Genes affected

DNAH1 (HGNC:2940): (dynein axonemal heavy chain 1) This gene encodes an inner dynein arm heavy chain that provides structural support between the radial spokes and the outer doublet of the sperm tail. Naturally occurring mutations in this gene are associated with primary ciliary dyskinesia and multiple morphological anomalies of the flagella that result in asthenozoospermia and male infertility. Mice with a homozygous knockout of the orthologous gene are viable but have reduced sperm motility and are infertile. [provided by RefSeq, Feb 2017]

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. 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: "Benign"; Align-GVGD: "Class C25"). ClinVar contains an entry for this variant (Variation ID: 582738). This variant has not been reported in the literature in individuals affected with DNAH1-related conditions. This variant is present in population databases (rs376327672, gnomAD 0.07%). This sequence change replaces aspartic acid, which is acidic and polar, with alanine, which is neutral and non-polar, at codon 830 of the DNAH1 protein (p.Asp830Ala). -

The c.2489A>C (p.D830A) alteration is located in exon 14 (coding exon 13) of the DNAH1 gene. This alteration results from a A to C substitution at nucleotide position 2489, causing the aspartic acid (D) at amino acid position 830 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
