Abstract: Mutations in GDAP1, an outer mitochondrial membrane protein responsible for recessive Charcot-Marie-Tooth disease (CMT4A), have also been associated with CMT2K, a dominant form of the disease. The three CMT2K patients we studied carried a novel dominant GDAP1 mutation, C240Y (c.719Gβ>βA). Mitochondrial respiratory chain complex I activity in fibroblasts from CMT2K patients was 40% lower than in controls, whereas the tubular mitochondria were 33% larger in diameter and the mitochondrial mass was 20% greater. Thus, besides the regulatory role GDAP1 plays in mitochondrial network dynamics, it may also be involved in energy production and in the control of mitochondrial volume. β’ Keywords: GDAP1, Autosomal dominant Charcot-Marie-Tooth disease, CMT2K, Mitochondrial dynamics, Complex I
