What is the rs4271071 variant?
rs4271071 is a SNP (single nucleotide polymorphism) in the BCL6 (BCL6 Transcription Repressor) gene. It belongs to the Adaptive Immunity category and is part of the Adaptive Immunity biological cluster. BCL6 is the master transcription factor of germinal center B cells and follicular helper T cells (Tfh). It represses DNA damage checkpoints and alternative differentiation programs to allow affinity maturation of antibodies.
Biological role and pathway
This variant sits within the BCL6 gene, which is involved in the germinal center reaction 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.
rs4271071 and Long COVID / ME-CFS research
Germinal center dysregulation in COVID-19 leads to impaired affinity maturation and potentially aberrant antibody responses. BCL6 variants affecting germinal center reactions may influence the quality of protective immunity and the propensity for autoantibody development in Long COVID.

Frequently asked questions
What is the rs4271071 variant in the BCL6 gene?
rs4271071 is a single nucleotide polymorphism (SNP) located in the BCL6 (BCL6 Transcription Repressor) gene, which is involved in germinal center reaction. BCL6 is the master transcription factor of germinal center B cells and follicular helper T cells (Tfh). It represses DNA damage checkpoints and alternative differentiation programs to allow affinity maturation of antibodies.
How may the rs4271071 variant relate to Long COVID or ME/CFS?
Germinal center dysregulation in COVID-19 leads to impaired affinity maturation and potentially aberrant antibody responses. BCL6 variants affecting germinal center reactions may influence the quality of protective immunity and the propensity for autoantibody development in Long COVID.
Can a consumer DNA test detect the rs4271071 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.
