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]

The p.L2137I variant (also known as c.6409C>A), located in coding exon 38 of the DNAH5 gene, results from a C to A substitution at nucleotide position 6409. The leucine at codon 2137 is replaced by isoleucine, an amino acid with highly similar properties. This variant was previously reported in the SNPDatabase as rs181884470. Based on data from the 1000 Genomes Project, the A allele has an overall frequency of approximately 0.1% (2/2098) total alleles studied. The highest observed frequency was 1.82% (2/110) Puerto Rican alleles. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since clinical data on this variant is limited at this time, its clinical significance is unclear. -
