Implications of fetoplacental mosaicism on cell‐free DNA testing for sex chromosome aneuploidies
12 Aug 2017
Abstract excerpt
OBJECTIVE: The unique biological behavior of sex chromosomes has implications for cell-free DNA (cfDNA) testing. Our purpose is to predict the (1) false positive/negative rates of cfDNA testing consequent to fetoplacental mosaicism for any sex chromosome aneuploidies (SCA) and (2) positive predictive value (PPV) and negative predictive values of a high-risk and low-risk cfDNA result for any SCA. METHOD: This is a...
