rs9831208

What is the rs9831208 variant?

rs9831208 is a SNP (single nucleotide polymorphism) in the HCN4 (Hyperpolarization Activated Cyclic Nucleotide Gated Potassium Channel 4) gene. It belongs to the Cardiovascular category and is part of the Autonomic Nervous System biological cluster. HCN4 encodes the primary pacemaker channel in the sinus node (the 'funny current' If), which sets heart rate.

Biological role and pathway

This variant sits within the HCN4 gene, which is involved in the cardiac pacemaking / sinus node function 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.
