What is the rs3788015 variant?

rs3788015 is a SNP (single nucleotide polymorphism) in the PLCG2 (Phospholipase C Gamma 2) gene. It belongs to the Adaptive Immunity category and is part of the Adaptive Immunity biological cluster. PLCγ2 is activated by BTK and other tyrosine kinases downstream of immune receptors to generate IP3 and DAG, mobilizing calcium and activating PKC. Gain-of-function variants cause PLCG2-associated antibody deficiency and immune dysregulation (PLAID/APLAID).

Biological role and pathway

This variant sits within the PLCG2 gene, which is involved in the B cell 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.

rs3788015 and Long COVID / ME-CFS research

PLCG2 variants influence B cell and mast cell activation. The common rs72689236 protective variant is associated with lower Alzheimer's risk through microglial effects. In Long COVID neuroinflammation, PLCγ2 signaling in microglia may be relevant.

Frequently asked questions

What is the rs3788015 variant in the PLCG2 gene?

rs3788015 is a single nucleotide polymorphism (SNP) located in the PLCG2 (Phospholipase C Gamma 2) gene, which is involved in B cell signaling. PLCγ2 is activated by BTK and other tyrosine kinases downstream of immune receptors to generate IP3 and DAG, mobilizing calcium and activating PKC. Gain-of-function variants cause PLCG2-associated antibody deficiency and immune dysregulation (PLAID/APLAID).

How may the rs3788015 variant relate to Long COVID or ME/CFS?

PLCG2 variants influence B cell and mast cell activation. The common rs72689236 protective variant is associated with lower Alzheimer's risk through microglial effects. In Long COVID neuroinflammation, PLCγ2 signaling in microglia may be relevant.

Can a consumer DNA test detect the rs3788015 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.
