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 testingNew York Genome CenterMay 27, 2021The inherited heterozygous c.2038G>A (p.Asp680Asn) missense variant identified in the DNAH11 gene has not been reported in affected individuals in the literature. The variant has 0.0007167 allele frequency in the gnomAD(v3) database (109 out of 152078 heterozygous alleles, no homozygotes) suggesting it is not a common benign variant in the populations represented in that database. In silico tools provide conflicting predictions about potentialpathogenicity of this variant (CADD score = 21.3, REVEL score = 0.066). Based on the available evidence, the inherited heterozygous c.2038G>A(p.Asp680Asn) variant identified in the DNAH11 gene is reported as a variant of uncertain significance. -

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 10, 2018The p.D680N variant (also known as c.2038G>A), located in coding exon 12 of the DNAH11 gene, results from a G to A substitution at nucleotide position 2038. The aspartic acid at codon 680 is replaced by asparagine, an amino acid with highly similar properties. This amino acid position is not well 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 alteration remains unclear. -
