Genes affected

DNAI4 (HGNC:26252): (dynein axonemal intermediate chain 4) Predicted to enable dynein heavy chain binding activity and dynein light chain binding activity. Predicted to be involved in axonemal dynein complex assembly and cilium movement. Predicted to act upstream of or within hematopoietic progenitor cell differentiation. Predicted to be located in axoneme; dynein axonemal particle; and motile cilium. Predicted to be part of axonemal dynein complex. [provided by Alliance of Genome Resources, Apr 2022]
