rs1550117

What is the rs1550117 variant?

rs1550117 is a SNP (single nucleotide polymorphism) in the DNMT3A (DNA Methyltransferase 3 Alpha) gene. It belongs to the Epigenetics category and is part of the Methylation & Neurotransmitters biological cluster. DNMT3A encodes a de novo DNA methyltransferase responsible for establishing DNA methylation patterns during development and in response to environmental signals.

Biological role and pathway

This variant sits within the DNMT3A gene, which is involved in the de novo DNA methylation / epigenetic regulation pathway. Genes within the Methylation & Neurotransmitters cluster work together to maintain balanced function across interconnected biological systems.

Variants in genes within this pathway may influence an individual's predisposition to altered function — particularly under conditions of physiological stress such as viral infection or prolonged illness.
