rs2837791

Variant in the MAS1 gene (MAS Proto-Oncogene G Protein-Coupled Receptor)

rs2837791 is a single nucleotide polymorphism (SNP) in the MAS1 gene, involved in ACE2-Ang(1-7)-MAS protective axis. Variants at this position have been studied in relation to immune function, metabolism, and chronic illness.

What is the rs2837791 variant?

rs2837791 is a SNP (single nucleotide polymorphism) in the MAS1 (MAS Proto-Oncogene G Protein-Coupled Receptor) gene. It belongs to the Cardiovascular category and is part of the Autonomic Nervous System biological cluster. MAS1 encodes the GPCR for angiotensin-(1-7), the ACE2 product that activates the protective arm of the renin-angiotensin system.

Biological role and pathway

This variant sits within the MAS1 gene, which is involved in the ACE2-Ang(1-7)-MAS protective axis pathway. Genes within the Autonomic Nervous System 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.

rs2837791 and Long COVID / ME-CFS research

The ACE2/Ang(1-7)/MAS axis is cardioprotective and anti-inflammatory; SARS-CoV-2 binding to ACE2 disrupts this axis, and MAS1 variants may affect recovery of cardiovascular function in Long COVID.

Frequently asked questions

What is the rs2837791 variant in the MAS1 gene?

rs2837791 is a single nucleotide polymorphism (SNP) located in the MAS1 (MAS Proto-Oncogene G Protein-Coupled Receptor) gene, which is involved in ACE2-Ang(1-7)-MAS protective axis. MAS1 encodes the GPCR for angiotensin-(1-7), the ACE2 product that activates the protective arm of the renin-angiotensin system.

How may the rs2837791 variant relate to Long COVID or ME/CFS?

The ACE2/Ang(1-7)/MAS axis is cardioprotective and anti-inflammatory; SARS-CoV-2 binding to ACE2 disrupts this axis, and MAS1 variants may affect recovery of cardiovascular function in Long COVID.

Can a consumer DNA test detect the rs2837791 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.
