Processes and Compositions for Methylation-Based Enrichment of Fetal Nucleic Acid From a Maternal Sample Useful for Non-Invasive Prenatal Diagnoses

摘要

Provided are compositions and processes that utilize genomic regions that are differentially methylated between a mother and her fetus to separate, isolate or enrich fetal nucleic acid from a maternal sample. The compositions and processes described herein are particularly useful for non-invasive prenatal diagnostics, including the detection of chromosomal aneuploidies.
