Many factors such as genetic, developmental and hormonal are involved in mammalian sex determination. The relative importance and the mutual interactions among those factors are obscure. Study of cytogenetic mosaicism involving sex chromosomes may help to further unravel the mysterious process. We report a fetus with a mosaic karyotype, 45,X/46,X,idic(Y)(qter-p11.3::p11.3-qter), with unambiguous male external genitalia and a defect in the interventricular septum of the heart. Genotype of this fetus was extensively studied by technologies including sequencing of SRY (sex-determining region on the Y chromosome) gene, G-banding, FISH (fluorescence in situ hybridization) and SKY (spectral karyotyping). A markedly higher percentage of Y-containing cells was observed in the gonads (55%) than in the amniotic fluid (17%) and placental villi (11%), which was considered to be the major reason why the fetus did not have ambiguous genitalia.
