Abstract:Runs of homozygosity (ROH) are uninterrupted contiguous regions within the genome exhibiting allelic homozygosity (alleles are inherited from the same parent). Genome-wide analyses consistently demonstrate that megabase-scale ROH are ubiquitous in humans, reflecting individual demographic history. The number and length of ROH correlate increasingly with the degree of consanguinity and can be associated with genetic diseases in both inbred and outbred individuals. Genomic imprinting and uniparental disomy (UPD)… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
