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]

This sequence change creates a premature translational stop signal (p.Asp638Glyfs*10) in the DNAH1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DNAH1 are known to be pathogenic (PMID: 27573432, 27798045). This variant is present in population databases (rs557979163, gnomAD 0.03%). 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: 478375). For these reasons, this variant has been classified as Pathogenic. -
