Genes affected

VIPAS39 (HGNC:20347): (VPS33B interacting protein, apical-basolateral polarity regulator, spe-39 homolog) Involved in endosome to lysosome transport and intracellular protein transport. Acts upstream of or within collagen metabolic process and peptidyl-lysine hydroxylation. Located in Golgi apparatus and endosome. Implicated in arthrogryposis, renal dysfunction, and cholestasis 2.
