Description

In affected members of an Italian family with Charcot-Marie-Tooth disease-2A2A (CMT2A2A; 609260) originally reported by Muglia et al. (2001), Zuchner et al. (2004) identified a heterozygous 751C-G transversion in the MFN2 gene, resulting in a pro251-to-ala (P251A) substitution. Age at disease onset ranged from 8 to 50 years.
