Summaries for RAB27A Gene

Entrez Gene Summary for RAB27A Gene

  • The protein encoded by this gene belongs to the small GTPase superfamily, Rab family. The protein is membrane-bound and may be involved in protein transport and small GTPase mediated signal transduction. Mutations in this gene are associated with Griscelli syndrome type 2. Alternative splicing occurs at this locus and four transcript variants encoding the same protein have been identified. [provided by RefSeq, Jul 2008]

GeneCards Summary for RAB27A Gene

RAB27A (RAB27A, Member RAS Oncogene Family) is a Protein Coding gene. Diseases associated with RAB27A include Griscelli Syndrome, Type 2 and Hemophagocytic Lymphohistiocytosis. Among its related pathways are Immune System and Vesicle-mediated transport. GO annotations related to this gene include GTP binding and protein domain specific binding. An important paralog of this gene is RAB27B.

GS2 patients also develop an uncontrolled T-lymphocyte and macrophage activation syndrome, known as hemophagocytic syndrome, leading to death in the absence of bone marrow transplantation. Neurological impairment is present in some patients, likely as a result of hemophagocytic syndrome. {ECO:0000269 PubMed:10835631}.
