Abstract

Objective: Analysis of prenatally diagnosed sex chromosome aneuploidies and disorders of sex development (DSDs).

Methods: This study includes a retrospective data analysis of 46 prenatally detected sex chromosome aneuploidies and one case of 46,XY DSD diagnosed during an 11-year period (2002–2012) at our department.

Results: Of the 46 sex chromosome aneuploidies, 29 cases (63.0%) were in the group of a selected population of women according to abnormal first-/second-trimester ultrasound and 17 (37.0%) cases in an unselected population of women who underwent fetal karyotyping because of advanced maternal age. The most common aneuploidy was Turner syndrome in full and mosaic form (50%). Complete androgen insensitivity syndrome was diagnosed in the case of 46,XY DSD.

Conclusions: Sex chromosome aneuploidies must be taken into consideration if, in the first or second trimester, abnormalities are revealed on ultrasound, mainly Turner syndrome in full or mosaic form and 47,XYY.
