Charcot-Marie-Tooth type 4B is caused by mutations in the gene encoding myotubularin-related protein-2

Nat Genet. 2000 May;25(1):17-9. doi: 10.1038/75542.

Abstract

A gene mutated in Charcot-Marie-Tooth disease type 4B (CMT4B), an autosomal recessive demyelinating neuropathy with myelin outfoldings, has been mapped on chromosome 11q22. Using a positional-cloning strategy, we identified in unrelated CMT4B patients mutations occurring in the gene MTMR2, encoding myotubularin-related protein-2, a dual specificity phosphatase (DSP).
