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]
DNAAF3-AS1 (HGNC:55292): (DNAAF3 antisense RNA 1)

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.50G>A (p.G17D) alteration is located in exon 1 (coding exon 1) of the DNAAF3 gene. This alteration results from a G to A substitution at nucleotide position 50, causing the glycine (G) at amino acid position 17 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

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). -
