Invitae RCV000529121 SCV000623979 uncertain significance Primary ciliary dyskinesia 2021-08-28 criteria provided, single submitter clinical testing This sequence change replaces threonine with methionine at codon 3562 of the DNAH8 protein (p.Thr3562Met). The threonine residue is weakly conserved and there is a moderate physicochemical difference between threonine and methionine. This variant is present in population databases (rs373914023, ExAC 0.1%). 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: 454537). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0". The methionine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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.
Ambry Genetics RCV003243172 SCV003942551 likely benign Inborn genetic diseases 2023-06-12 criteria provided, single submitter clinical testing This alteration is classified as likely benign based on a combination of the following: population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
PreventionGenetics, part of Exact Sciences RCV003960244 SCV004781296 likely benign DNAH8-related condition 2022-04-14 criteria provided, single submitter clinical testing This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications).
