Charcot-Marie-Tooth disease due to a de novo mutation of the RAB7 gene.
We report a 32-year-old patient with Charcot-Marie-Tooth (CMT2B) including foot ulcerations. Genetic analysis identified a de novo mutation in the small GTP-ase late endosomal RAB7 gene, consisting of a c.471G>C, p.Lys157Asn missense mutation. This observation strongly supports the hypothesis that RAB7 mutations are responsible for CMT2B.
