rs41301825

What is the rs41301825 variant?

rs41301825 is a SNP (single nucleotide polymorphism) in the AHCY (Adenosylhomocysteinase) gene. It belongs to the Methylation category and is part of the Methylation & Neurotransmitters biological cluster. AHCY encodes S-adenosylhomocysteine hydrolase, which converts SAH to homocysteine, regulating methylation reactions.

Biological role and pathway

This variant sits within the AHCY gene, which is involved in the one-carbon metabolism 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.
