Relevance to Autism

Rare inherited loss-of-function and damaging missense variants in the DNAH3 gene were identified in ASD probands from the Simons Simplex Collection (Krumm et al., 2015) and in Chinese ASD probands (Guo et al., 2017). Transmission and De Novo Association (TADA) analysis of a cohort of 536 Chinese ASD probands and 1457 Chinese controls in Guo et al., 2017 identified the DNAH3 gene as an ASD candidate gene with a PTADA between 0.001 and 0.005 (0.00758); however, PTADA for this gene failed to reach significance (P < 0.01) following TADA analysis using a combined cohort of Chinese ASD probands and controls, as well as ASD probands and controls from the Simons Simplex Collection and the Autism Sequencing Consortium.

Molecular Function

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.
