Two new mutations causing Charcot-Marie-Tooth disease type 1 (CMT1) were identified in the gene PMP2, and associated with variable clinical severity, including slow progression of disease and mild symptoms, according to a study. The study, “Peripheral myelin protein 2 – a novel…

Neuropathic pain — that due to damage in the nervous system — affects almost one-third of patients with Charcot-Marie-Tooth type 1 A (CMT1A) and is linked to greater disability and depression, a study from Serbia reports. The study “Neuropathic pain in patients with Charcot-Marie-Tooth type 1A” was published in…

Rare disease-themed videos glowed on a large screen before an audience of people in wheelchairs, with crutches, and bearing oxygen tanks this Nov. 9 and 10 in San Francisco. Disorder: The Rare Disease Film Festival strives to eventually host a film about every one of the nearly 7,000 rare…

Using CRISPR/Cas9 technology to reduce the expression of the gene PMP22 in nerve cells can improve nerve functioning and limit demyelination (damage to the protective covering that surrounds nerve fibers) in a mouse model of Charcot-Marie-Tooth disease 1A (CMT1A), a new proof-of-concept study reports. The study, titled “…

Embelin, a small molecule, rescues hallmark features of Charcot-Marie-Tooth (CMT) disease by stopping a mutant protein from entering the cell’s nucleus, a study in a fly model of the disease showed. Titled “Transcriptional dysregulation by a nucleus-localized aminoacyl-tRNA synthetase associated with Charcot-Marie-Tooth neuropathy,” the study was published…

A novel mutation in the gene PRPS1 was identified in the first case of X-linked Charcot-Marie-Tooth disease type 5 (CMTX5) in China. The finding was described in a case report published in the journal Neuropathology, titled “A novel mutation in PRPS1 gene causes X‐linked Charcot‐Marie‐Tooth disease‐5.”…

Researchers have successfully used adeno-associated virus-mediated gene therapy to treat mice that replicated a novel mutation found in a Charcot-Marie-Tooth Type 2D patient with severe disease. The study describing the scientists’ work, “Allele-specific RNA interference prevents neuropathy in Charcot-Marie-Tooth disease type 2D mouse models,” was published in the…

Mutations in the GDAP1 gene — which are linked to Charcot-Marie-Tooth disease type 2K (CMT2K) — can affect how well mitochondria are able to keep cells supplied with essential energy, a lab study reports. However, the severity of mitochondrial impairment varies according to a mutation’s site within the gene. The study…

The natural course of dominant intermediate Charcot-Marie-Tooth (CMT) disease neuropathy subtype C includes progressively worsening mobility and quality of life over time, a long-term follow-up study shows. Titled “Longitudinal 16‐year study of dominant intermediate CMT type C neuropathy,” the study was published in the journal Muscle…

A new system can detect the worsening of hand function over time in people with Charcot-Marie-Tooth disease (CMT), researchers in Italy have found. Their study, titled “Characteristics and Evolution of the Charcot-Marie-Tooth Hand: an Observational Study,” was published in the European Medical Journal. Symptoms affecting…
