Sex chromosome aneuploidies
Numerical anomalies of the sex chromosomes.
Compared to the FetalDNA Base, the FetalDNA Base Plus integrates the aneuplodies of the sex chromosomes (anomalies affecting the sex chromosomes X, Y) which can cause language, movement and / or learning difficulties in children.
The most common of this class of aneuploidy is Turner Syndrome or X-linked Monosomy which affects women with only one copy of the X chromosome.
Other aneuplodias found with the FetalDNA Base Plus are the Trisomy of the X chromosome (XXX), the Klinefelter Syndrome and the Jacobs Syndrome.
