無(wú)創(chuàng)產(chǎn)前基因檢測(cè)雙胎21、18和13-三體綜合征的應(yīng)用研究
[Abstract]:Objective to investigate the clinical feasibility of non-invasive prenatal gene detection of (NIPT) twins 21 ~ 18 and 13-trisomy syndrome. Methods Twin pregnant women were selected from August 2012 to November 2014 in the Fetal Medical Center of the third affiliated Hospital of Guangzhou Medical University or the obstetrical center of Foshan Maternal and Child Health Hospital. There were 215 pregnant women who agreed to NIPT test. Maternal plasma free DNA sequencing was used to detect the risk of 21 ~ 18 and 13-trisomy syndrome. Chromosome karyotype examination is the gold standard to verify the accuracy of NIPT test, and neonatal physical examination is the auxiliary test standard. Results the results of NIPT showed that there was a high risk of 21 trisomy syndrome, and all of them were confirmed as 21 trisomy syndrome by chromosome karyotype. The results of NIPT in the remaining 212 cases showed low risk and no abnormality was found in chromosome karyotype or neonatal physical examination. In this study, the accuracy of NIPT in the detection of twin 21 ~ (18) and 13-trisomy syndrome was 100, and the incidence of invasive prenatal diagnosis was reduced. Conclusion NIPT is a new choice for prenatal screening of twin twins with 21, 18 and 13-trisomy syndrome, and it is feasible to apply it to clinical practice.
