Abstract
RATIONALE Coexistence of congenital adrenal hyperplasia due to 21-hydroxylase deficiency, Graves' disease and 47, XXX is rare. We report a case of a 25-year-old woman presented with masculine appearance, hirsutism and enlarged clitoris. Lab tests showed elevated serum 17 hydroxyprogesterone, testosterone, dehydroepiandrosterone. Gene test revealed heterozygous gene mutation in CYP21A2:NM_000500:exon4:c.518 T > A, NM_000500:exon8:c.C1024T. Karyotype analysis showed 47, XXX. After prednisone replacement and antithyroid therapy, she got a normal menstruation and normal level of testosterone. These findings demonstrate that patients with abnormal chromosome are likely to combine 21-hydroxylase deficiency (21-OHD), thus karyotyping test should not be neglected for those who have been already diagnosed as 21-OHD. Additionally, chromosomal abnormality such as 47, XXX and Turner syndrome had susceptibility to develop autoimmune thyroid disease because a gene on X chromosome may be responsible for the occurrence of autoimmune thyroid disease. Moreover, both 21-OHD and Graves' disease (GD) can lead to high level of testosterone, thus we should keep in mind to test chromosome and thyroid function in 21-OHD patients to avoid misdiagnose or missed diagnosis. To the best of our knowledge, this is the first report of simple virilizing (SV) 21-OHD patient combined with 47, XXX and Graves disease. PATIENT CONCERNS A 24-years-old female of Han ethnicity was admitted to the endocrinology department complaining of absence of menses for half a year. The patient didn't noticed her enlarged clitoris until she was 17 years old. Her menarche was 16 years old and the final height was 163 centimeter. She was diagnosed with GD 2 months before admission to our hospital due to palpitation, heat intolerance, muscle weakness. DIAGNOSES The patient was diagnosed with SV 21-OHD, Graves disease and 47, XXX. INTERVENTIONS At first, the patient was given 10 mg methimazole twice a day as well as 5 mg predisone in the morning and 2.5 mg in the evening. After a year of regular medication and reexamination, she got a regular menstruation and thyroid function and now is taking 2.5 mg prednisone twice a day. OUTCOMES The patient got a regular menstruation and thyroid function. Laboratory results showed: testosterone declined to 0.1nmol/L (0.1-1.67nmol/L) and 17 hydroxyprogesterone get back to normal level: 1.01ng/ml (0.30-2.34ng/mL). However, her enlarged clitoris has not narrowed. LESSONS Patients with abnormal chromosome are likely to combine 21-OHD, thus karyotyping test should not be neglected for those who have been already diagnosed as 21-OHD. Additionally, chromosomal abnormality such as 47, XXX and Turner syndrome had susceptibility to develop autoimmune thyroid disease because a gene on X chromosome may be responsible for the occurrence of autoimmune thyroid disease. Moreover, both 21-OHD and GD can lead to high level of testosterone, thus we should keep in mind to test chromosome and thyroid function in 21-OHD patients to avoid misdiagnose or missed diagnosis. To the best of our knowledge, this is the first report of SV 21-OHD patient combined with 47, XXX and Graves disease.

World J Clin Cases 2021; 9:2259-2267. [PMID: 33869601 PMCID: PMC8026834 DOI: 10.12998/wjcc.v9.i10.2259] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2020] [Revised: 01/10/2021] [Accepted: 01/27/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Co-morbidity of SRY gene turner syndrome (TS) with positive SRY gene and non-classical congenital adrenal hyperplasia (NCAH) is extremely rare and has never been reported to date.
CASE SUMMARY In this article, we present a 14-year-old girl who was referred to our hospital with short stature (weight of 43 kg and height of 143 cm, < -2 SD) with no secondary sexual characteristics (labia minora dysplasia). Laboratory tests indicated hypergonadotropic hypogonadism with significantly increased androstenedione and 17-hydroxyprogesterone (17-OHP) levels. This was accompanied by the thickening of the extremity of the left adrenal medial limb. The patient’s karyotype was 45,X/46,X, +mar, and cytogenetic analysis using multiplex ligation-dependent probe amplification and high-throughput sequencing indicated that the SRY gene was positive with compound heterozygous mutations in CYP21A2 as the causative gene for congenital adrenal hyperplasia. The sites of the suspected candidate mutations were amplified and verified using Sanger sequencing. The patient was finally diagnosed as having SRY positive TS with NCAH. The patient and her family initially refused medical treatment. At her most recent follow-up visit (age = 15 years old), the patient presented facial hair, height increase to 148 cm, and weight of 52 kg, while androstenedione and 17-OHP levels remained high. The patient was finally willing to take small doses of hydrocortisone (10 mg/d).
CONCLUSION In conclusion, upon evaluation of the patient mentioned in the report, we feel that 17-OHP measurement and cytogenetic analysis are necessary for TS patients even in the absence of significant virilization signs. This will play a significant role in guiding diagnosis and treatment.

Horm Behav 2020; 126:104867. [PMID: 32998030 DOI: 10.1016/j.yhbeh.2020.104867] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2020] [Revised: 09/18/2020] [Accepted: 09/19/2020] [Indexed: 01/15/2023]
Abstract
The ratio of length between the second and fourth fingers (2D:4D) is commonly used as an indicator of prenatal sex hormone exposure. Several approaches have been used to try to validate the measure, including examining 2D:4D in people with congenital adrenal hyperplasia (CAH), a suite of conditions characterised by elevated adrenal androgen production secondary to defective steroidogenesis. We present a systematic review and meta-analysis that examines the relationship between these two variables. Twelve articles relating to nine CAH cohorts were identified, and 2D:4D comparisons have been made between cases and controls in eight of these cohorts. Altogether, at least one 2D:4D variable has been compared between n = 251 females with CAH and n = 358 unaffected females, and between n = 108 males with CAH and n = 204 unaffected males. A previous meta-analysis (Hönekopp and Watson, 2010) reported lower right hand (R2D:4D) and left hand (L2D:4D) digit ratios in patients with CAH relative to sex-matched controls. Our meta-analysis showed the same pattern, with medium effect sizes for R2D:4D and small effect sizes for L2D:4D. Differences of small magnitude were also observed for M2D:4D, and no significant effects were observed for D[R-L]. Notably, the only effects that remained statistically significant when stratified by sex were R2D:4D in males and L2D:4D in females, and the average effect size had reduced by 46.70% since the meta-analysis of Hönekopp and Watson (2010). We also found that individual comparisons in this literature were considerably underpowered, and that patterns of sexual dimorphism in 2D:4D were similar in CAH samples as in typically developing populations. Findings are discussed in relation to the prenatal androgen hypothesis as well as alternative explanations.

Abstract
Background 21‐hydroxylase deficiency (21‐OHD) is caused due to CYP21A2 gene variant. In males, the excess androgens produce varying degrees of penile enlargement and small testes. CHARGE syndrome (CS) has a broad spectrum of symptoms. In males, genital features such as micropenis and cryptorchidism are found in 48% of CS. There are no reports of patients with combined 21‐OHD and CS; therefore, it is unknown whether the external genitalia shows penile enlargement or micropenis with/without cryptorchidism. Case A boy, born at 37 weeks and 5 days of gestational age with no consanguineous marriage, was admitted to our hospital due to congenital cleft lip, cleft palate, micropenis, cryptorchidism, and a ventricular septal defect. He had severe hyponatremia and hyperkalemia on day 10. He was diagnosed to have 21‐OHD and CS. His external genitalia demonstrated both cryptorchidism and micropenis, but not penile enlargement. Methods DNA was extracted from peripheral leukocytes using standard procedures. Sanger sequence was performed in CYP21A2. Exome sequence was performed, and then, Sanger sequence was performed around variant in CHD7. Results Genetic screening for CYP21A2 gene was performed and compound heterozygous variants of c.293‐13A/C>G (IVS2‐13A/C>G) and c.518T>A (p.I172N) were detected in chromosome 6p21.3. His mother had been heterozygous variant of c.293‐13A/C>G, and his father had been heterozygous variant of c.518T>A. Simultaneously, a de novo splicing acceptor alteration in c.7165–4 A>G, in chromodomain helicase DNA binding protein‐7 (CHD7), located in chromosome 8q12 was detected, and the patient was diagnosed with 21‐OHD and CS. Conclusion Although these two disorders exhibit different modes of inheritance and their co‐morbidity is extremely rare, we encountered one male patient who suffered from both 21‐OHD and CS.

Abstract
A combination of Turner syndrome (TS) and classical congenital adrenal hyperplasia (CAH) is rare. A one-day-old newborn was referred to our hospital with ambiguous genitalia. The parents were third-degree relatives. The infant's weight was 3350g (50-75p), and the head circumference was 34.5cm (50p). The gonads were nonpalpable. Presence of a 3 cm phallus, one urogenital opening into the perineum, and incomplete labial fusion were identified. Laboratory tests revealed a classical type of CAH due to 21-hydroxylase deficiency. Karyotyping revealed a 45X0(35)/46XX(22) pattern with negative sex-determining region Y (SRY) on gene analysis. At the most recent follow-up visit, the patient appeared to be in good health - her height was 70.4 cm [-1.5 standard deviation (SD)] and her weight was 9.8 kg (0.3 SD). She was receiving hydrocortisone in a dose of 10 mg/m²/day, fludrocortisone acetate in a dose of 0.075 mg/day, and oral salt of 1 g/day. System examinations were normal. The patient's electrolyte levels were found to be normal and she was in good metabolic control. The findings of this patient demonstrate that routine karyotyping during investigation of patients with sexual differentiation disorders can reveal TS. Additionally, signs of virilism should always be investigated at diagnosis or during physical examinations for follow-up of TS cases. SRY analysis should be performed primarily when signs of virilism are observed. CAH should also be considered in patients with negative SRY.

Abstract
Turner Syndrome (TS) is a common genetic disorder, affecting female individuals, resulting from the partial or complete absence of one sex chromosome, and occurring in approximately 50 per 100,000 liveborn girls. TS is associated with reduced adult height and with gonadal dysgenesis, leading to insufficient circulating levels of female sex steroids and to infertility. Morbidity and mortality are increased in TS but average intellectual performance is within the normal range. TS is closely associated to the presence of autoantibodies and autoimmune diseases (AID), especially autoimmune thyroiditis and inflammatory bowel disease. Despite the fact that the strong association between TS and AID is well known and has been widely studied, the underlying immunopathogenic mechanism remains partially unexplained. Recent studies have displayed how TS patients do not show an excess of immunogenic risk markers. This is evocative for a higher responsibility of X-chromosome abnormalities in the development of AID, and particularly of X-genes involved in immune response. For instance, the long arm of the X chromosome hosts a MHC-locus, so the loss of that region may lead to a deficiency in immune regulation. Currently no firm guidelines for diagnosis exist. In conclusion, TS is a condition associated with a number of autoimmune manifestations. Individuals with TS need life-long medical attention. As a consequence of these findings, early diagnosis and regular screening for potential associated autoimmune conditions are essential in the medical follow-up of TS patients.

Abstract
Women with Turner syndrome (TS) are at risk of premature ovarian failure. The objective of this retrospective study was to identify patients with TS who could be potential candidates for fertility preservation and to determine their present reproductive and fertility status. Criteria for fertility preservation included: (i) spontaneous menarche; (ii) confirmation by ultrasound examination of the presence of at least one normal ovary; and (iii) serum FSH concentrations below 40 IU/l. Using the Montreal Children's Hospital Cytogenetic Database from 1990 to 2006, 28 patients with complete or partial absence of one X chromosome were identified: 13 (46%) were 45,X; nine (32%) had mosaic karyotypes; and six (21%) had karyotypes containing isochromosome or ring X chromosome. Six patients (21%) had spontaneous pubertal development and four (14%) were identified as potential candidates for fertility preservation. One underwent an ovarian stimulation protocol of gonadotrophin-releasing hormone agonist down-regulation followed by recombinant FSH and human menopausal gonadotrophin stimulation. Two metaphase-II-stage oocytes were aspirated and vitrified using the McGill Cryoleaf vitrification system. Another patient conceived spontaneously at the age of 24 years. In conclusion, fertility preservation may not be feasible for most patients with TS. However, after careful consideration of increased pregnancy-associated risks, fertility preservation may be offered to young females with mosaic TS.

Abstract
BACKGROUND Most girls with Turner syndrome (TS) receive growth hormone (GH) treatment during childhood and adolescence, but controlled data on the effects on body composition and glucose metabolism are lacking. OBJECTIVE To study the effects of GH treatment on insulin sensitivity, glucose metabolism, bone turnover, and body composition. METHODS A randomized, placebo-controlled, crossover study was conducted with girls with TS. All girls with TS were treated with GH 0.1 IU/kg/d subcutaneously at bedtime or with placebo for 2 months and studied at the end of each period. Control subjects were studied once without treatment. Twelve girls with TS, aged 9.5 to 14.8 years (median: 12.9 years) and 16 age-matched control subjects (10.3-16.0 years; median: 12.1 years) were studied. Twenty-four-hour sampling of blood was performed; GH, insulin-like growth factor I (IGF-I), IGF binding proteins (IGFBPs), insulin, glucose, and lipolytic and gluconeogenic precursors were assayed, followed by an oral glucose tolerance test. Body composition was evaluated by dual-energy x-ray absorptiometry scanning and body mass index (BMI). Fasting bone markers were measured. RESULTS Height was reduced in TS as compared with control subjects. In the placebo situation, 24-hour integrated GH as well as IGF-I was significantly reduced in girls with TS compared with control subjects. Controlling for differences in lean body mass (LBM; or fat mass [FM]) and sexual development did not explain the difference in 24-hour integrated GH. Differences in sexual development, BMI, FM, insulin sensitivity, and IGFBP-3 could explain the difference in IGF-I between TS and control subjects. Carbohydrate metabolism in TS was comparable with control subjects. GH treatment induced insulin resistance, with increments in fasting glucose and insulin, as well as 24-hour insulin. Circulating levels of lipid and gluconeogenic substrates were comparable in TS and control subjects and unchanged in response to treatment. Bone markers increased in response to GH. Total FM was increased in girls with TS, accounted for by an increased FM in the arms and trunk, whereas LBM was decreased. Especially LBM in the legs was decreased. Overall, bone mineral content was diminished. Treatment with GH reduced FM in TS, especially in the arms and legs, and likewise increased total LBM, primarily in the trunk. CONCLUSION This study documented evidence of impaired GH secretion and action, disproportionate body composition, but a normal carbohydrate metabolism in girls with TS. Short-term GH administration was associated with favorable changes in body composition but also with relative impairment of glucose tolerance and insulin sensitivity. We recommend that glucose metabolism be monitored carefully during long-term GH treatment in these patients.

Abstract
We investigated a possible influence on birth weight in Turner's syndrome of many clinical, hormonal, genetic and immunogenetic variables. We considered 97 patients with Turner's syndrome. Patients with parents with identical GM (Gamma heavy chains Marker) phenotype had a significantly lower birth weight than those with parents with different GM phenotype. Karyotype other than 45,X, HLA (Human Leukocyte Antigen) parental sharing, mother-patient compatibility and elevated 17-hydroxyprogesterone (17OHP) serum level after adrenocorticotropin hormone (ACTH) and absence of heart and kidney malformations and lymphedema were associated with a lower birth weight, but not significantly. Multiple interactions showed that the presence of an identical GM phenotype in parents, together with other conditions (karyotype other than 45,X, adrenal dysfunction, HLA parental sharing, mother-child compatibility, KM(3) [Kappa light chains Marker] phenotype) resulted in a further decrease of birth weight. These data might suggest a negative effect of genetic similarity on intrauterine growth in Turner's syndrome.

Abstract
We investigated whether molecular defects in the CYP21 gene were detectable in two common sex chromosome aberrations, the Turner and the Klinefelter syndromes. We found abnormal 17-hydroxyprogesterone levels after adrenal stimulation in 26/60 (43.3%) patients affected by these chromosome aberrations, as compared with only 11/68 (16.2%) normal controls (P=0.0014, odds ratio 4.0). Screening of the CYP21 gene identified a single Val281Leu missense mutation in exon 7 in 9/63 (14.3%) of the patients, all nine of whom were heterozygote carriers; the mutation frequency was significantly higher than in the general population (P=0.007, odds ratio=3.5). The hormonal and molecular data indicate that these common sex chromosome aberrations are associated with a remarkably high frequency of steroidogenic defects. It may be hypothesised that reduced levels of steroid 21-hydroxylase could confer a survival advantage, leading to a successful pregnancy.

Abstract
OBJECTIVE To report a case of cryptic 21-hydroxylase deficiency identified at the time of ovum donation in a patient with Turner's syndrome. DESIGN Case report. SETTING University IVF practice. PATIENT(S) A 28-year-old woman with Turner's syndrome who presented for ovum donation. INTERVENTION(S) Four cycles of donor IVF. MAIN OUTCOME MEASURE(S) Pregnancy, endometrial appearance, progesterone, and 17-hydroxyprogesterone values. RESULT(S) The patient failed two fresh and two frozen ET cycles with donated oocytes. The appearance of the endometrium suggested elevated progesterone before progesterone supplementation. An elevated progesterone was detected but not suppressed by leuprolide acetate. Progesterone was suppressed by adding dexamethasone. The diagnosis of cryptic 21-hydroxylase deficiency was confirmed biochemically. CONCLUSION(S) Patients with Turner's syndrome reportedly have poorer outcomes with donor IVF than other women. They also have an increased incidence of carrying a defective 21-hydroxylase gene. We suggest that some of the poorer outcomes may be explained by the presence of elevated progesterone and recommend evaluation of possible congenital adrenal hyperplasia in patients with Turner's syndrome who want oocyte donation.

Abstract
We report on a rare case of female pseudohermaphroditism due to classical 21-hydroxylase deficiency associated with Turner syndrome (45,X/46,XX). Difficulties in the management of both diseases are briefly discussed. We regard this rare combination as a coincidental occurrence.

Abstract
HLA-B14 positive haplotypes have increased frequencies in a group of patients with puberty disorders, IgA deficiency and cancer of the ovary. Clinical investigations demonstrated that all these patients have high values of 170H progesteron after the ACTH test which suggests an alterated function of 21 hydroxylase enzyme. In order to investigate whether these B14 positive haplotypes carry the same CYP21 mutation in the various diseases and controls, we have amplified by polymerase chain reaction (PCR) the sections of CYP21B gene which include amino acid positions 172 and 281 where typical mutations are known to occur in 21 hydroxylase deficiency. The presence or absence of the defined mutations was tested by oligonucleotide hybridization using oligonucleotides, labelled with DIG-ddUTP, designed to hybridize with the mutated or with the normal sequence. It was found that regardless of whether the subject tested was a patient or a healthy control the mutation at position 281 was found in all cases carrying HLA-B14, DR1 haplotype. Interestingly, this mutation does not seem to be in association with HLA-B14, DR7 haplotype. These findings suggest that CYP21 gene plays a role in all these differing diseases although it must be stressed that there may be alternative explanations for the observed data.
