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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2023The c.12343G>A (p.D4115N) alteration is located in exon 62 (coding exon 62) of the DNAH3 gene. This alteration results from a G to A substitution at nucleotide position 12343, causing the aspartic acid (D) at amino acid position 4115 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
