MSTO1 and Ataxia: Notably, a family with an autosomal‐dominant mutation in MSTO1 was recently identified (Gal et al., 2016), with the affected subjects presenting symptoms partly overlapping those of our patients, for example, myopathy, ataxia, skeletal alterations, in addition to psychotic features, for example, schizophrenia or autism, which are not present in our cases.
