Unilateral true hermaphrodite with 46,XX/46,XY dispermic chimerism.
A 13 year old female presented with ambiguous external genitalia, right inguinal ovotestis, left ovary, apparently normal Mullerian system, and absent Wolffian system. Cultured lymphocytes showed a 46,XX/46,XY karyotype. Histopathology of the gonads confirmed true hermaphroditism. The presence of two genetically different erythrocyte populations was observed. The findings suggested that the pat...
متن کاملPrenatal diagnosis and genetic analysis of a fetus with 47,XX,+21/46,XX mosaicism and XX/XY chimerism.
Prenatal diagnosis of simultaneous occurrence of chimerism and autosomal mosaicism is extremely rare. We report the prenatal diagnosis and genetic analysis of a fetus in a twin pregnancy with mosaic 47,XX,+21/46,XX with chimeric XX/XY. A 36-year-old, para 1, woman was referred for genetic counseling at 20 weeks' gestation because of abnormal karyotype (47,XX,+21/46,XX) in one fetus in a twin pr...
متن کاملPresumptive 46,XX-46,XY-47,XXY mosaicism in a hermaphrodite.
Contrary to the expected XX/XY sex chromosome complements in hermaphroditism, a variety of karyotypes have been reported instead. Dewhurst et al. (1965) summarized from published reports the karyotypic findings in 27 patients with convincing evidence ofhermaphroditism, as follows: 46,XX (17); 46,XY (2); 46,XX/47,XXX (1); 46,XX/46,XX + Frag (1); 46,XX/46,XY (3); 46,XX/47,XXY/ 49,XXYYY (1); 46,XX...
متن کاملTrizygotic dichorionic triplets with 46,XX/46,XY chimerism in both fetuses of the monochorionic pair.
Monochorionic fetuses are traditionally thought of as monozygotic (MZ), arising from a single embryo that splits during early embryogenesis. With rare exception, they typically exhibit the same genotype and the same gender. However, several recent reports have documented that monochorionicity does not always indicate monozygosity (Souter et al., 2003). At least 14 such cases have been reported ...
