TET3 and autosomal dominant cerebellar ataxia, deafness and narcolepsy: Using the TET3 episignature generated by training the TET3 cohort samples against controls and 38 other episignatures and our supervised classification algorithm, we observed high MVP scores partially overlapping those of TET3-deficient samples for individuals with ADCADN, which results from mutations in the DNA methyltransferase writer DNMT130.
