MTMR2 - myotubularin related protein 2 Gene
Also Known as CMT4B; CMT4B1
Species: Homo sapiens
About MTMR2
This gene has 60 transcripts (splice variants), 231 orthologues, 13 paralogues and is associated with 2 phenotypes. Ubiquitous expression in testis (RPKM 15.9), brain (RPKM 10.1) and 25 other tissues.
Summary
This gene is a member of the myotubularin family of phosphoinositide lipid phosphatases. The encoded protein possesses Phosphatase activity towards phosphatidylinositol-3-phosphate and phosphatidylinositol-3,5-bisphosphate. Mutations in this gene are a cause of Charcot-Marie-Tooth disease type 4B, an autosomal recessive demyelinating neuropathy. Alternatively spliced transcript variants encoding multiple isoforms have been found for this gene. [provided by RefSeq, Aug 2011]
