Dnmt1
This gene encodes an enzyme that transfers methyl groups to cytosine nucleotides of genomic DNA. This protein is the major enzyme responsible for maintaining methylation patterns following DNA replication and shows a preference for hemi-methylated DNA. Methylation of DNA is an important component of mammalian epigenetic gene regulation. Aberrant methylation patterns are found in human tumors and associated with developmental abnormalities. Variation in this gene has been associated with cerebellar ataxia, deafness, and narcolepsy, and neuropathy, hereditary sensory, type IE. Alternative splicing results in multiple transcript variants.

Forensic Context
A study in mice demonstrated that following clodronate liposome pre-treatment and controlled cortical impact injury, a compensatory emergency monopoiesis generated transcriptionally distinct Ly6Chi monocyte subsets, including a pro-resolving immunoregulatory population enriched for Apoe and Chil3 and a unique neutrophil-like monocyte cluster defined by granule genes Elane, Prtn3, MPO, and Ctsg [Erwin K. Gudenschwager Basso et al. DOI:10.1186/s12974-024-03032-8]. A study in porcine skin demonstrated that the DNMT1 was significantly decreased at 7 days postexposure following both sulfur mustard and thermal burn injuries [Price et al. DOI:10.080/15569520903097754].
