What is the rs1876057 variant?
rs1876057 is a SNP (single nucleotide polymorphism) in the KIT (KIT Proto-Oncogene Receptor Tyrosine Kinase (CD117)) gene. It belongs to the Immune Signaling category and is part of the Histamine & MCAS biological cluster. KIT encodes the SCF receptor (CD117), expressed on mast cells, where it controls survival, proliferation, and activation.
Biological role and pathway
This variant sits within the KIT gene, which is involved in the stem cell factor / mast cell survival pathway. Genes within the Histamine & MCAS 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.
rs1876057 and Long COVID / ME-CFS research
KIT variants (especially D816V in mastocytosis) affect mast cell survival and activation; common variants may affect basal mast cell activity and susceptibility to mast cell activation in Long COVID.

Frequently asked questions
What is the rs1876057 variant in the KIT gene?
rs1876057 is a single nucleotide polymorphism (SNP) located in the KIT (KIT Proto-Oncogene Receptor Tyrosine Kinase (CD117)) gene, which is involved in stem cell factor / mast cell survival. KIT encodes the SCF receptor (CD117), expressed on mast cells, where it controls survival, proliferation, and activation.
How may the rs1876057 variant relate to Long COVID or ME/CFS?
KIT variants (especially D816V in mastocytosis) affect mast cell survival and activation; common variants may affect basal mast cell activity and susceptibility to mast cell activation in Long COVID.
Can a consumer DNA test detect the rs1876057 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.
