Genet Med 2024; 26:100987. [PMID: 37781900 DOI: 10.1016/j.gim.2023.100987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 09/22/2023] [Accepted: 09/24/2023] [Indexed: 10/03/2023] Open
Abstract
PURPOSE To assess the population-based incidence, prevalence, and age at diagnosis of individuals with 45,X/46,XY mosaicism (and associated variants) and describe the associated mortality pattern. In addition, a systematic literature review of papers providing prevalence data of 45,X/46,XY mosaicism was performed. METHODS A population-based epidemiological study of all individuals diagnosed with 45,X/46,XY mosaicism between 1960 and 2019. Mortality was analyzed using data from the Danish Causes of Death Register. One-hundred randomly age- and sex-matched general population controls per case were identified for comparison. RESULTS One-hundred-thirty-seven males and 46 females with 45,X/46,XY mosaicism were identified. The apparent prevalence was 5.6 per 100,000 liveborn males and 2.1 per 100,000 liveborn females. The incidence of males with 45,X/46,XY increased during the study (P > .0001) but was stable for females (P = .4). Males were significantly older than females when diagnosed (median age = 29.1, interquartile range: 3.4-41.3) years versus 13.3 (interquartile range: 2.1-19.1) years, P = .002). All-cause mortality was doubled in males with 45,X/46,XY (Hazard Ratio = 2.0, 95% confidence interval: 1.2-3.3) and quadrupled in females (Hazard Ratio = 4.0, confidence interval: 2.0-7.9). CONCLUSION The apparent population-based prevalence of males and females with 45,X/46,XY is 5.6 and 2.1 per 100,000 liveborn males and females, respectively. Diagnosis of males with 45,X/46,XY males is increasing. 45,X/46,XY mosaicism is associated with an increased all-cause mortality.

Front Endocrinol (Lausanne) 2023; 14:1160884. [PMID: 37214245 PMCID: PMC10197804 DOI: 10.3389/fendo.2023.1160884] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Accepted: 04/10/2023] [Indexed: 05/24/2023] Open
Abstract
Diagnosis and management of individuals who have differences of sex development (DSD) due to numerical or structural variations of sex chromosomes (NSVSC) remains challenging. Girls who have Turner syndrome (45X) may present with varying phenotypic features, from classical/severe to minor, and some remain undiagnosed. Boys and girls who have 45,X/46,XY chromosomal mosaicism may have Turner syndrome-like features and short stature; therefore, unexplained short stature during childhood requires karyotype analysis in both sexes, particularly if characteristic features or atypical genitalia are present. Many individuals with Klinefelter syndrome (47XXY) remain undiagnosed or are only diagnosed as adults due to fertility problems. Newborn screening by heel prick tests could potentially identify sex chromosome variations but would have ethical and financial implications, and in-depth cost-benefit analyses are needed before nationwide screening can be introduced. Most individuals who have NSVSC have lifelong co-morbidities and healthcare should be holistic, personalized and centralized, with a focus on information, psychosocial support and shared decision-making. Fertility potential should be assessed individually and discussed at an appropriate age. Oocyte or ovarian tissue cryopreservation is possible in some women who have Turner syndrome and live births have been reported following assisted reproductive technology (ART). Testicular sperm cell extraction (TESE) is possible in some men who have 45,X/46,XY mosaicism, but there is no established protocol and no reported fathering of children. Some men with Klinefelter syndrome can now father a child following TESE and ART, with multiple reports of healthy live births. Children who have NSVSC, their parents and DSD team members need to address possibilities and ethical questions relating to potential fertility preservation, with guidelines and international studies still needed.

Abstract
OBJECTIVE To evaluate the growth data, gonadal functions and tumour risk in children with 45, X/46, XY mosaicism. DESIGN We reviewed retrospectively the records of 45 patients with 45, X/46, XY mosaicism or variants presented to our Unit from 1989 to 2019. RESULTS The age at diagnosis ranged from 0.03 to 17.5 years. Twenty-eight patients had genital anomaly, 14 patients had female external genitalia and 3 patients had normal male genitalia. Patients showed normal height under 2 years of age. Mean height standard deviation score (HSDS) of 19 patients diagnosed before 2 years of age was -0.9 ± 0.6 and that of 26 patients diagnosed after 2 years of age was -2.6 ± 1.5. Ten patients diagnosed before 2 years of age showed growth deceleration after 2 years of age (HSDS decreasing from -0.6 ± 0.7 to -1.4 ± 0.9). Twenty-one patients reached adult height (AH). Growth hormone (GH) treatment was initiated in 10 patients. Although AHSDS of GH-treated patients was significantly greater than their mean HSDS before GH therapy (p =.013), it was not significantly different from AHSDS of the untreated group. Seventeen (37.8%) patients exhibited phenotypical features of Turner syndrome (TS) other than short stature. Two patients with genital anomaly had gonadoblastoma and germ cell neoplasia in situ, and one patient with female external genitalia had gonadoblastoma. CONCLUSIONS GH therapy seems to improve AH of patients. Both patients with genital anomaly and female external genitalia have increased risk of germ cell tumours.

Front Endocrinol (Lausanne) 2021; 12:709954. [PMID: 34447353 PMCID: PMC8382946 DOI: 10.3389/fendo.2021.709954] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Accepted: 07/15/2021] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVE Insulin-like factor 3 (INSL3) is produced in the testes and has been proposed as a circulating biomarker of Leydig cell capacity, but remains undescribed in 45,X/46,XY mosaicism. The aim was to examine serum concentrations and gonadal expression of INSL3 in 45,X/46,XY mosaicism. METHODS Retrospectively collected data from medical records, gonadal tissue samples, and prospectively analyzed serum samples from eighteen male patients with 45,X/46,XY mosaicism (one prepubertal, four testosterone-treated, 13 untreated) were included. Biochemical, clinical, and histological outcomes were evaluated according to serum INSL3 concentrations, quantified by LC-MS/MS methodology, and gonadal INSL3 immunohistochemical expression. RESULTS Serum INSL3 concentrations spanned from below to above the reference range. In untreated patients, the median serum INSL3 SD score was -0.80 (IQR: -1.65 to 0.55) and no significant difference was observed between INSL3 and testosterone. There was no clear association between serum INSL3 and External Genitalia Score at diagnosis, spontaneous puberty, or sperm concentration. INSL3 and CYP11A1 expression overlapped, except for less pronounced INSL3 expression in areas with severe Leydig cell hyperplasia. No other apparent links between INSL3 expression and histological outcomes were observed. CONCLUSIONS In this pilot study, serum INSL3 concentrations ranged and seemed independent of other reproductive hormones and clinical features in males with 45,X/46,XY mosaicism. Discordant expression of INSL3 and CYP11A1 may explain low INSL3 and normal testosterone concentrations in some patients. Further studies are needed to elucidate the divergence between serum INSL3 and testosterone and the potential clinical use of INSL3.

Abstract
BACKGROUND 45,X/46,XY mosaicism is a rare chromosomal abnormality with a wide range of phenotypes in both males and females, from normal individuals with different degrees of genital ambiguity to those who show signs of Turner’s syndrome. More rarely, cases of 45,X/46,XY mosaicism with a normal-appearing male phenotype are not found until a chromosome test is performed to investigate the cause of male infertility.
CASE SUMMARY In this study, a 29-year-old male patient with complete azoospermia is reported. Chromosomal analyses of his lymphocytes revealed the karyotype 45,X[93%]/46,X,+mar(Y)[7%]. In addition, Y chromosome-specific markers, such as SRY, ZFY, AZFa, AZFb and AZFc, were not observed in his blood DNA according to multiplex polymerase chain reaction test. A literature review identified several 45,X/46,XY cases with a normal-appearing male phenotype, most of whom were diagnosed during infertility investigation. However, the present case is the first SRY-negative 45,X/46,XY male case diagnosed during a premarital medical examination.
CONCLUSION This finding further suggests that sex determination is a complex process regulated by multiple genetic and environmental factors.

Abstract
Chromosomal abnormality is a primary genetic factor that lead to azoospermia and male infertility. Here, we report the cases of two brothers with primary infertility, whose chromosomes displayed a balanced translocation, and their karyotypes were 46,Y, t(X; 1) (q28; q21). Both presented an azoospermia phenotype without abnormal clinical symptoms. Their mother's karyotype was 46,X, t(X; 1) (q28; q21), and their father's chromosome karyotype was 46,XY. No abnormal changes were noted in the copy number of chromosome fragments in the whole genome. This study is the first to report showing that 46,Y, t(X; 1) (q28; q21) chromosomal abnormalities are associated with azoospermia.

Abstract
Sex chromosome abnormality (SCA) is one of the major causes of male spermatogenesis dysfunction. In our study, we sought to investigate the novel X chromosome inversion leading to severe oligozoospermia. Here, we report two brothers with severe oligozoospermia without any other abnormal clinical phenotype. The chromosome karyotypes in peripheral blood of both brothers were 46, Y, inv (X) (p22.3, q22), and no Y chromosome microdeletion was found. The karyotype of their mother was 46, X, inv (X) (p22.3, q22) and that of their father was 46, XY. This is the first report in China that X chromosomal inversion, 46, Y, inv (X) (p22.3, q22), is associated with severe oligozoospermia. This inversion may be a direct genetic risk factor for spermatogenesis.

Abstract
CONTEXT Larger studies on outcomes in males with 45,X/46,XY mosaicism are rare. OBJECTIVE To compare health outcomes in males with 45,X/46,XY diagnosed as a result of either genital abnormalities at birth or nongenital reasons later in life. DESIGN A retrospective, multicenter study. SETTING Sixteen tertiary centers. PATIENTS OR OTHER PARTICIPANTS Sixty-three males older than 13 years with 45,X/46,XY mosaicism. MAIN OUTCOME MEASURES Health outcomes, such as genital phenotype, gonadal function, growth, comorbidities, fertility, and gonadal histology, including risk of neoplasia. RESULTS Thirty-five patients were in the genital group and 28 in the nongenital. Eighty percent of all patients experienced spontaneous pubertal onset, significantly more in the nongenital group (P = 0.023). Patients were significantly shorter in the genital group with median adult heights of 156.7 cm and 164.5 cm, respectively (P = 0.016). Twenty-seven percent of patients received recombinant human GH. Forty-four patients had gonadal histology evaluated. Germ cells were detected in 42%. Neoplasia in situ was found in five patients. Twenty-five percent had focal spermatogenesis, and another 25.0% had arrested spermatogenesis. Fourteen out of 17 (82%) with semen analyses were azoospermic; three had motile sperm. CONCLUSION Patients diagnosed as a result of genital abnormalities have poorer health outcomes than those diagnosed as a result of nongenital reasons. Most patients, however, have relatively good endocrine gonadal function, but most are also short statured. Patients have a risk of gonadal neoplasia, and most are azoospermic, but almost one-half of patients has germ cells present histologically and up to one-quarter has focal spermatogenesis, providing hope for fertility treatment options.

Abstract
BACKGROUND The aim of this study was to review the growth data, gonadal function and tumour risk of children and adolescents with 45,X/46,XY mosaicism who presented to a single centre in China. METHODS We conducted a retrospective review of the records of 32 patients with 45,X/46,XY mosaicism or variants who were hospitalized from August 2005 to September 2018. The main outcomes measured were growth data, genital phenotype, gonadal function, gonadal position, and histological results. RESULTS A total of 32 patients were included. The age at diagnosis ranged from 0.6 to 16.3 years. Nineteen patients exhibited ambiguous genitalia, 12 had short stature, and 1 showed a lack of breast development. Seventeen patients were raised as males, and 15 were raised as females. The external masculinisation score (EMS) of patients raised as male was 4.5 (1~12) [median (range)]. The EMS of the females was 0 (0~1.5) [median (range)]. Patients showed normal heights under 2 years old, with a height SDS of 0 (- 1.5~1.4) [median (range)]. Growth appeared to decelerate after age 2 years, with SDS decreased to - 2.8 (- 3.0~ - 0.9) [median (range)]. The percentage of short stature was higher in females than in males (76.9% vs 50.0%). Twenty-five patients had gonadal pathological results. Complete gonadal dysgenesis (CGD) and mixed gonadal dysgenesis (MGD) were the most common pathogenic subtypes, accounting for 48.0 and 36.0%, respectively. Ovotesticular tissue was observed in only 4.0% of patients. Gonadoblastoma and positive OCT3/4 results were found in 18.8% of gonads in children over 2 years of age. Palpable gonads accounted for 50% of these. All patients who had gonadoblastoma were raised as females. CONCLUSIONS Patients with 45,X/46,XY might have normal heights until 2 years old. Growth decelerations after 2 years of age were common. Patients who are being raised as females seemed to be shorter than males. CGD and MGD were the most common gonadal pathogenic subtypes. The tumour risk is high in these patients, even in palpable gonads and female patients.

45,X/46,XY Mosaicism and Normozoospermia in a Patient with Male Phenotype. Case Rep Med 2019; 2019:2529080. [PMID: 30805004 PMCID: PMC6360613 DOI: 10.1155/2019/2529080] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2018] [Accepted: 12/20/2018] [Indexed: 12/24/2022] Open
Abstract
The phenotypic spectrum of 45,X/46,XY mosaic males varies greatly. Previous reports have only described cases with either oligozoospermia, growth retardation, or elevated gonadotropins. However, the present case presented with normozoospermia, and normal height, sperm DNA fragmentation index (DFI), and gonadotropins. The male and his spouse were referred to The Fertility Clinic, Skive Regional Hospital, due to 2 years of infertility. After failure of several attempts of assisted reproductive treatment (ART), the male underwent genetic analysis. Conventional karyotyping in peripheral lymphocytes yielded a low-grade 45,X/46,XY mosaicism, confirmed by fluorescence in situ hybridization (FISH) showing 6% 45,X cells. A FISH test performed on interphase nuclei from buccal mucosal cells yielded one cell with only one X-signal (0.6%), explaining the normal phenotype of the patient, but not the infertility. FISH test for sperm aneuploidy showed normal range parameters, except for a 10-fold elevated gonosomal nullisomy rate (2.1%). Hence, germinal mosaicism may be an explanation of the infertility of the case. Increased sex nullisomy levels may reflect an aberrant testicular environment compromising fertility even though sperm euploidy rates and other sperm parameters do not preclude a successful treatment with ART. Based on these results, the couple decided to use donor semen for their subsequent intrauterine insemination treatment and obtained a successful pregnancy.

Should 45,X/46,XY boys with no or mild anomaly of external genitalia be investigated and followed up? Eur J Endocrinol 2018; 179:181-190.

Abstract
OBJECTIVE Few studies of patients with a 45,X/46,XY mosaicism have considered those with normal male phenotype. The purpose of this study was to evaluate the clinical outcome of 45,X/46,XY boys born with normal or minor abnormalities of external genitalia, notably in terms of growth and pubertal development. METHODS Retrospective longitudinal study of 40 patients followed between 1982 and 2017 in France. RESULTS Twenty patients had a prenatal diagnosis, whereas 20 patients had a postnatal diagnosis, mainly for short stature. Most patients had stunted growth, with abnormal growth spurt during puberty and a mean adult height of 158 ± 7.6 cm, i.e. -2.3 DS with correction for target height. Seventy percent of patients presented Turner-like syndrome features including cardiac (6/23 patients investigated) and renal malformations (3/19 patients investigated). Twenty-two patients had minor abnormalities of external genitalia. One patient developed a testicular embryonic carcinoma, suggesting evidence of partial gonadal dysgenesis. Moreover, puberty occurred spontaneously in 93% of patients but 71% (n = 5) of those evaluated at the end of puberty presented signs of declined Sertoli cell function (low inhibin B levels and increased FSH levels). CONCLUSION This study emphasizes the need to identify and follow-up 45,X/46,XY patients born with normal male phenotype until adulthood, as they present similar prognosis than those born with severe genital anomalies. Currently, most patients are diagnosed in adulthood with azoospermia, consistent with our observations of decreased testicular function at the end of puberty. Early management of these patients may lead to fertility preservation strategies.
