A specific mutation in a small RNA molecule called miR-149 was found to be linked to both age of onset and severity in patients with Charcot-Marie-Tooth disease type 1A (CMT1A), according to researchers. Their study, “Association of miR-149 polymorphism with onset age and severity in Charcot-Marie-Tooth disease…

Specific genetic sequences are critical for normal expression of Pmp22, the critical gene in Charcot-Marie-Tooth disease type 1A (CMT1A), a new study shows. The study, “Regulation of the neuropathy-associated Pmp22 gene by a distal super-enhancer,” was published in the journal Human Molecular Genetics. CMT1A is caused by…

The National Organization for Rare Disorders (NORD) will celebrate the 35th anniversary of both the 1983 Orphan Drug Act and NORD’s founding at a dinner tonight in Washington, D.C. The 2018 Rare Impact Awards, to be held at the Andrew W. Mellon Auditorium, will be webcast via Facebook for those…

Inhibition of a tumor suppressor enzyme called MST1 could reverse the effects of the genetic mutations that cause Charcot-Marie-Tooth disease type 4J (CMT4J), researchers show in a fruit fly study. The study, “Loss-of-function mutation in Hippo suppressed enlargement of lysosomes and neurodegeneration caused by dFIG4 knockdown,”…

Researchers in France have found that a new technique to assess muscle electrical activity, called Motor Unit Number Index (MUNIX), correlates with clinical disability in Charcot-Marie-Tooth disease type 1 (CMT1) and can be used to monitor disease progression. The study, “Motor unit number index correlates with disability in Charcot-Marie-Tooth disease,”…

Researchers at University of Michigan developed a new method that can help identify potential targets relevant for normal peripheral nerve activity and Charcot-Marie-Tooth (CMT) disease therapy development. Based on genetic analysis of non-coding regions in genes coupled with experimental cell line testing, the new method revealed the Tubb2b gene as an…

Individuals with Charcot-Marie-Tooth disease type 2 (CMT2) have lower muscle strength compared to those who don’t have CMT2. This loss of muscle strengths leads to decreased balance and inability to perform normal tasks. A study with those findings, “Evaluation of muscle strength, balance and functionality of individuals with…
