Only 37.3% of TS participants received nutritional counselling. Given the increased cardiovascular risk, specific counselling for lifestyle optimisation may play an important role in the management of TS. Further studies are required to evaluate the effects of regular aerobic physical training and different nutritional programs on cardiovascular morbidity in TS.

Abstract
We report a 21-year-old woman with Turner's syndrome, Graves' disease and primary hyperparathyroidism. At 12 years of age, she was of short stature, and was diagnosed with Turner's syndrome and treated with growth hormone. At the age of 17 years, she was diagnosed with Graves' disease. On treatment with methimazole, her laboratory findings normalized. At the age of 20 years, her serum calcium and intact parathyroid hormone levels were high. The upper left parathyroid gland showed swelling and was resected, and adenoma was diagnosed pathologically. Then, primary hyperparathyroidism induced by the adenoma was diagnosed. After the parathyroidectomy, the patient's serum calcium and intact parathyroid hormone levels normalized. Is likely that Turner's syndrome and Graves' disease were not associated with primary hyperparathyroidism. Multiple endocrine neoplasia type 1 was unlikely considering the clinical, laboratory, ultrasonographic, and scintigraphic findings.

Abstract
Turner syndrome (TS) is a chromosomal disorder that affects 25-50 per 100,000 live born females. Patients with TS face a heavy burden of cardiovascular disease (congenital and acquired) with an increased risk of mortality and morbidity compared to the general population. Cardiovascular diseases are a major cause of death in females with TS. Approximately 50% of TS patients have a congenital heart abnormality, with a high incidence of bicuspid aortic valve (BAV), coarctation of the aorta (CoA) and generalised arteriopathy. Frequently, females with TS have systemic hypertension, which is also a risk factor for progressive cardiac dysfunction and aortopathy. This paper aims to provide an overview of the cardiovascular assessment, management and follow up strategies in this high-risk population of TS patients.

Recombinant growth hormone therapy in children with Turner Syndrome in Korea: a phase III Randomized Trial. BMC Endocr Disord 2021; 21:243. [PMID: 34893062 PMCID: PMC8662840 DOI: 10.1186/s12902-021-00904-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2021] [Accepted: 11/12/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Short stature is the most consistent characteristic feature of Turner syndrome (TS). To improve final heights of children with TS effectively, it is important to provide them with early and appropriate treatment using growth hormone (GH). The objective of this study was to assess the efficacy and safety of a new recombinant human GH, Growtropin®-II (DA-3002, Dong-A ST Co., Ltd) versus a comparator (Genotropin®, Pfizer Inc.) for Korean children with TS. METHODS This open-label, active-controlled, parallel-group, randomized controlled phase III trial was conducted at 11 hospitals in Korea. Eligible patients (n = 58) were randomized to two groups: 1) DA-3002 group (administrated with DA-3002 at 0.14 IU [0.0450-0.050 mg] /kg/day); and 2) comparator group (administrated with the comparator at 0.14 IU [0.0450-0.050 mg] /kg/day). RESULTS The change from baseline in annualized height velocity (HV) after a 52-week treatment period was 4.15 ± 0.30 cm/year in the DA-3002 group and 4.34 ± 0.29 cm/year in the comparator group. The lower bound of 95% two-sided confidence interval for group difference in the change of annualized HV (- 1.02) satisfied the non-inferiority margin (- 1.5). The change in height standard deviation score (HtSDS) at 52-week was 0.70 ± 0.23 for the DA-3002 group and 0.66 ± 0.39 for the comparator group, showing no significant (p = 0.685) difference between the two groups. The change of skeletal maturity defined as change in bone age/change in chronological age between the two groups was not significantly different (1.25 ± 0.58 for the DA-3002 group and 1.47 ± 0.45 for the comparator group, p = 0.134). Changes from baseline in serum insulin-like growth factor-1 (IGF-1) and insulin-like growth factor binding protein-3 (IGFBP-3) after 52 weeks of treatment did not differ significantly between the two groups (p = 0.565 and p = 0.388, respectively) either. The occurrence of adverse events was not statistically different between groups. CONCLUSIONS This study demonstrates that the efficacy and safety of GH treatment with DA-3002 in children with TS are comparable with those of the comparator. It is expected to analysis the long-term effect of DA-3002 on the increase of final adult height in children with TS and possible late-onset complications in the future. TRIAL REGISTRATION The study was registered at ClinicalTrials.gov. ClinicalTrials.gov identifier: NCT01813630 (19/03/2013).

Abstract
Primary amenorrhea is a serious medical condition. A thorough clinical assessment is necessary for a timely and correct diagnosis and management of this ailment to prevent long-term health and social problems. Turner's syndrome is considered one of the important causes of primary amenorrhea, with an incidence of one in 2,500 to one in 3,000 live-born girls. In this report, we present an interesting case involving multinodular goiter, hypothyroidism, and primary amenorrhea. A 24-year-old woman with a history of multinodular goiter and hypothyroidism attended an endocrine clinic with fine-needle aspiration cytology (FNAC) report of her bilateral thyroid nodules, which showed Bethesda category IV. She had a history of learning difficulties. During detailed history-taking, the patient also complained of primary amenorrhea. Clinical examination showed a lack of secondary sexual characters. Biochemical, imaging, and cytogenetic investigations were suggestive of absent ovaries and fallopian tubes, streaked uterus, hypergonadotropic hypogonadism, and X0 karyotyping. The learning objectives of this case report are as follows: firstly, in countries with a lack of awareness and limited health resources, patients may present with one of the manifestations of Turner's syndrome. Clinicians from all specialties should be aware of the clinical features of this relatively rare entity and should try to make the most of incidental clinical findings. Secondly, clinicians should be more vigilant and thorough in their clinical assessment of patients with learning difficulties to minimize the chances of missing a clinical diagnosis.

Abstract
CONTEXT Precise genotype-phenotype correlations in Turner syndrome (TS) have not yet been deciphered. The chromosomal basis of the clinical TS phenotype in the absence of X chromosome aberrations on conventional karyotyping remains more and less unexplored. OBJECTIVE To elucidate the high-resolution chromosomal picture and analyze the genotype-phenotype associations in girls with clinical phenotype of TS by chromosomal microarray. DESIGN AND PATIENTS Cross sectional observational study conducted between October 2018 and January 2020 on 47 girls presenting the clinical TS phenotype and fulfilling the criteria for chromosomal analysis. SETTING Outpatient department at Department of Endocrinology and the Molecular Research Lab at tertiary care teaching institution. RESULTS The copy number variation (CNV) polymorphs were more frequent on autosomes than X chromosomes, and they were detected in 89.3%, 61.7%, and 92.8% of patients, respectively, on chromosome 14 or X or both. A total 445 and 64 CNV polymorphs were discovered on chromosome X and 14, respectively. The latter exhibited either gain at 14q32.33, loss at 14q11.2, or both. Karyotype was available for 27 patients; 55.6% of cases displayed X chromosome abnormalities while 44.4% cases had a normal karyotype. Functional interactomes of the genes that were present in chromosome 14 CNVs and those known to be associated with TS showed an overlap of 67% and enriched various development-related cellular pathways underlying TS phenotype. CONCLUSIONS On high-resolution karyotype analysis, clinical phenotype of TS can be associated with CNV defects in autosomes, specifically chromosome 14 or X chromosome or both. The syndrome of chromosome 14 CNV defects with and without X-chromosomal defects clinically mimics TS and shares a common genomic network that deserves further investigations.

Abstract
Turner syndrome (TS), or Bonnevie-Ullrich syndrome, also known as congenital ovarian hypoplasia syndrome, is the most common sex chromosome abnormality in females in approximately 1 in 2000 live birth. It occurs when the X chromosome is partially or completely missing in females caused by monosomy or structural abnormalities of the X chromosome. It is mainly diagnosed in late childhood or adolescent age and rarely identified during the neonatal period. It is characterized by short stature, webbed neck, lymphedema of extremities, widely spaced-out nipples, and cubital valgus. Early diagnosis of TS allows for appropriate and timely initiation of therapy with comprehensive care. We report a case of a neonate presented with the complaint of edema of feet since birth and syndromic features. TS was diagnosed by the chromosomal analysis, which demonstrated a gene karyotype of 46.X,i(X)(q10){20}.

Abstract
In healthy adolescents, delayed pubarche is generally a benign condition that is caused by a physiological discrepancy between gonadarche and adrenarche. In presence of other clinical signs and symptoms, delayed pubarche can be caused by single or multiple hormones deficiency (such as adrenal insufficiency, panhypopituitarism and hypothyroidism) and/or genetic conditions (Turner syndrome, androgen insensitivity syndrome). Exposition to endocrine disruptors has also been described as a possible cause of delay of pubic hair development. Basic blood tests, karyotype and first level imaging studies are helpful in the differential diagnosis.

Abstract
Congenital heart disease (CHD) is the most common human birth defect and remains a leading cause of mortality in childhood. Although advances in clinical management have improved the survival of children with CHD, adult survivors commonly experience cardiac and non-cardiac comorbidities, which affect quality of life and prognosis. Therefore, the elucidation of genetic etiologies of CHD not only has important clinical implications for genetic counseling of patients and families but may also impact clinical outcomes by identifying at-risk patients. Recent advancements in genetic technologies, including massively parallel sequencing, have allowed for the discovery of new genetic etiologies for CHD. Although variant prioritization and interpretation of pathogenicity remain challenges in the field of CHD genomics, advances in single-cell genomics and functional genomics using cellular and animal models of CHD have the potential to provide novel insights into the underlying mechanisms of CHD and its associated morbidities. In this review, we provide an updated summary of the established genetic contributors to CHD and discuss recent advances in our understanding of the genetic architecture of CHD along with current challenges with the interpretation of genetic variation. Furthermore, we highlight the clinical implications of genetic findings to predict and potentially improve clinical outcomes in patients with CHD.

Abstract
Premature ovarian insufficiency (POI) is defined as a loss of ovarian function before the age of 40 years, with a prevalence rate estimated at approximately 1%. It causes infertility and is related to serious long-term health consequences, including reduced life expectancy, increased cardiovascular risk, decreased bone mineral density and neurological disorders. There is currently no effective therapy for POI that is widely available in clinical practice; therefore, the treatment of patients with POI is based on hormone replacement therapy. One of the recent advances in the understanding of the pathophysiology of POI has been the role of microRNAs (miRNAs) and other noncoding RNAs (ncRNAs) in the disease. Moreover, intensive research on human folliculogenesis and reproductive biology has led to the development of novel promising therapeutic strategies with the use of exosomal miRNAs derived from mesenchymal stem cells to restore ovarian function in POI patients. This narrative review focuses on the new studies concerning the role of ncRNAs in the pathogenesis of POI, together with their potential as biomarkers of the disease and targets for therapy.

Abstract
Primary biliary cholangitis (PBC) is a rare autoimmune disease of the liver affecting the small bile ducts. From a genetic point of view, PBC is a complex trait and several genetic and environmental factors have been called in action to explain its etiopathogenesis. Similarly to other complex traits, PBC has benefited from the introduction of genome-wide association studies (GWAS), which identified many variants predisposing or protecting toward the development of the disease. While a progressive endeavour toward the characterization of candidate loci and downstream pathways is currently ongoing, there is still a relatively large portion of heritability of PBC to be revealed. In addition, genetic variation behind progression of the disease and therapeutic response are mostly to be investigated yet. This review outlines the state-of-the-art regarding the genetic architecture of PBC and provides some hints for future investigations, focusing on the study of gene-gene interactions, the application of whole-genome sequencing techniques, and the investigation of X chromosome that can be helpful to cover the missing heritability gap in PBC.

Abstract
PURPOSE Mutual cooperation of biodosimetry laboratories is required for dose assessments of large numbers of people with potential radiation exposure, as in mass casualty accidents. We launched an intercomparison exercise to validate the performance of biodosimetry laboratories in South Korea. MATERIALS AND METHODS Participating laboratories shared metaphase images from dicentric chromosome assays (DCAs) and fluorescence in situ hybridization (FISH)-based translocation assays, which were evaluated based on their own scoring protocols. RESULTS Overall, the coefficient of variation among three laboratories was less than 10% for counting scorable metaphases and chromosomal aberrations. However, there was variation in the interpretation of the International Atomic Energy Agency guidelines for selecting scorable metaphases and identifying chromosomal aberrations. In a technical workshop, scoring discrepancies were extensively discussed in order to harmonize biodosimetry protocols in Korea. In addition, metaphase images with agreement among all participating laboratories were compiled into an image databank, which can be used for education and training of scorers. CONCLUSIONS These findings and exercises may improve the accuracy of dose assessment, as well as increase the capacity for biodosimetry in South Korea.

Abstract
OBJECTIVE Turner syndrome (TS) is a congenital disease characterized by delayed puberty, ovarian dysgenesis and short stature. Although most patients are diagnosed with primary amenorrhea, approximately 15-20% of patients with TS are reported to have spontaneous menarche. However, little is known about their menstruation status after spontaneous menarche. In the current study, we investigated the menstrual abnormalities after spontaneous menarche in TS patients. DESIGN Retrospective study. PATIENTS This study included TS patients with spontaneous menarche at Osaka Police Hospital or Komura Women's Clinic between April 2015 and December 2019. MEASUREMENTS Data regarding the age of menarche, menstruation status and chromosomal karyotype were collected and retrospectively analyzed. RESULTS Of 172 TS patients, 32 with spontaneous menarche were identified. The median age of menarche was 12 years old. Premature ovarian insufficiency (POI) after menarche was observed in 12 patients (37.5%) and the median age at menopause was 20 years old. The average period from spontaneous menarche to menopause in these patients was 5.1 years. Five patients (15.6%) had irregular menstruation and 15 (46.9%) had regular menstruation. When examined according to the structural abnormality of the X chromosome, all patients with structural abnormality of the X chromosome were diagnosed with POI after spontaneous menarche, and none with mosaic without structural abnormality were diagnosed with POI. CONCLUSION Approximately one-third of TS patients with spontaneous menarche were diagnosed with POI after menarche for an average of 5.1 years. Counseling is required for TS patients and their parents, including information about menstrual abnormalities or fertility preservation.

Abstract
Importance Turner syndrome (TS) is one of the most common chromosomal abnormalities in women. The condition is characterized by gonadal dysgenesis and is associated with structural cardiac abnormalities. Assisted reproductive technology with oocyte donation may be successful but places women with TS at increased risk of aortic dissection and death. Objective To summarize all cases of aortic dissection associated with pregnancy in women with TS and provide guidance regarding the safety of pregnancy. Evidence Acquisition Systematic review of PubMed for reports of women with TS, aortic dissection, and pregnancy. Results There are 14 total reported cases of aortic dissection associated with pregnancy in women with TS. Ten of these cases occurred during pregnancy or in the first month postpartum. The majority of affected pregnancies resulted from oocyte donation, 2 of which were multiple gestations. Two women had a documented history of hypertension, and 3 pregnancies were complicated by preeclampsia. Bicuspid aortic valve and coarctation of the aorta were the most common associated cardiac anomalies. More than half of women had some degree of aortic dilatation. Two women had no identifiable risk factors. Conclusions and Relevance Women with TS who desire pregnancy must be thoroughly counseled regarding the increased risk of aortic dissection during pregnancy and postpartum. Preconception consultation with maternal-fetal medicine, reproductive endocrinology, and cardiology is necessary along with a comprehensive physical evaluation. If women with TS choose to pursue pregnancy, they require rigorous cardiac monitoring each trimester during pregnancy and postpartum.

Abstract
CONTEXT Adult height is highly heritable, yet no genetic predictor has demonstrated clinical utility compared to mid-parental height. OBJECTIVE To develop a polygenic risk score for adult height and evaluate its clinical utility. DESIGN A polygenic risk score was constructed based on meta-analysis of genomewide association studies and evaluated on the Avon Longitudinal Study of Parents and Children (ALSPAC) cohort. SUBJECTS Participants included 442 599 genotyped White British individuals in the UK Biobank and 941 genotyped child-parent trios of European ancestry in the ALSPAC cohort. INTERVENTIONS None. MAIN OUTCOME MEASURES Standing height was measured using stadiometer; Standing height 2 SDs below the sex-specific population average was considered as short stature. RESULTS Combined with sex, a polygenic risk score captured 71.1% of the total variance in adult height in the UK Biobank. In the ALSPAC cohort, the polygenic risk score was able to identify children who developed adulthood short stature with an area under the receiver operating characteristic curve (AUROC) of 0.84, which is close to that of mid-parental height. Combining this polygenic risk score with mid-parental height or only one of the child's parent's height could improve the AUROC to at most 0.90. The polygenic risk score could also substitute mid-parental height in age-specific Khamis-Roche height predictors and achieve an equally strong discriminative power in identifying children with a short stature in adulthood. CONCLUSIONS A polygenic risk score could be considered as an alternative or adjunct to mid-parental height to improve screening for children at risk of developing short stature in adulthood in European ancestry populations.

Abstract
BACKGROUND Miscarriage describes the spontaneous loss of pregnancy before the threshold of viability; the vast majority occur before 12 weeks of gestation. Miscarriage affects one in four couples and is the most common complication of pregnancy. Chromosomal abnormalities of the embryo are identified in ∼50% of first trimester miscarriages; aneuploidy accounts for 86% of these cases. The majority of trisomic miscarriages are of maternal origin with errors occurring during meiotic division of the oocytes. Chromosome segregation errors in oocytes may be sporadic events secondary to advancing maternal age; however, there is increasing evidence to suggest possible maternal germline contributions to this. OBJECTIVE AND RATIONALE The objective of this review was to appraise critically the existing evidence relating to maternal germline factors associated with pregnancy loss secondary to embryo aneuploidy, identify limitations in the current evidence base and establish areas requiring further research. SEARCH METHODS The initial literature search was performed in September 2019 and updated in January 2021 using the electronic databases OVID MEDLINE, EMBASE and the Cochrane Library. No time or language restrictions were applied to the searches and only primary research was included. Participants were women who had suffered pregnancy loss secondary to numerical chromosomal abnormalities of the embryo. Study identification and subsequent data extraction were performed by two authors independently. The Newcastle-Ottawa Scale was used to judge the quality of the included studies. The results were synthesized narratively. OUTCOMES The literature search identified 2198 titles once duplicates were removed, of which 21 were eligible for inclusion in this systematic review. They reported on maternal germline factors having variable degrees of association with pregnancy loss of aneuploid origin. The Online Mendelian Inheritance in Man (OMIM) gene ontology database was used as a reference to establish the functional role currently attributed to the genes reported. The majority of the cases reported and included were secondary to the inheritance of maternal structural factors such as Robertsonian translocations, deletions and insertions. Germline factors with a plausible role in aneuploid pregnancy loss of maternal origin included skewed X-inactivation and CGG repeats in the fragile X mental retardation (FMR1) gene. Studies that reported the association of single gene mutations with aneuploid pregnancy loss were conflicting. Single gene mutations with an uncertain or no role in aneuploid pregnancy loss included mutations in synaptonemal complex protein 3 (SYCP3), mitotic polo-like kinase 4 (PLK4) and meiotic stromal antigen 3 (STAG3) spindle integrity variants and 5,10-methylenetetrahydrofolate reductase (MTHFR). WIDER IMPLICATIONS Identifying maternal genetic factors associated with an increased risk of aneuploidy will expand our understanding of cell division, non-disjunction and miscarriage secondary to embryo aneuploidy. The candidate germline factors identified may be incorporated in a screening panel for women suffering miscarriage of aneuploidy aetiology to facilitate counselling for subsequent pregnancies.

Abstract
Turner syndrome (TS) is a relatively common chromosomal abnormality in females. Short stature, gonadal dysgenesis, and somatic dysmorphic features are the characteristic features of the syndrome. The chromosomal abnormalities of TS are highly variable; 45,X/46,XY mosaicism accounts for 10-12% of cases of Turner syndrome. Despite the presence of hypogonadism, affected females typically have a uterus. Here, we report the case of a 22-year-old female who presented at 15 years of age with primary amenorrhea. She was diagnosed with Turner syndrome mosaicism with a karyotype of 45,X/46,XY. Her pelvic imaging showed an absent uterus and ovaries. Due to the presence of a Y chromosome, she underwent prophylactic gonadectomy. Histopathology of her removed gonads confirmed the diagnosis of mixed gonadal disorder. She was started on estrogen replacement. Four years after treatment, she developed her menses. Her repeated pelvic magnetic resonance imaging showed the presence of a small uterus.

Added value of buccal cell FISH analysis in the diagnosis and management of Turner syndrome. Hum Reprod 2021; 35:2391-2398.

Abstract
STUDY QUESTION Is there an added diagnosis value of buccal cell FISH analysis compared with blood lymphocyte chromosomal investigations in patients with Turner syndrome (TS)? SUMMARY ANSWER Buccal cell FISH analysis, a non-invasive technique, modified the chromosomal results obtained with the blood karyotype in 17 patients (12%) of our cohort. WHAT IS KNOWN ALREADY Few studies have evaluated buccal cell FISH analysis and compared them with blood karyotype in patients with TS. STUDY DESIGN, SIZE, DURATION A prospective, monocentric cohort study was conducted in a rare diseases centre (CMERC) between July 2017 and August 2019. PARTICIPANTS/MATERIALS, SETTING, METHODS In total, 142 adult patients with TS, and at least 5% 45,X cells in a previous blood karyotype, were recruited. All the patients' files were included in the CEMARA database. This national database has been declared to the French data protection agency (CNIL approval number 1187326). In compliance with French law, consent regarding non-opposition to collect and use the data was obtained from each patient. A FISH analysis on a buccal smear was performed. MAIN RESULTS AND THE ROLE OF CHANCE The percentage of 45,X cells was identical between the two tissues in only 32.4% of cases. The discrepancy was higher than 41% for 12% of the cohort. The percentage of 45,X cells was higher in blood in 53 (37.3%) patients, and higher in buccal cells in 43 (30.3%) of cases. In 17 (12%) cases, the blood karyotype had to be reconsidered in regard to the buccal cell analysis. LIMITATIONS, REASONS FOR CAUTION It would have been interesting to evaluate karyotypes in cells from other tissues such as cells from skin biopsy or from the urinary tract and even from blood vessels or gonads in case of surgery and to compare them with each patient's phenotype. However, most of the time, these tissues are not available. WIDER IMPLICATIONS OF THE FINDINGS Although blood lymphocyte karyotype remains the gold standard for the diagnosis of TS, buccal cell FISH analysis is an efficient tool to evaluate the global chromosomal constitution in these patients, thus allowing them to have better care and follow-up. For instance, identifying a Y chromosome can prevent the occurrence of a gonadoblastoma, as gonadectomy should be discussed. On the other hand, finding normal XX cells in a patient with a previous diagnosis of homogenous 45,X TS, may be psychologically helpful and relevant for gynaecological care. STUDY FUNDING/COMPETING INTEREST(S) No specific funding was sought for the study. The authors declare no competing interests. TRIAL REGISTRATION NUMBER N/A.

Abstract
BACKGROUND A Turner Syndrome (TS) Transition clinic, Royal Hospital for Children Glasgow (RHCG), with paediatric and adult endocrinology/gynaecology teams was established in 1998 with an aim of improving health outcomes in TS throughout the lifespan. OBJECTIVE To evaluate the success of our TS transition service, focussing on evaluating established follow-up after transfer to adult services. METHODS Girls attending the TS Transition clinic at Royal Hospital for Children Glasgow, 1998-2017, were identified. Attendance data were obtained from patient records and an electronic appointment system. We assessed good and late early attendance in our cohort of TS patients as well as established endocrine follow-up, defined as those still attending adult endocrine services 3 years after transfer. Success of TS transition was determined by the proportion of girls in established endocrine follow-up. RESULTS Forty-six girls (median age 18.3 yrs) were identified. Thirty-six, 36/46 girls transferred prior to 2015 and 26 of those (72%) were in established follow-up at 3 years, 22/36 girls had met with an Adult specialist prior to transfer and 14/36 had not met with an adult specialist prior to transfer. Twenty-one (80.7%) were good early attenders (p = 0.10). In the early attenders' cohort, there was no significant difference between those that had and had not met an adult specialist prior to transfer. CONCLUSION A significant proportion of girls with TS are currently lost to endocrine follow-up following transfer to adult clinics. Early attendance at an adult clinic appears to predict established long-term follow-up. Strategies to improve early attendance and long-term endocrine follow-up are needed to ensure lifelong health needs are addressed.

Abstract
INTRODUCTION Sex chromosome aneuploidies (SCAs) are among the most common chromosome abnormalities observed in humans. Manifestations include low fertility, infertility, delayed language development, and dysfunction in motor development. Noninvasive prenatal screening (NIPS) based on cell-free fetal DNA from the peripheral blood of pregnant women is increasingly used for the screening of fetal chromosome abnormalities, including screening for fetal gender and fetal sex chromosome aneuploidy. A systematic review of the literature about NIPS for SCAs is needed. AREAS COVERED This review evaluated a vast array of published studies focusing on the clinical significance, detection methods, performance of NIPS for SCAs, and the management of positive SCA results following screening with the aim of facilitating a comprehensive and systematic understanding of NIPS for SCAs. EXPERT COMMENTARY Looking forward, NIPS is expected to become the primary screening test for common aneuploidies as well as other chromosome abnormalities, including some micro-deletions and micro-duplications, with the potential to transition from a screening test to a prenatal diagnosis method. Ultimately, the goal is to provide a safe and accurate method for increasing early diagnosis to improve long-term outcomes for the SCA patients and families by well- informed health care providers.

Abstract
Accelerated bone loss and muscle loss coexist in women with premature ovarian insufficiency (POI), but there are significant gaps in our understanding of musculoskeletal health in POI. This review describes estrogen signaling in bone and its role in skeletal health and disease. Possible mechanisms contributing to bone loss in different forms of POI and current evidence regarding the utility of available diagnostic tests and therapeutic options are also discussed. A literature review from January 2000 to March 2020 was conducted to identify relevant studies. Women with POI experience significant deterioration in musculoskeletal health due to the loss of protective effects of estrogen. In bone, loss of bone mineral density (BMD) and compromised bone quality result in increased fracture risk; however, tools to assess bone quality such as trabecular bone score (TBS) need to be validated in this population. Timely initiation of HRT is recommended to minimize the deleterious effects of estrogen deficiency on bone in the absence of contraindications; however, the ideal estrogen replacement regimen remains unknown. POI is associated with compromised bone health, regardless of the etiology. Ongoing research is warranted to refine our management strategies to preserve bone health in women with POI.

Abstract
PURPOSE The purpose of this study is to explore the reproductive outcomes of women with Turner syndrome (TS) in preimplantation genetic testing (PGT) cycles. METHODS A retrospective study of 100 controlled ovarian stimulating cycles, 68 TS (sixty-four mosaic Turner syndrome (MTS) and four pure Turner syndrome (PTS)) women underwent PGT was conducted from 2013 to 2018. RESULTS Embryo X chromosome abnormal rates of TS women were significantly higher than women with normal karyotype (7.04 vs 1.61%, P<0.01). Cumulative live birth rates (CLBR) after PGT-NGS treatment were lower in TS than control (31.15 vs 45.59%, P<0.05). Clinical pregnancy rates per transfer (CPR), miscarriage rates (MR) and live birth rates per transfer (LBR) remained comparable between TS and control group. Reproductive outcomes (X chromosome abnormal rates, CPR, MR, LBR and CLBR) among low (<10%), medium (10-50%) and high (>50%) level 45,X mosaicism groups were not statistically different. CONCLUSIONS To avoid high risk of embryo X chromosome abnormalities, prenatal or preimplantation genetic testing should be recommended to mosaic or pure TS patients.

Abstract
Fetal echocardiography is now commonly used to assess fetuses for congenital heart disease. To care for their patients, it is important for the pediatrician to understand the utility of the test, the benefits, and the limitations of the results. This review outlines the indications, components, and limitations of fetal echocardiography with a focus on the care that the pediatrician provides to newborns and their families. An understanding of the fetal cardiac examination can assist the pediatrician in caring for patients with either normal or abnormal test results. The need for and timing of postnatal cardiology follow-up, and guidance on referral for fetal echocardiogram for future pregnancies are all critical roles that the pediatrician can play. Most importantly, an understanding of the limitations, including difficult-to-diagnose lesions, allows the pediatrician to maintain a high level of suspicion for cardiac defects regardless of fetal echocardiography findings.

Abstract
BACKGROUND Turner syndrome (TS) is a chromosomal disorder with various complications, including congenital anomaly of the kidney and urinary tract (CAKUT). However, its renal function remains poorly known. Therefore, this study aimed to evaluate renal function in TS of various ages from childhood to adulthood. METHODS We retrospectively analyzed 63 patients with TS who visited our hospital between 1989 and 2020, examined their renal morphology, and analyzed renal function by calculating the estimated glomerular filtration rate (eGFR) using formulas applicable for Japanese populations. RESULTS Renal morphological abnormality was observed in 22 cases (35.0%) (horseshoe kidney, 7 [11.1%]; hydronephrosis, 11 [17.5%]; duplex collecting system, 3 [4.8%]; and single unilateral kidney, 1 [1.6%]). We evaluated the eGFR of 47 subjects aged 2.8-39.3 years and classified them into Group 1 (with CAKUT, n = 15) and Group 2 (without CAKUT, n = 32). The eGFR at the first visit and the final follow-up was not statistically different between these groups. In Group 1 with CAKUT, the eGFR was not significantly different between that at the first visit and that at the final follow-up (p = 0.21). During the observation period (median, 7.9 years), the eGFR of all individuals in both groups gradually decreased with age, but did not fall < 60 mL/min/1.73 m2, which defines chronic kidney disease (CKD). CONCLUSIONS The renal function of TS remained normal in all cases during our investigation period, and no one developed CKD by the age of 40 years.

Turner's syndrome mosaicism in girls with neurodevelopmental disorders: a cohort study and hypothesis. Mol Cytogenet 2021; 14:9. [PMID: 33573679 PMCID: PMC7879607 DOI: 10.1186/s13039-021-00529-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2020] [Accepted: 01/14/2021] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Turner's syndrome is associated with either monosomy or a wide spectrum of structural rearrangements of chromosome X. Despite the interest in studying (somatic) chromosomal mosaicism, Turner's syndrome mosaicism (TSM) remains to be fully described. This is especially true for the analysis of TSM in clinical cohorts (e.g. cohorts of individuals with neurodevelopmental disorders). Here, we present the results of studying TSM in a large cohort of girls with neurodevelopmental disorders and a hypothesis highlighting the diagnostic and prognostic value. RESULTS Turner's syndrome-associated karyotypes were revealed in 111 (2.8%) of 4021 girls. Regular Turner's syndrome-associated karyotypes were detected in 35 girls (0.9%). TSM was uncovered in 76 girls (1.9%). TSM manifested as mosaic aneuploidy (45,X/46,XX; 45,X/47,XXX/46,XX; 45,X/47,XXX) affected 47 girls (1.2%). Supernumerary marker chromosomes derived from chromosome X have been identified in 11 girls with TSM (0.3%). Isochromosomes iX(q) was found in 12 cases (0.3%); one case was non-mosaic. TSM associated with ring chromosomes was revealed in 5 girls (0.1%). CONCLUSION The present cohort study provides data on the involvement of TSM in neurodevelopmental disorders among females. Thus, TSM may be an element of pathogenic cascades in brain diseases (i.e. neurodegenerative and psychiatric disorders). Our data allowed us to propose a hypothesis concerning ontogenetic variability of TSM levels. Accordingly, it appears that molecular cytogenetic monitoring of TSM, which is a likely risk factor/biomarker for adult-onset multifactorial diseases, is required.

Abstract
AIMS Turner syndrome is the only chromosome monosomy that is postnatally compatible with life. The reported incidence of TS is 1 in 2500 liveborn girls. The phenotype of these girls is highly variable, with cardiac abnormalities being life-threatening defects. The aim of the study was to reveal the possible influence of the parental origin of the X chromosome in these patients on a selected phenotype that is associated with Turner syndrome. Selected symptoms and parameters were: a bicuspid aortic valve, aortic coarctation, lymphoedema, pterygium colli, coeliac disease, thyroiditis, otitis media, diabetes mellitus 2, renal abnormalities, spontaneous puberty, and IVF. METHODS The X chromosome haplotype was determined for a group of 45,X patients verified by native FISH. A molecular diagnostic method based on the detection of different lengths of X chromosome-linked STR markers using the Argus X-12 QS kit was used to determine the X haplotype. RESULTS Our results, analysed by Fisher's exact (factorial) test, suggest independence between the maternal/paternal origin of the inherited X chromosome and the presence of the anomalies that were studied (P=1 to P=0.34). CONCLUSION In the group of 45,X patients, who were precisely selected by means of the native FISH method, no correlation was demonstrated with the parental origin of the X chromosome and the observed symptom.

Front Endocrinol (Lausanne) 2021; 12:722199.

Abstract
BACKGROUND Turner syndrome (TS) presents a high risk of congenital heart defects and may predispose to both obesity and related metabolic complications. Hence the search for new markers as potential early predictors of the metabolic syndrome (MetS) and cardiovascular diseases appears warranted. OBJECTIVE To assess MMP-1 (matrix metalloproteinase-1), MMP-2 (matrix metalloproteinase-2), MMP-9 (matrix metallopeptidase-9), BDNF (brain-derived neurotrophic factor), GDNF (glial cell line-derived neurotrophic factor), and VEGF (vascular endothelial growth factor) in non-MetS TS girls not treated with growth hormone (GH) vs. healthy short stature girls, and to assess the connection with basic metabolic parameters. METHOD The concentrations of circulating MMP-1, MMP-2, MMP-9, BDNF, GDNF and VEGF were measured in 12 patients with TS not treated with growth hormone. The control group was composed of 17 girls with non-pathologic short stature. The patients' clinical and biochemical phenotypes were determined by weight, height, total cholesterol, HDL cholesterol, triglycerides, glucose, aminotransferases, IGF1, TSH and fT4. RESULTS There were no differences in mean age, weight, BMI Z-Score, or hSDS between the studied group and the controls; however, they differed in baseline values of ALT (18.2 ± 4.2 vs. 14.2 ± 4.1, p= 0.02), BDNF [29951.5 (26176.9 - 41271.9) vs. 23131.7 (18392.4 - 28313.3), p=0.01] and MMP-2 [91.8 (71.7 - 111.0) vs. 143.6 (123.7 - 244.5), p< 0.001]. BDNF correlated with ALT activity (r = 0.56 p = 0.002) and BMI Z-score (r = 0.38 p = 0.042), while MMP-2 correlated with HDL concentration (r = 0.48 p = 0.029) in all the patients. The analysis of the study group alone revealed significant positive correlations between MMP-9 and TSH (r = 0.74 p = 0.036), BDNF and both ALT (r = 0.73 p = 0.038) and TSH (r = 0.85 p = 0.008), and a negative correlation between MMP-1 and fT4 (r = -0.75 p = 0.032). The control group did not present any significant correlations. CONCLUSION The higher concentrations of BDNF and lower of MMP-2 found in girls with TS without MetS compared to healthy girls with short stature, could have a major impact on the future "natural" development of the metabolic status. Our findings need further studies.
