Abstract

In recent years, a shift in prenatal screening methods has been observed, moving away from traditional approaches such as ultrasound and maternal serologic markers towards the utilization of noninvasive prenatal testing (NIPT) based on cfDNA extracted from peripheral blood. This cutting-edge technology has established itself as the primary screening method, attributed to its superior detection rate and reduced false-positive rate. Although NIPT predominantly focuses on screening for chromosomal abnormalities, it currently does not encompass the identification of single-gene disorders. Considering that single-gene disorders contribute significantly to birth defects, accounting for 7.5% to 12% of cases, it becomes imperative to integrate screening for single-gene disorders into the birth defect prevention and control system. This study aims to provide a succinct overview of the recent advancements in NIPT specifically tailored for monogenic disorders.

利用母体血浆中的 cfDNA 对胎儿外显子进行无创筛查。
近年来,产前筛查方法发生了转变,从超声波和母体血清学标记等传统方法转向使用基于外周血中提取的 cfDNA 的无创产前检测(NIPT)。这项尖端技术因其卓越的检测率和较低的假阳性率,已成为主要的筛查方法。虽然 NIPT 主要侧重于筛查染色体异常,但目前还不包括单基因疾病的鉴定。考虑到单基因遗传病在出生缺陷中的比例高达 7.5% 至 12%,将单基因遗传病筛查纳入出生缺陷防控体系势在必行。本研究旨在简明扼要地概述专门针对单基因疾病的 NIPT 的最新进展。
