What is the rs35724 variant?

rs35724 is a SNP (single nucleotide polymorphism) in the NR1H4 (Nuclear Receptor Subfamily 1 Group H Member 4 (FXR)) gene. It belongs to the Metabolic category and is part of the Metabolic Regulation biological cluster. NR1H4 encodes FXR (farnesoid X receptor), a nuclear receptor for bile acids that regulates bile acid synthesis, lipid metabolism, and gut barrier function.

Biological role and pathway

This variant sits within the NR1H4 gene, which is involved in the bile acid sensing / gut homeostasis 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.

rs35724 and Long COVID / ME-CFS research

FXR regulates gut bile acid homeostasis and intestinal barrier integrity; FXR variants may affect gut-liver axis function and contribute to GI symptoms in Long COVID.

Frequently asked questions

What is the rs35724 variant in the NR1H4 gene?

rs35724 is a single nucleotide polymorphism (SNP) located in the NR1H4 (Nuclear Receptor Subfamily 1 Group H Member 4 (FXR)) gene, which is involved in bile acid sensing / gut homeostasis. NR1H4 encodes FXR (farnesoid X receptor), a nuclear receptor for bile acids that regulates bile acid synthesis, lipid metabolism, and gut barrier function.

How may the rs35724 variant relate to Long COVID or ME/CFS?

FXR regulates gut bile acid homeostasis and intestinal barrier integrity; FXR variants may affect gut-liver axis function and contribute to GI symptoms in Long COVID.

Can a consumer DNA test detect the rs35724 variant?

Many consumer DNA tests such as 23andMe, AncestryDNA, and MyHeritage genotype common SNPs. ChronicDNA analyses your raw DNA file and reports on variants studied in relation to chronic illness, immune function, and metabolism. This is not a diagnostic service — results are informational and educational only.
