Genes affected

DNAH6 (HGNC:2951): (dynein axonemal heavy chain 6) This gene belongs to the dynein family, whose members encode large proteins that are constituents of the microtubule-associated motor protein complex. This complex is composed of dynein heavy, intermediate and light chains, which can be axonemal or cytoplasmic. This protein is an axonemal dynein heavy chain. It is involved in producing force for ciliary beating by using energy from ATP hydrolysis. Mutations in this gene may cause primary ciliary dyskinesia (PCD) as well as heterotaxy.

Jan 17, 2024

The c.284G>A (p.R95Q) alteration is located in exon 3 (coding exon 2) of the DNAH6 gene. This alteration results from a G to A substitution at nucleotide position 284, causing the arginine (R) at amino acid position 95 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
