What is the rs3735976 variant?
rs3735976 is a SNP (single nucleotide polymorphism) in the TAGLN (Transgelin (SM22-Alpha)) gene. It belongs to the Connective Tissue category and is part of the Coagulation & Microcirculation biological cluster. TAGLN encodes SM22-alpha/transgelin, an actin-binding protein expressed in smooth muscle and myofibroblasts.
Biological role and pathway
This variant sits within the TAGLN gene, which is involved in the smooth muscle / myofibroblast differentiation pathway. Genes within the Coagulation & Microcirculation 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.
rs3735976 and Long COVID / ME-CFS research
TAGLN expression marks myofibroblast differentiation in fibrotic tissue; elevated TAGLN in COVID-19 lung may reflect fibroblast activation contributing to Long COVID pulmonary fibrosis.

Frequently asked questions
What is the rs3735976 variant in the TAGLN gene?
rs3735976 is a single nucleotide polymorphism (SNP) located in the TAGLN (Transgelin (SM22-Alpha)) gene, which is involved in smooth muscle / myofibroblast differentiation. TAGLN encodes SM22-alpha/transgelin, an actin-binding protein expressed in smooth muscle and myofibroblasts.
How may the rs3735976 variant relate to Long COVID or ME/CFS?
TAGLN expression marks myofibroblast differentiation in fibrotic tissue; elevated TAGLN in COVID-19 lung may reflect fibroblast activation contributing to Long COVID pulmonary fibrosis.
Can a consumer DNA test detect the rs3735976 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.
