Yeast Model May Help Assess CMT4A Mutations

A yeast model could be used to assess the biological consequences of mutations in the GDAP1  gene, which can cause Charcot-Marie-Tooth type 4A (CMT4A). The model was described in “Pathogenic Effect of GDAP1 Gene Mutations in a Yeast Model,” a study published in the journal Genes.

Some Patients with CMTX Show Cognitive Deficits, Study Suggests

Some patients with Charcot-Marie-Tooth Disease type X (CMTX) exhibit cognitive deficits, such as difficulties with executive function and reading, a recent study shows. The study, “Evidence for Cognitive Deficits in X-Linked Charcot-Marie-Tooth Disease,” was published in the Journal of the International Neuropsychological Society. CMTX, also…

Case Report Describes White Matter Lesions, New Mutations In CMTX

Central nervous system (CNS) dysfunction, manifesting as reversible posterior leukoencephalopathy , was observed in three people with X-linked Charcot-Marie-Tooth (CMTX) and described in a recent case report. The case report, “Recurrent episodes of reversible posterior leukoencephalopathy in three Chinese families with GJB1 mutations in…

Case Report Describes First Case of CMTX5 in a Chinese Person

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.”…

September Is Charcot-Marie-Tooth Awareness Month

September is Charcot-Marie-Tooth (CMT) awareness month, and the Hereditary Neuropathy Foundation (HNF) suggests it is an ideal time to increase awareness — among the general public, educators, legislators, and  physicians — about accurately diagnosing CMT and other inherited neuropathies (nerve diseases). In a press release announcing the month-long observation, the nonprofit…
