Abstract: The invention provides methods for assessment of risk for genetic conditions using target-enriched multiplexed parallel analysis, for example fetal risk for genetic conditions in prenatal testing. The methods of the invention utilize Target Capture Sequences (TACS) to thereby enrich for target sequences of interest, followed by massive parallel sequencing and statistical analysis of the enriched population. The methods of the disclosure can be used to determine carrier status of inheritable genetic abnormalities associated with genetic conditions and from this information the fetal risk of inheriting the genetic condition can be determined. Kits for carrying out the methods of the invention are also provided.

Abstract: The invention provides methods for assessment of fetal DNA samples using target-enriched multiplexed parallel analysis. The methods of the invention utilize Target Capture Sequences (TACS) to thereby enrich for target sequences of interest, followed by massive parallel sequencing and statistical analysis of the enriched population. The methods can be used with fetal or embryonic DNA samples, for example for the detection of the presence of genetic abnormalities, e.g., for purposes of IVF Pre-implantation Genetic Screening (PGS) and Diagnosis (PGD). Kits for carrying out the methods of the invention are also provided.
