Charcot-Marie-Tooth study to get $250K grant


The Muscular Dystrophy Association (MDA) and Charcot-Marie-Tooth Research Foundation (CMTRF) have announced joint funding for a study by Alessandra Bolino at San Raffaele Hospital (Ospedale San Raffaele), Italy, on restoring membrane trafficking in Charcot-Marie-Tooth (CMT) neuropathies with aberrant myelin. This will be a three-year study, with the grant totaling $263,450.

“We at the Muscular Dystrophy Association welcome this opportunity to join with CMTRF to support this important research,” says Sharon Hesterlee, chief research officer at the MDA. 

“Collaborating with like-minded organizations to fund research that may lead to increasing advancements in treatments and cures for Charcot-Marie-Tooth disease will increase our efficiency and help accelerate MDA’s overall mission to improve the lives of neuromuscular disease patients.” 

CMT neuropathies are generally characterized by progressive muscular atrophy and weakness, with an age at onset usually between the first and the second decade of life. 

Among CMT neuropathies, CMT4B1 is a very severe demyelinating neuropathy with childhood onset, characterized by myelin outfoldings, redundant loops of myelin in the nerve that degenerate causing axonal problems. This form of aberrant myelin is also a pathological feature of other forms of demyelinating CMT, such as CMT4B2, B3, CMT4C and CMT4H. 

Study details

The laboratory previously demonstrated that loss of MTMR2 (myotubularin-related 2) phosphatase is the cause of the disease. By investigating why loss of MTMR2 in Schwann cells provokes aberrant myelin, they identified a novel mechanism by which MTMR2 and its lipid substrate coordinate cytoskeleton dynamics and membrane growth within myelin-forming cells. In this project, researchers will further explore this mechanism of relevance in cell biology and test whether pharmacological and/or genetic modulation of these pathways can represent an effective strategy for the therapy of CMT4B with aberrant myelin.

“The CMT Research Foundation is pleased to partner with the Muscular Dystrophy Association on Dr. Bolino’s CMT4B1 project,” said Cleary Simpson CEO of the CMTRF.

“CMTRF is ready to form alliances with organizations that can get us closer to treatments or a cure for CMT.”
