Autosomal heterozygosity
WebHeterozygote Advantage. Heterotic balance (heterozygous advantage) polymorphisms develop when the fitness of heterozygotes is higher than the fitness of both homozygotes in a given population. A classic case of balanced polymorphism in human populations is sickle cell anemia. A mutation in the hemoglobin gene (β S) leads to an alteration in ... WebThe .gov means it's official.

WebOct 8, 2009 · A fifth subunit, p40(phox), plays an important role in phagocytosis-induced superoxide production via a phox homology (PX) domain that binds to phosphatidylinositol 3-phosphate (PtdIns(3)P). We report the first case of autosomal recessive mutations in NCF4, the gene encoding p40(phox), in a boy who presented with granulomatous colitis. WebThe threshold level for autosomal heterozygosity rate depends upon visual inspection of the clustering of autosomal heterozygosity rates for all samples in a distribution plot. Personally, we would recommend a threshold level of 4 standard deviations (4SD) away from the mean of autosomal heterozygosity rate in a dataset.

WebO'Neill et al. (1996) mapped a locus for autosomal dominant late-onset progressive nonsyndromic hearing loss, designated DFNA10, to chromosome 6q22.2-q23.3 on the basis of linkage analysis in a large multigenerational family from the U.S. The markers D6S472 and D6S407 yielded 2-point lod scores of 4.44 and 4.0 at theta = 0, respectively.
