rs3757441

What is the rs3757441 variant?

rs3757441 is a SNP (single nucleotide polymorphism) in the EZH2 (Enhancer Of Zeste 2 Polycomb Repressive Complex 2 Subunit) gene. It belongs to the Epigenetics category and is part of the Methylation & Neurotransmitters biological cluster. EZH2 is the catalytic subunit of PRC2 that trimethylates H3K27 for Polycomb-mediated gene silencing.

Biological role and pathway

This variant sits within the EZH2 gene, which is involved in the histone H3K27 methylation / gene silencing 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.
