GDAP1 mutations differ in their effects on mitochondrial dynamics and apoptosis depending on the mode of inheritance.

Abstract excerpt

Mutations in the GDAP1 gene lead to recessively or dominantly inherited peripheral neuropathies (Charcot-Marie-Tooth disease; CMT). Here, we demonstrate that GDAP1 is a mitochondrial fission factor whose activity is dependent on the fission factors Drp1 and Fis1. Unlike other mitochondrial fission factors, GDAP1 overexpression or knockdown does not influence the susceptibility of cells to apoptotic stimuli....
