Mouse Study Finds Link Between Key Mitochondrial Protein and CMT2A, Making It a Possible Therapeutic Target

In a study conducted in mice, scientists led by an MDA-funded researcher found that increasing the amount of a certain mitochondrial membrane protein, mitofusin-1 (MFN1), lessened symptoms of Charcot-Marie-Tooth disease (CMT) type 2A. The findings suggest that it may be possible to treat CMT2A using gene-replacement therapies that deliver functional copies of missing or mutated . . .
