Abstract: The present disclosure provides methods for determining the ploidy status of a chromosome in a gestating fetus from genotypic data measured from a mixed sample of DNA comprising DNA from both the mother of the fetus and from the fetus, and optionally from genotypic data from the mother and father. The ploidy state is determined by using a joint distribution model to create a plurality of expected allele distributions for different possible fetal ploidy states given the parental genotypic data, and comparing the expected allelic distributions to the pattern of measured allelic distributions measured in the mixed sample, and choosing the ploidy state whose expected allelic distribution pattern most closely matches the observed allelic distribution pattern. The mixed sample of DNA may be preferentially enriched at a plurality of polymorphic loci in a way that minimizes the allelic bias, for example using massively multiplexed targeted PCR.

Abstract: The present disclosure provides methods for determining the status of an allograft within a transplant recipient from genotypic data measured from a mixed sample of DNA comprising DNA from both the transplant recipient and from the donor. The mixed sample of DNA may be preferentially enriched at a plurality of polymorphic loci in a way that minimizes the allelic bias, for example using massively multiplexed targeted PCR.

Abstract: The invention provides improved methods, compositions, and kits for detecting ploidy of chromosome regions, e.g. for detecting cancer or a chromosomal abnormality in a gestating fetus. The methods can utilize a set of more than 200 SNPs that are found within haploblocks and can include analyzing a series of target chromosomal regions related to cancer or a chromosomal abnormality in a gestating fetus. Finally the method may use knowledge about chromosome crossover locations or a best fit algorithm for the analysis. The compositions may comprise more than 200 primers located within haplotype blocks known to show CNV.
