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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

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 output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The lysine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 567451). This variant has not been reported in the literature in individuals affected with DNAH1-related conditions. This variant is present in population databases (rs201610799, gnomAD 0.04%). This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 1370 of the DNAH1 protein (p.Glu1370Lys). -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The DNAH1 c.4108G>A variant is predicted to result in the amino acid substitution p.Glu1370Lys. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.037% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/3-52392595-G-A). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
