Genes affected

RAB38 (HGNC:9776): (RAB38, member RAS oncogene family) Enables several functions, including AP-1 adaptor complex binding activity; AP-3 adaptor complex binding activity; and BLOC-2 complex binding activity. Involved in several processes, including endosome to melanosome transport; melanosome assembly; and phagosome acidification. Located in several cellular components, including cytoplasmic vesicle; lysosome; and mitochondria-associated endoplasmic reticulum membrane. [provided by Alliance of Genome Resources, Apr 2022]
