Abstract: Methods and systems for determining copy number variants are disclosed. An example method can comprise applying a sample grouping technique to select reference coverage data, normalizing sample coverage data comprising a plurality of genomic regions, and fitting a mixture model to the normalized sample coverage data based on the selected reference coverage data. An example method can comprise identifying one or more copy number variants (CNVs) according to a Hidden Markov Model (HMM) based on the normalized sample coverage data and the fitted mixture model. An example method can comprise outputting the one or more copy number variants.

Abstract: Methods and systems for generating and analyzing genetic variant-phenotype association results are disclosed.

Abstract: Methods and systems for detecting abnormal karyotypes are disclosed. An example method can comprise determining read coverage data, allele balance distributions of heterozygous SNPs, and chromosomal segments where heterozygosity is not observed. The methods and systems can then determine one or more metrics which can be indicative of abnormal karyotype(s).
