What is the rs5020736 variant?
rs5020736 is a SNP (single nucleotide polymorphism) in the KCNMA1 (Potassium Calcium-Activated Channel Subfamily M Alpha 1 (BKCa)) gene. It belongs to the Autonomic category and is part of the Autonomic Nervous System biological cluster. KCNMA1 encodes the BKCa channel, which regulates vascular smooth muscle tone, neuronal excitability, and aldosterone secretion.
Biological role and pathway
This variant sits within the KCNMA1 gene, which is involved in the calcium-activated potassium signaling pathway. Genes within the Autonomic Nervous System 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.
rs5020736 and Long COVID / ME-CFS research
KCNMA1 variants affecting vascular tone may contribute to blood pressure dysregulation and dysautonomia in Long COVID.
