AbstractPrenatal diagnosis of sex-linked disorders requires invasive procedures, carrying a risk of miscarriage of up to 1%. Cell-free fetal DNA (cffDNA) present in cell-free DNA (cfDNA) from maternal plasma offers a non-invasive source of fetal genetic material for analysis. Detection of Y-chromosome sequences in cfDNA indicates presence of a male fetus; in the absence of a Y-chromosome signal a female fetus is inferred. We aimed to validate the clinical utility of insertion-deletion polymorphisms (INDELs) to confirm presence of a female fetus using cffDNA.Quantitative real-time PCR (qPCR) for the Y-chromosome-specific sequence,Fetal sex was correctly determined in 77/82 (93.9%) cfDNA samples.We have validated a non-invasive prenatal test to confirm fetal sex as early as 6 gestational weeks using cffDNA from maternal plasma.

Sixty blood samples from pregnant women during gestational weeks 9–28 were investigated. Cell-free fetal DNA was extracted from maternal plasma or serum to be detected by nested PCR for determination of fetal gender. The SRY gene as a marker for fetal Y chromosome was detected in 34/36 women carrying a male fetus. In 3/24 women carrying female fetuses, the SRY sequence was also detected. Overall, fetal sex was correctly predicted in 91.7% of the cases. Therefore, the new, non-invasive method of prenatal diagnosis of fetal gender for women at risk of producing children with X-linked disorders is reliable, secure, and can substantially reduce invasive prenatal tests.
