Newly identified mutations in the IGHMBP2 gene have been associated with Charcot-Marie-Tooth disease type 2S (CMT2S), according to a study in China. Data also suggested that missense IGHMBP2 mutations localized in the functional domains of the resulting IGHMBP2 enzyme may be linked to more severe forms of the disease. Missense mutations…

Enrollment into Pharnext’s pivotal Phase 3 PREMIER clinical trial, testing the effectiveness and safety of PXT3003 for people with mild-to-moderate Charcot-Marie-Tooth type 1A (CMT1A), is complete. The study exceeded its target number of participants, recruiting 387 patients in 52 centers across the U.S., Canada, Europe, and Israel. Top-line…

IFB-088, a small molecule that modulates a cell’s response to stress, improved myelin formation in mouse models of Charcot-Marie-Tooth type 1 (CMT1) disease, and this translated into faster nerve signal transmission and better motor function, a study found. If the findings hold true in humans, they could lead to…

In rare cases, de novo or non-inherited mutations in one copy of the POLR3B gene can cause an early-onset demyelinating form of Charcot-Marie-Tooth disease (CMT), according to a study from Japan involving more than 800 CMT patients. While mutations in both POLR3B gene copies have been shown to cause a rare neurodevelopmental…

Pharnext’s PXT3003, a potential treatment for Charcot–Marie–Tooth type 1A (CMT1A), continues to show sustained safety and efficacy in a Phase 3 open-label extension study. Data collected in April show that PXT3003 continues to ease disabilities, based on scores in the overall neuropathy limitations scale (ONLS), a…

Ultrasound may help diagnose and direct treatment for carpal tunnel syndrome in people with Charcot-Marie-Tooth disease type 1 subtype A (CMT1A), a case report suggests. The report, “Nerve Ultrasound Findings before and after Surgery in a Patient with Charcot-Marie-Tooth Disease Type 1A and Comorbid Carpal Tunnel Syndrome,” was…

A new genetic mutation was identified in an Italian woman with severe muscle wasting in the arms and legs due to Charcot-Marie-Tooth disease type 2 (CMT2). The finding is part of a study that described the clinical characteristics of 13 patients carrying disease-causing mutations in MFN2, a gene that…

A Russian military plane crash near Tetiana Zamorska’s home in Kyiv, Ukraine, was a sign that it was time for her and her family to leave. The treacherous, 34-hour pilgrimage that ultimately brought the group of eight by car to temporary accommodations in neighboring Poland last month was physically and emotionally difficult,…

A 12-year-old boy with Charcot-Marie-Tooth type 1 (CMT1) was found in a rare case study to carry variants in two different genes, MPZ and MFN2. The variant in MPZ has been previously described and was deemed likely the main cause of CMT in the patient, while the MFN2 variant…

Treatment with inhibitors of the HDAC6 protein, including the new compound CKD-504, was able to restore proper connections between nerves and muscles and improve movement in zebrafish with low levels of GARS — the gene implicated in Charcot-Marie-Tooth disease type 2D, a study found. The results suggest that HDAC6 blockade may…
