- Abstract
Fetal structural anomalies and birth defects are primarily caused by genetic variants such as chromosomal number abnormalities, copy number variations (CNV), single nucleotide variants (SNV), and small insertions and deletions (indel). Whole-genome sequencing (WGS) based on next-generation sequencing (NGS) as an emerging technology for genetic disease diagnosis can detect the aforementioned types of variants. In recent years, high-depth WGS (> 30×) for prenatal diagnosis has also become available, and proved to be practical for unraveling the genetic etiology of fetal developmental abnormalities. To facilitate clinical practice, test development and preliminary implementation of WGS for diagnosing fetal structural anomalies, we have formulated a consensus over the application of WGS in prenatal diagnosis by compiling previously published consensuses, guidelines, and research findings to provide a guidance on data analysis, reporting recommendations, and consultation of prenatal WGS results.
