Patent number: 9163282Abstract: 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: GrantFiled: March 8, 2013Date of Patent: October 20, 2015Assignee: NATERA, INC.Inventors: Matthew Rabinowitz, George Gemelos, Milena Banjevic, Allison Ryan, Zachary Demko, Matthew Hill, Bernhard Zimmermann, Johan Baner

Publication number: 20140256569Abstract: A system and method for determining the genetic data for one or a small set of cells, or from fragmentary DNA, where a limited quantity of genetic data is available, are disclosed. Genetic data for the target individual is acquired and amplified using known methods, and poorly measured base pairs, missing alleles and missing regions are reconstructed using expected similarities between the target genome and the genome of genetically related subjects. In accordance with one embodiment of the invention incomplete genetic data is acquired from embryonic cells, fetal cells, or cell-free fetal DNA isolated from the mother's blood, and the incomplete genetic data is reconstructed using the more complete genetic data from a larger sample diploid cells from one or both parents, with or without genetic data from haploid cells from one or both parents, and/or genetic data taken from other related individuals.Type: ApplicationFiled: May 23, 2014Publication date: September 11, 2014Applicant: Natera, Inc.Inventors: Matthew Rabinowitz, Milena Banjevic, Zachary Demko, David Johnson

Publication number: 20130261004Abstract: 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: March 18, 2013Publication date: October 3, 2013Applicant: Natera, Inc.Inventors: Allison Ryan, Styrmir Sigurjonsson, Milena Banjevic, George Gemelos, Matthew Hill, Johan Baner, Matthew Rabinowitz, Zachary Demko
