As part of the ongoing PPB Speaker Series, Dr. Arthur Beaudet will discuss the protocol for single fetal cell (SFC) testing he and his team have implemented. This protocol uses magnetic-activated cell sorting to enrich for fetal trophoblasts, single cell picking, whole genome amplification, genotyping, and low-coverage whole genome sequencing for copy number variant analysis.
Genetic analysis of fetal cells from maternal circulation might provide a breakthrough in prenatal diagnosis. SFC testing has the potential to provide high positive and negative predictive values. It also has the potential to detect all genetic abnormalities detectable by amniocentesis or chorionic villus sampling. Dr. Beaudet and his team of researchers have completed two pilot validation studies demonstrating the feasibility of using SFC testing as a novel form of prenatal diagnosis.
