Genes affected

RAB31 (HGNC:9771): (RAB31, member RAS oncogene family) Enables GDP binding activity and GTP binding activity. Involved in several processes, including Golgi to plasma membrane protein transport; cellular response to insulin stimulus; and receptor internalization. Located in early endosome; phagocytic vesicle; and trans-Golgi network membrane. Biomarker of severe acute respiratory syndrome. [provided by Alliance of Genome Resources, Apr 2022]
