What is the rs11150303 variant?

rs11150303 is a SNP (single nucleotide polymorphism) in the MUC2 (Mucin 2) gene. It belongs to the Gut Microbiome category and is part of the Gut & Microbiome Interaction biological cluster. MUC2 encodes the major secreted gel-forming mucin in the intestine, forming the protective mucus layer separating bacteria from epithelium.

Biological role and pathway

This variant sits within the MUC2 gene, which is involved in the intestinal mucus barrier pathway. Genes within the Gut & Microbiome Interaction 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.

rs11150303 and Long COVID / ME-CFS research

MUC2 barrier function protects against microbial translocation; variants may contribute to gut dysbiosis and systemic inflammation in Long COVID.
