Publication number: 20190256906Abstract: 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.Type: ApplicationFiled: April 30, 2019Publication date: August 22, 2019Applicant: Natera, Inc.Inventors: Matthew RABINOWITZ, George GEMELOS, Milena BANJEVIC, Allison RYAN, Zachary DEMKO, Matthew HILL, Bernhard ZIMMERMANN, Johan BANER

Publication number: 20190194743Abstract: Methods for non-invasive prenatal paternity testing are disclosed herein. The method uses genetic measurements made on plasma taken from a pregnant mother, along with genetic measurements of the alleged father, and genetic measurements of the mother, to determine whether or not the alleged father is the biological father of the fetus. This is accomplished by way of an informatics based method that can compare the genetic fingerprint of the fetal DNA found in maternal plasma to the genetic fingerprint of the alleged father.Type: ApplicationFiled: February 27, 2019Publication date: June 27, 2019Applicant: Natera, Inc.Inventors: Allison RYAN, Styrmir SIGURJONSSON, Milena BANJEVIC, George GEMELOS, Matthew HILL, Johan BANER, Matthew RABINOWITZ, Zachary DEMKO
