CHCHD10 and Mitochondrial myopathy: Pathogenic variants in the mitochondrial protein coiled-coil-helix-coiled-coil-helix domain-containing protein 10 (CHCHD10) were first associated with autosomal dominant familial amyotrophic lateral sclerosis and frontotemporal dementia (ALS-FTD) (Bannwarth et al, 2014; Johnson et al, 2014; Muller et al, 2014), and later with other diseases, including Charcot Marie Tooth neuropathy (Auranen et al, 2015), spinal muscular atrophy (Penttila et al, 2015), mitochondrial myopathy, and cardiomyopathy (Shammas et al, 2022).
