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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 13, 2024The c.12199T>G (p.C4067G) alteration is located in exon 62 (coding exon 62) of the DNAH3 gene. This alteration results from a T to G substitution at nucleotide position 12199, causing the cysteine (C) at amino acid position 4067 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
