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. [provided by RefSeq, Mar 2013]
CDCA7L (HGNC:30777): (cell division cycle associated 7 like) Acts upstream of or within positive regulation of cell population proliferation. Located in cytosol; fibrillar center; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

The p.R4449H variant (also known as c.13346G>A), located in coding exon 82 of the DNAH11 gene, results from a G to A substitution at nucleotide position 13346. The arginine at codon 4449 is replaced by histidine, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species, and histidine is the reference amino acid in other 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. -
