Genes affected

DNAAF3 (HGNC:30492): (dynein axonemal assembly factor 3) The protein encoded by this gene is required for the assembly of axonemal inner and outer dynein arms and plays a role in assembling dynein complexes for transport into cilia. Defects in this gene are a cause of primary ciliary dyskinesia type 2 (CILD2). Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2012]

Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Jul 05, 2022	In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 330221). This variant has not been reported in the literature in individuals affected with DNAAF3-related conditions. This variant is present in population databases (rs201101258, gnomAD 0.03%). This sequence change replaces glycine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 17 of the DNAAF3 protein (p.Gly17Asp). -
Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Aug 22, 2022	The p.G17D variant (also known as c.50G>A), located in coding exon 1 of the DNAAF3 gene, results from a G to A substitution at nucleotide position 50. The glycine at codon 17 is replaced by aspartic acid, an amino acid with similar properties. This amino acid position is conserved. 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. -
