What is the rs4253778 variant?

rs4253778 is a SNP (single nucleotide polymorphism) in the PPARA (Peroxisome Proliferator Activated Receptor Alpha) gene. It belongs to the Metabolic category and is part of the Mitochondrial Energy Production & PEM biological cluster. PPARA encodes PPAR-alpha, a nuclear receptor that activates fatty acid oxidation genes in the liver and other tissues.

Biological role and pathway

This variant sits within the PPARA gene, which is involved in the fatty acid oxidation / mitochondrial biogenesis pathway. Genes within the Mitochondrial Energy Production & PEM 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.

rs4253778 and Long COVID / ME-CFS research

PPARA-driven fatty acid oxidation is essential for sustained energy production; variants may impair mitochondrial energy metabolism and contribute to fatigue and PEM in Long COVID.
