Runs of homozygosity
Webb26 maj 2024 · Long runs of homozygosity (ROHs) are frequently identified in cases interrogated by single nucleotide polymorphism (SNP) array. Presence of ROHs may be because of parental relatedness, chromosomal recombination or rearrangements and provides important clues regarding ancestral homozygosity, consanguinity or … Webb30 okt. 2016 · Runs of homozygosity (ROH), uninterrupted stretches of homozygous genotypes resulting from parents transmitting identical haplotypes to their offspring, have emerged as informative genome-wide estimates of autozygosity (inbreeding). We used genomic profiles based on 698 K single nucleotide polymorphisms (SNPs) from nine …

Variant calls that are homozygous for the alternate allele in all samples are used for ROH estimation, and the remaining variant calls within the captured regions (light ticks) are used to estimate ROH.
Webb2 maj 2024 · runs of homozygosity (ROH), These provide a broad 'summary' of the data and allow us to appropriately set thresholds for quality control. It would be wrong, for example, to run a statistical test on a genotype with high missingness because the resulting P value would be misleading and could lead to erroneous conclusions from the …
