Applying amplification refractory mutation system technique to detecting cell-free fetal DNA for single-gene disorders purpose.

ABSTRACT: Non-invasive prenatal diagnosis for single-gene disorders (NIPD) is still in development and deserves further study. The advent of next-generation sequencing technology significantly improved the detection of multiple mutations for non-invasive prenatal diagnosis for single-gene disorder purposes. However, bespoke amplicon-based NGS assays are costly. In this study, we developed a new strategy for non-invasive prenatal screening for single-gene disorders based on a capillary electrophoresis (CE) platform using an amplification refractory mutation system (ARMS)-PCR technique. Allele-specific primers for several disease-correlated mutations were designed, and subsequently, sensitivity and specificity assays were conducted. Assays on simulated two-person DNA mixtures showed that three primers
