This gene is a proto-oncogene whose promoter is methylated by DNA methyltransferase 3B (DNMT3B), which represses the proto-oncogene. However, a catalytically inactive isoform of DNMT3B is overexpressed in lymphomas, leading to hypomethylation of the proto-oncogene's promoter and derepression of the proto-oncogene.

Forensic Context
A study in humans identified the C1orf56 as an important gene in a lasso regression model for age prediction from bloodstain RNA-Seq data, where it had a positive coefficient in the RNAgE dataset [Dørum et al. DOI:10.1016/j.fsigen.2023.102976]. This research, which analyzed mRNA from dried blood stains and whole blood, generated a lasso-selected gene list that achieved a mean absolute error of 4.46 years for age prediction, demonstrating the potential of such markers for forensic age estimation.
