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]

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. -

The DNAH5 c.1198G>A; p.Val400Met variant (rs144575803) is reported in the literature in two siblings affected with tetralogy of Fallot (Izarzugaza 2020). This variant is reported in ClinVar (Variation ID: 219733) and is found in the general population with an overall allele frequency of 0.08% (226/282,092 alleles, including one homozygote) in the Genome Aggregation Database (v2.1.1). This is a missense variant in a highly conserved nucleotide at the first base of exon 10, and computational analyses (Alamut Visual Plus v.1.5.1) predict that this variant may impact splicing by weakening the canonical acceptor splice site. However, further study is needed to determine the functional impact. While the high population frequency suggests that this is likely a benign variant, given the limited clinical data and lack of functional data, the significance of this variant is uncertain at this time.

Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This alteration is classified as likely 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. -
