Universal noninvasive prenatal diagnosis for monogenic disorders using cell-free plasma DNA.

ABSTRACT:

Background

Noninvasive prenatal screening for aneuploidies and microdeletion/microduplication syndromes (MMS) has gained widespread clinical application. However, the development of noninvasive prenatal diagnosis for monogenic disorders (NIPT-M) has progressed slower. Existing NIPT-M approaches often require specialized designs, are limited to a narrow range of genes, or are expensive and impractical for clinical implementation.

Methods

We present HaploNIPD, a universal haplotype-based approach for NIPT-M, utilizing a targeted capture panel that includes 120,000 selected single-nucleotide polymorphisms. Maternal cell-free DNA (cfDNA) and genomic DNA (gDNA) from family members were targeted captured and massively parallel sequenced. Parental haplotypes were phased, and fetal
