Description

In affected members of a family with Charcot-Marie-Tooth disease-2A2A (CMT2A2A; 609260) originally reported by Pericak-Vance et al. (1997), Zuchner et al. (2004) identified a heterozygous 227T-C transition in the MFN2 gene, resulting in a leu76-to-pro (L76P) substitution. Age at disease onset ranged from 7 to 44 years.
