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]

Primary ciliary dyskinesia Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Sep 01, 2021 | This sequence change replaces isoleucine with methionine at codon 700 of the DNAH8 protein (p.Ile700Met). The isoleucine residue is highly conserved and there is a small physicochemical difference between isoleucine and methionine. This variant is present in population databases (rs758338554, ExAC 0.03%). This variant has not been reported in the literature in individuals affected with DNAH8-related conditions. 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. - |
