Variants in CAMTA1 have been associated with cerebellar ataxia with variable cognitive and behavioral abnormalities (CECBA) [123–125] as well as reduced survival in ALS patients [126, 127]; however, in our cohort we do not observe a correlation between CAMTA1 methylation and age at onset, age at death or survival (data not shown). The gene discussed is CAMTA1; the disease is cerebellar ataxia.
