Invitae RCV000526889 SCV000660277 uncertain significance Spermatogenic failure 18; Ciliary dyskinesia, primary, 37 2022-10-17 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 2098 of the DNAH1 protein (p.Arg2098His). This variant is present in population databases (rs373906923, gnomAD 0.2%). This variant has not been reported in the literature in individuals affected with DNAH1-related conditions. ClinVar contains an entry for this variant (Variation ID: 478476). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt DNAH1 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.

GeneDx RCV001755922 SCV001986768 uncertain significance not provided 2021-04-14 criteria provided, single submitter clinical testing In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
PreventionGenetics, part of Exact Sciences RCV003962622 SCV004784992 likely benign DNAH1-related condition 2022-12-01 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).
