question: What is known about diseases associated with mutations in the CHCHD10 gene?
answer: Mutation c.197G>T p.G66V in CHCHD10 is the cause of the lower motor neuron syndrome LOSMoN/SMAJ. 
  Mutations in the CHCHD10 gene have been identified in a large family with a complex phenotype variably associating frontotemporal dementia (FTD) with amyotrophic lateral sclerosis (ALS), cerebellar ataxia, myopathy, and hearing impairment.
  Other findings links CHCHD10 mutations to mitochondrial myopathy.
