A form of gene therapy that reduces levels of the PMP22 protein prevented the development of Charcot-Marie-Tooth disease 1A (CMT1A) features in a rat model, a study has found.  The study, “AAV2/9-mediated silencing of PMP22 prevents…

Three people from two unrelated families were found to have Charcot-Marie-Tooth disease type 2Z (CMT2Z) caused by the same MORC2 mutation, called p.Ala406Val, which was linked to severe neuropathy, a case study reported.  One patient’s condition also worsened following treatment with vinblastine…

Scientists have pinpointed a new genetic mutation in the PMP22 gene as the cause of Charcot-Marie-Tooth disease type 3 (CMT3) in a 26-year-old Chinese man. Titled “A novel PMP22 insertion mutation causing Charcot–Marie–Tooth disease type 3,” the case report was published in the journal Medicine. The…

A single dose of a gene therapy delivering a working copy of GJB1 — the gene mutated in X-linked Charcot-Marie-Tooth type 1 disease (CMTX1) — to myelin-producing cells prevented or even reversed myelin loss and motor function impairment in a mouse model of CMTX1. Notably, these benefits were observed…

Children and teenagers with Charcot-Marie-Tooth (CMT) disease have until May 15 to sign up for this year’s edition of Camp Footprint, which will be held virtually from Aug. 2 to 6. …

High-dose PXT3003, an investigational therapy for Charcot-Marie-Tooth disease type 1A (CMT1A), continues to show long-term safety and efficacy, according to an early analysis of a Phase 3 extension study. All participants showed improvements on the Overall Neuropathy Limitation Scale (ONLS), a measure of physical disability. “These new results…

Corrective foot surgery lessened pain and improved foot alignment and quality of life in patients with Charcot-Marie-Tooth (CMT) disease, according to data collected over four years. The findings were published in an article, “A prospective study on surgical management of foot deformities in charcot marie tooth…

Researchers at the University of Michigan and Vanderbilt University have found that mutant PMP22 proteins pair to form a unique, stabilized complex called a dimer. The discovery, which was made using an advanced protein analysis technique, provides new insight into PMP22’s role in…

More than half of the people with rare diseases and their caregivers, asked in a survey, were undecided or less than willing to be vaccinated for COVID-19 if a vaccine was approved under emergency use authorization instead of the routine process, the EveryLife Foundation for Rare Disease reports. These findings…

Until April 30, the CMT Research Foundation (CMTRF) invites people to raise money supporting research into therapies for Charcot-Marie-Tooth disease (CMT), which the foundation will match up to $10,000. Volunteer ambassadors with the foundation created the Spring CMT Research Challenge to accelerate therapy development funding for this…
