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.

The p.K2442R variant (also known as c.7325A>G), located in coding exon 45 of the DNAH11 gene, results from an A to G substitution at nucleotide position 7325. The lysine at codon 2442 is replaced by arginine, an amino acid with highly similar properties. This variant was previously reported in the SNPDatabase as rs114286628. Based on data from the 1000 Genomes Project, the G allele has an overall frequency of approximately 0.14% (3/2098) total alleles studied. The highest observed frequency was 1.14% (2/176) Yoruba alleles. Based on data from the NHLBI Exome Sequencing Project (ESP), the G allele has an overall frequency of approximately 0.05% (6/11828) total alleles studied, having been observed in 0.16% (6/3654) African American alleles. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by SIFT. Since supporting evidence is limited at this time, the clinical significance of this variant remains unclear.
