What is the rs2735611 variant?

rs2735611 is a SNP (single nucleotide polymorphism) in the PER1 (Period Circadian Regulator 1) gene. It belongs to the Circadian category and is part of the Sleep & Circadian Rhythm biological cluster. PER1 encodes a core circadian clock protein that, with PER2 and CRY proteins, represses CLOCK/BMAL1 transcriptional activity.

Biological role and pathway

This variant sits within the PER1 gene, which is involved in the circadian clock machinery pathway. Genes within the Sleep & Circadian Rhythm 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.

rs2735611 and Long COVID / ME-CFS research

PER1 variants may affect the robustness of circadian rhythms and contribute to sleep and immune dysregulation in Long COVID.

Frequently asked questions

What is the rs2735611 variant in the PER1 gene?

rs2735611 is a single nucleotide polymorphism (SNP) located in the PER1 (Period Circadian Regulator 1) gene, which is involved in circadian clock machinery. PER1 encodes a core circadian clock protein that, with PER2 and CRY proteins, represses CLOCK/BMAL1 transcriptional activity.

How may the rs2735611 variant relate to Long COVID or ME/CFS?

PER1 variants may affect the robustness of circadian rhythms and contribute to sleep and immune dysregulation in Long COVID.

Can a consumer DNA test detect the rs2735611 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.
