Genes affected
DNAH8 (HGNC:2952): (dynein axonemal heavy chain 8) The protein encoded by this gene is a heavy chain of an axonemal dynein involved in sperm and respiratory cilia motility. Axonemal dyneins generate force through hydrolysis of ATP and binding to microtubules. [provided by RefSeq, Jan 2012]

This sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 2372 of the DNAH8 protein (p.Met2372Val). This variant is present in population databases (rs769036544, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with DNAH8-related conditions. ClinVar contains an entry for this variant (Variation ID: 407276). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
