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]

Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Apr 27, 2016	The R1654Q variant in the DNAH5 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The R1654Q variant was not observed at any significant frequency in approximately 6500 individuals of European and African American ancestry in an external variant database, indicating it is not a common benign variant in these populations. The R1654Q variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is not conserved across species. In silico analysis predicts this variant is probably damaging to the protein structure/function. We interpret R1654Q as a variant of uncertain significance. -

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Apr 03, 2017	The p.R1654Q variant (also known as c.4961G>A), located in coding exon 31 of the DNAH5 gene, results from a G to A substitution at nucleotide position 4961. The arginine at codon 1654 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Uncertain significance, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Jan 12, 2018	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -
