Genes affected

DNAH3 (HGNC:2949): (dynein axonemal heavy chain 3) 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. Alternative splicing results in multiple transcript variants encoding distinct isoforms.

The c.11671C>T (p.R3891W) alteration is located in exon 60 (coding exon 60) of the DNAH3 gene. This alteration results from a C to T substitution at nucleotide position 11671, causing the arginine (R) at amino acid position 3891 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
