Variant summary: DNAH11 c.8870C>G (p.Ala2957Gly) results in a non-conservative amino acid change in the encoded protein sequence. Two of three in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 6.4e-05 in 234050 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in DNAH11 causing Primary Ciliary Dyskinesia 7, allowing no conclusion about variant significance. c.8870C>G has been reported in the literature in individuals affected with Primary Ciliary Dyskinesia 7 (Chioccioli_2019). These data do not allow any conclusion about variant significance. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 31116566). ClinVar contains an entry for this variant (Variation ID: 454716). Based on the evidence outlined above, the variant was classified as uncertain significance. -
Primary ciliary dyskinesia 7 Uncertain:1

The A2957G variant in the DNAH11 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The A2957G variant is observed in 7/22694 (0.01%) alleles from individuals of African background, in large population cohorts (Lek et al., 2016). The A2957G variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. In-silico analyses, including protein predictors and evolutionary conservation, support that this variant does not alter protein structure/function. We interpret A2957G as a variant of uncertain significance. -
