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]

Identified in a patient in published literature with primary ciliary dyskinesia who harbored another DNAH5 variant on the opposite allele (in trans), but was also reported to harbor another DNAH5 variant on the same allele (in cis) with p.(N402K) as well (Hong T. Lin et al. (2021) J Pediatr Genet. https://www.thieme-connect.com/products/ejournals/abstract/10.1055/s-0041-1733940); Identified in a patient in published literature with primary ciliary dyskinesia who harbored another DNAH5 variant but it is not known whether the variants occurred on the same (in cis) or on different (in trans) chromosomes (PMID: 30300419); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 37575649, Hong2021[Article], 30300419) -

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. -

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Variant classified as Uncertain Significance - Favor Benign. The p.Asn402Lys var iant in DNAH5 was identified in 1 heterozygous individual with primary ciliary d yskinesia (Cozzolino 2009). It has also been identified in 0.23% (153/66670) of European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broa dinstitute.org; dbSNP rs140782270). Computational prediction tools and conservat ion analysis do not provide strong support for or against an impact to the prote in. In summary, while the clinical significance of the p.Asn402Lys variant is un certain, its frequency suggests that it is more likely to be benign. -
