Genes affected

DNAH8 (HGNC:2952): (dynein axonemal heavy chain 8) The protein encoded by this gene is a heavy chain of an axonemal dynein involved in sperm and respiratory cilia motility. Axonemal dyneins generate force through hydrolysis of ATP and binding to microtubules. [provided by RefSeq, Jan 2012]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.3014G>A (p.G1005E) alteration is located in exon 22 (coding exon 21) of the DNAH8 gene. This alteration results from a G to A substitution at nucleotide position 3014, causing the glycine (G) at amino acid position 1005 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.

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 (SIFT, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with DNAH8-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with glutamic acid at codon 1005 of the DNAH8 protein (p.Gly1005Glu). The glycine residue is weakly conserved and there is a moderate physicochemical difference between glycine and glutamic acid.
