A mutation in the heptad repeat 2 domain of MFN2 in a large CMT2A family

J Peripher Nerv Syst. 2018 Mar;23(1):36-39. doi: 10.1111/jns.12248. Epub 2018 Feb 6.

Abstract

Dominant mutations in MFN2 cause a range of phenotypes, including severe, early-onset axonal neuropathy, "classical CMT2," and late-onset axonal neuropathies. We report a large family with an axonal polyneuropathy, with clinical onset in the 20s, followed by slow progression.

Keywords: CMT; Charcot-Marie-Tooth disease; neuropathy.
