What is the rs17293632 variant?
rs17293632 is a SNP (single nucleotide polymorphism) in the SMAD3 (SMAD Family Member 3) gene. It belongs to the Signaling category and is part of the Cellular Signaling biological cluster. SMAD3 mediates both TGF-beta and activin signaling and is involved in immune regulation, fibrosis, and T regulatory cell function.
Biological role and pathway
This variant sits within the SMAD3 gene, which is involved in the TGF-beta/activin signaling pathway. Genes within the Cellular Signaling 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.
rs17293632 and Long COVID / ME-CFS research
SMAD3 variants affecting TGF-beta signaling may influence the balance between immune tolerance and fibrotic repair in Long COVID.
