What is the rs1065369 variant?

rs1065369 is a SNP (single nucleotide polymorphism) in the KYNU (Kynureninase) gene. It belongs to the Metabolic category and is part of the Methylation & Neurotransmitters biological cluster. KYNU encodes kynureninase, which converts kynurenine to anthranilic acid or 3-hydroxykynurenine, a precursor to NAD+ via the de novo pathway.

Biological role and pathway

This variant sits within the KYNU gene, which is involved in the kynurenine pathway / NAD+ synthesis 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.

rs1065369 and Long COVID / ME-CFS research

KYNU in the kynurenine pathway metabolizes tryptophan toward NAD+ or neurotoxic quinolinic acid; dysregulation may contribute to NAD+ depletion and neurological symptoms in Long COVID.

Frequently asked questions

What is the rs1065369 variant in the KYNU gene?

rs1065369 is a single nucleotide polymorphism (SNP) located in the KYNU (Kynureninase) gene, which is involved in kynurenine pathway / NAD+ synthesis. KYNU encodes kynureninase, which converts kynurenine to anthranilic acid or 3-hydroxykynurenine, a precursor to NAD+ via the de novo pathway.

How may the rs1065369 variant relate to Long COVID or ME/CFS?

KYNU in the kynurenine pathway metabolizes tryptophan toward NAD+ or neurotoxic quinolinic acid; dysregulation may contribute to NAD+ depletion and neurological symptoms in Long COVID.

Can a consumer DNA test detect the rs1065369 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.
