We report on the prenatal diagnosis of a fetus with 46,XY and 46,XX cell lines with a normal male phenotype. Cytogenetic and molecular studies ruled out the possibility of maternal cell contamination and showed that all the X chromosomes present in both fetal cell lines were derived from a single ma

β¦ Synopsis
We report on a second 46,XX male with microphthalmia with linear skin defects (MLS) syndrome. In addition to microphthalmia and linear skin streaks, he had a secundum ASD, hypospadias with chordee, anal fistula, and agenesis of corpus callosum with colpocephaly. Biopsy of a linear streak showed smooth muscle hamartomata rather than the presumed dermal aplasia. Detailed ophthalmologic examination did not show retinal lacunae typical of Aicardi syndrome. DNA studies with distal Xp specific probes indicated a deletion in one X chromosome and fluorescence in situ hybridization (FISH) studies with X-and Y-specific probes demonstrated the presence of a derivative X chromosome from an X;Y translocation.
