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.V2184A variant (also known as c.6551T>C), located in coding exon 39 of the DNAH5 gene, results from a T to C substitution at nucleotide position 6551. The valine at codon 2184 is replaced by alanine, an amino acid with similar properties. This variant was previously reported in the SNPDatabase as rs200805455. Based on data from the NHLBI Exome Sequencing Project (ESP), the C allele has an overall frequency of approximately 0.01% (1/13006) total alleles studied and 0.01% (1/8600) European American alleles. This amino acid position is highly 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 variant remains unclear. -

The DNAH5 p.Val2184Ala variant was not identified in the literature nor was it identified in Cosmic or LOVD 3.0. The variant was identified in dbSNP (ID: rs200805455) and ClinVar (classified as a VUS by Invitae). The variant was identified in control databases in 19 of 282754 chromosomes at a frequency of 0.000067 (Genome Aggregation Database March 6, 2019, v2.1.1). The variant was also observed in the European (non-Finnish) population in 19 of 129082 chromosomes (freq: 0.000147), but was not observed in the African, Latino, Ashkenazi Jewish, East Asian, European (Finnish), Other, or South Asian populations. The p.Val2184 residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
