rs2070770

What is the rs2070770 variant?

rs2070770 is a SNP (single nucleotide polymorphism) in the MS4A1 (Membrane Spanning 4-Domains A1 (CD20)) gene. It belongs to the Lymphocyte category and is part of the Lymphocyte Biology biological cluster. MS4A1 encodes CD20, a B cell membrane protein regulated during B cell development and the target of anti-CD20 therapies.

Biological role and pathway

This variant sits within the MS4A1 gene, which is involved in the B cell signaling and activation pathway. Genes within the Lymphocyte Biology 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.
