Genes affected
RAB39B (HGNC:16499): (RAB39B, member RAS oncogene family) This gene encodes a member of the Rab family of proteins. Rab proteins are small GTPases that are involved in vesicular trafficking. Mutations in this gene are associated with X-linked cognitive disability. [provided by RefSeq, Aug 2013]
