Genes affected

DRC3 (HGNC:25384): (dynein regulatory complex subunit 3) Located in axoneme. [provided by Alliance of Genome Resources, Apr 2022]

DRC3 links:

ATPAF2 (HGNC:18802): (ATP synthase mitochondrial F1 complex assembly factor 2) This gene encodes an assembly factor for the F(1) component of the mitochondrial ATP synthase. This protein binds specifically to the F1 alpha subunit and is thought to prevent this subunit from forming nonproductive homooligomers during enzyme assembly. This gene is located within the Smith-Magenis syndrome region on chromosome 17. An alternatively spliced transcript variant has been described, but its biological validity has not been determined. [provided by RefSeq, Jul 2008]
