Genes affected
DNAJB13 (HGNC:30718): (DnaJ heat shock protein family (Hsp40) member B13) This gene encodes a member of the heat shock protein 40 co-chaperone family which is produced in large amounts in the testis and is located on the radial spokes of the axoneme in human sperm flagella and other flagellar structures. The encoded protein associates with the sperm annulus, as part of the septin complex, through direct interaction with septin 4, during sperm terminal differentiation. Naturally occurring mutations in this gene are associated with primary ciliary dyskinesia and male infertility. [provided by RefSeq, Apr 2017]

This sequence change replaces methionine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 278 of the DNAJB13 protein (p.Met278Thr). This variant is present in population databases (rs754776389, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with DNAJB13-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: "Probably Damaging"; 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. -
