What is the rs7118 variant?
rs7118 is a SNP (single nucleotide polymorphism) in the SYK (Spleen Associated Tyrosine Kinase) gene. It belongs to the Adaptive Immunity category and is part of the Adaptive Immunity biological cluster. Syk is a tyrosine kinase that transduces signals from B cell receptors, Fc receptors, integrin signaling, and C-type lectin receptors. It is a convergence point for multiple immune activation pathways.
Biological role and pathway
This variant sits within the SYK gene, which is involved in the immune receptor signaling pathway. Genes within the Adaptive Immunity 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.
rs7118 and Long COVID / ME-CFS research
Syk mediates platelet activation through CLEC2 and FcγRIIA, relevant to Long COVID coagulopathy. Its role in both B cell activation and platelet function makes SYK variants potentially important for multiple Long COVID pathological mechanisms.

Genetic insights from DNA data
Consumer DNA files from 23andMe, AncestryDNA, and MyHeritage contain raw SNP data. When you upload your file to ChronicDNA, the analysis engine checks your genotype against a curated panel of 80+ genes selected for their relevance to Long COVID, ME/CFS, and connected biological pathways - some of which may include SYK and the rs7118 variant.
The report is educational - it explains which variants you carry, what the research says about them, and how they fit into the biological pathways most relevant to chronic illness. Results are presented in plain English with appropriate scientific context, no medical jargon, no scare tactics. All results should be discussed with a qualified healthcare provider.

The following variants in SYK are also studied in relation to chronic illness and may be analysed together for a more complete picture.
Frequently asked questions
What is the rs7118 variant in the SYK gene?
rs7118 is a single nucleotide polymorphism (SNP) located in the SYK (Spleen Associated Tyrosine Kinase) gene, which is involved in immune receptor signaling. Syk is a tyrosine kinase that transduces signals from B cell receptors, Fc receptors, integrin signaling, and C-type lectin receptors. It is a convergence point for multiple immune activation pathways.
How may the rs7118 variant relate to Long COVID or ME/CFS?
Syk mediates platelet activation through CLEC2 and FcγRIIA, relevant to Long COVID coagulopathy. Its role in both B cell activation and platelet function makes SYK variants potentially important for multiple Long COVID pathological mechanisms.
Can a consumer DNA test detect the rs7118 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.
