rs2235756

What is the rs2235756 variant?

rs2235756 is a SNP (single nucleotide polymorphism) in the PCK1 (Phosphoenolpyruvate Carboxykinase 1) gene. It belongs to the Metabolic category and is part of the Metabolic Regulation biological cluster. PCK1 encodes cytosolic PEPCK, the rate-controlling enzyme of gluconeogenesis, which converts oxaloacetate to phosphoenolpyruvate.

Biological role and pathway

This variant sits within the PCK1 gene, which is involved in the gluconeogenesis pathway. Genes within the Metabolic Regulation 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.
