Genes affected
DNAH11 (HGNC:2942): (dynein axonemal heavy chain 11) This gene encodes a ciliary outer dynein arm protein and is a member of the dynein heavy chain family. It is a microtubule-dependent motor ATPase and has been reported to be involved in the movement of respiratory cilia. Mutations in this gene have been implicated in causing Kartagener Syndrome (a combination of situs inversus totalis and Primary Ciliary Dyskinesia (PCD), also called Immotile Cilia Syndrome 1 (ICS1)) and male sterility.

Uncertain significance, criteria provided, single submitterclinical testingGeneDxMay 30, 2018The 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. -
