Genes affected

RABL2B (HGNC:9800): (RAB, member of RAS oncogene family like 2B) The RABL2B protein is a member of the RAB gene family which belongs to the RAS GTPase superfamily. RABL2B is located within a subtelomeric region of 22q13.3. Multiple alternatively spliced transcript variants encoding several different isoforms have been found for this gene.
