ClinVar
Submissions by phenotype
not specified Uncertain:1
The c.10672A>G (p.N3558D) alteration is located in exon 72 (coding exon 71) of the DNAH8 gene. This alteration results from a A to G substitution at nucleotide position 10672, causing the asparagine (N) at amino acid position 3558 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Primary ciliary dyskinesia Uncertain:1
This sequence change replaces asparagine, which is neutral and polar, with aspartic acid, which is acidic and polar, at codon 3558 of the DNAH8 protein (p.Asn3558Asp). This variant is present in population databases (rs746067892, gnomAD 0.09%). 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: 640492). 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: "Tolerated"; 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. -
