We conclude that 95% of 45,X/46,XY fetuses will have normal male genitalia, although there will also be a significant risk (27%) for abnormal gonadal histology. Long-term follow-up studies of prenatally diagnosed cases of 45,X/46,XY mosaicism are needed to study, without ascertainment bias, stature, pubertal development, tumor risk, and fertility.Cited by: 236

45,X/46,XY mosaicism, also known as X0/XY mosaicism and mixed gonadal dysgenesis, is a rare disorder of sex development in humans associated with sex chromosome aneuploidy and mosaicism of the Y chromosome. This is called a mosaic karyotype because, like tiles in mosaic floors or walls, there is more than one type of cell.Specialty: Obstetrics and gynaecology, endocrinology, …

Abstract. The prognosis for 45,X/46,XX mosaicism diagnosed prenatally has yet to be established. We report our experience with 12 patients in whom prenatal diagnosis of 45,X/46,XX mosaicism was detected by amniocentesis for advanced maternal age or decreased maternal serum alpha-feto protein and compared them with 41 45,X/46,XX patients diagnosed postnatally.Cited by: 84

what we call 45,X/46,XY: the variations are very complex, and the actual result in living individuals is often not a simple picture of having some of their cells with 45 chromosomes [one of which is an X] and the rest with 46 chromosomes [one an X and one ... including doctors and support groups, use terms that are now out of use.

The purpose of this study was to assess the benefit of ultrasound evaluation for fetuses with prenatally diagnosed 45,X/46,XY mosaicism. The charts of all patients who underwent chorionic villus sampling and/or amniocentesis between 1 March 1990 and 31 October 1995 were screened for …Cited by: 7

Given 90% of 45,X/46,XY fetuses ascertained at amniocentesis having a normal male phenotype at birth (159), this is the most common phenotype for this mosaicism. That 45,X/46,XY neonates with genital ambiguity are recognized more often simply reflects biases of ascertainment.

Dec 27, 2019 · 45,X/46,XY mosaicism is commonly observed in patients with ambiguous genitalia caused by gonadal dysgenesis. Based on the gonadal histology, 45,X/46,XY mosaicism and its variants are classified into 3 pathological groups. When both gonads are streak gonads, the patient has a female phenotype and features of Turner syndrome (TS).

A total of 54 cases with prenatal diagnosis of 45,X/46,XY mosaicism was reviewed. Of 47 cases with information on phenotypic outcome, 42 cases (89·4 percent) were reported to be associated with a grossly normal male phenotype. Three cases (6·4 percent) were diagnosed as having mixed gonadal dysgenesis with internal asymmetrical gonads.Cited by: 86

Mar 12, 2018 · In 45,X/46,XY cases, both 45,X and 46,XY cell lines are seen. Various distributions of both cell lines can reflect a wide range of phenotypes that may be the most comprehensive evaluation in infertile males with 45,X/46,XY karyotype. It assumes that karyotyping as a main diagnostic test can enable us to find these rare cases.Cited by: 4
