The phosphoinositide-3-phosphatase MTMR2 associates with MTMR13, a membrane-associated pseudophosphatase also mutated in type 4B Charcot-Marie-Tooth disease.
Charcot-Marie-Tooth disease type 4B (CMT4B) is a severe, demyelinating peripheral neuropathy characterized by distinctive, focally folded myelin sheaths. CMT4B is caused by recessively inherited mutations in either myotubularin-related 2 (MTMR2) or MTMR13 (also called SET-binding factor 2). MTMR2 encodes a member of the myotubularin family of phosphoinositide-3-phosphatases, which dephosphoryla...

متن کاملDNA duplication associated with Charcot-Marie-Tooth disease type 1A.
Charcot-Marie-tooth disease type 1A (CMT1A) was localized by genetic mapping to a 3 cM interval on human chromosome 17p. DNA markers within this interval revealed a duplication that is completely linked and associated with CMT1A. The duplication was demonstrated in affected individuals by the presence of three alleles at a highly polymorphic locus, by dosage differences at RFLP alleles, and by ...
متن کاملThe CMT4B disease-causing phosphatases Mtmr2 and Mtmr13 localize to the Schwann cell cytoplasm and endomembrane compartments, where they depend upon each other to achieve wild-type levels of protein expression.
The demyelinating peripheral neuropathy Charcot-Marie-Tooth type 4B (CMT4B) is characterized by axonal degeneration and myelin outfoldings. CMT4B results from mutations in either myotubularin-related protein 2 (MTMR2; CMT4B1) or MTMR13 (CMT4B2), phosphoinositide (PI) 3-phosphatases that dephosphorylate phosphatidylinositol 3-phosphate (PtdIns3P) and PtdIns(3,5)P2, lipids which regulate endo-lys...
متن کاملCharcot-Marie-Tooth disease
Charcot-Marie-Tooth (CMT) disease is the most prevalent peripheral inherited neuropathy (1/2500 to 10 000; 2.8/10 000 in Spain), and the mean age at onset is 16 years (range 2 to 50 years, but presentation in the early infancy and as late as the 80's has been reported). Patients present with motor and sensory polyneuropathic semiology (distal lower limb weakness and atrophy, gait abnormalities ...
