Abstract

Objectives: The aim of the study was to present initial results of non-invasive prenatal diagnosis of common aneuploidies of chromosomes 21, 18 and 13 based on cell-free fetal DNA in maternal serum in high-risk patients, and to compare the results with routine karyotyping. Material and methods: Before the invasive procedure, 10 ml of peripheral blood from 10 patients was collected to isolate cell-free fetal DNA and to perform a non-invasive fetal trisomy test (NIFTY provided by Beijing Genomics Institute, BGI, Shenzen, China). Results: Three out of 10 samples showed an abnormal karyotype in traditional karyotyping. There were 9 conclusive NIFTY results. NIFTY detected 1 out of 2 trisomies 18. The quantity of cell-free fetal DNA in maternal plasma in the second probe with trisomy 18 was unsatisfactory for a conclusive NIFTY result. In 1 case traditional karyotyping revealed mosaicism impossible to detect with NIFTY.
