Genes affected

DNAH5 (HGNC:2950): (dynein axonemal heavy chain 5) This gene encodes a dynein protein, which is part of a microtubule-associated motor protein complex consisting of heavy, light, and intermediate chains. This protein is an axonemal heavy chain dynein. It functions as a force-generating protein with ATPase activity, whereby the release of ADP is thought to produce the force-producing power stroke. Mutations in this gene cause primary ciliary dyskinesia type 3, as well as Kartagener syndrome, which are both diseases due to ciliary defects. [provided by RefSeq, Oct 2009]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.K2244M variant (also known as c.6731A>T), located in coding exon 41 of the DNAH5 gene, results from an A to T substitution at nucleotide position 6731. The lysine at codon 2244 is replaced by methionine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.Lys2244Met variant in DNAH5 has not been previously reported in individual s with pulmonary diseases, but has been identified in 3/8600 European American c hromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/E VS/; dbSNP rs187023993). Computational prediction tools and conservation analysi s suggest that this variant may impact the protein, though this information is n ot predictive enough to determine pathogenicity. In summary, the clinical signif icance of the p.Lys2244Met variant is uncertain. -
