Eleanor Williams (Genomics England Curator)

Additional functional evidence: PMID: 31984424 - Maresca et al - studied the effects of different DNMT1 mutations in fibroblasts from four Autosomal Dominant Cerebellar Ataxia-Deafness and Narcolepsy (ADCA-DN) and two Hereditary Sensory Neuropathy with Dementia and Hearing loss (HSN-IE) patients who were unrelated. They found mitochondrial hyper-function that resulted in increased oxidative stress but no change in mitochondrial DNA CpG methylation. They demonstrated that DNMT1 is not localized within mitochondria, but it is associated to the mitochondrial outer membrane. AMPK and mTORC1, the two major sensors of cellular energy, were implicated in the pathogenic mechanism of the most severe DNMT1 mutations.
