Noninvasive prenatal detection of sex chromosomal aneuploidiesby sequencing circulating cell-free DNA from maternal plasma
January 1, 2013
MaterniT21 validation for sex chromosome aneuploidy
• MPSS technology for NIPT allows for genome wide analysis, and thus opportunity for expansion to other clinically relevant fetal chromosomal abnormalities, like sex chromosome aneuploidy
• 411 NIPT samples
• 96.2% sensitivity and 99.7% specificity overall (combined SCAs)
• NIPT identification of the most common sex chromosome aneuploidies is possible using cf DNA and massively parallel sequencing with a high detection rate and a low false positive rate (0.3%).
