What is the rs11720524 variant?

rs11720524 is a SNP (single nucleotide polymorphism) in the SCN5A (Sodium Voltage-Gated Channel Alpha Subunit 5) gene. It belongs to the Autonomic category and is part of the Autonomic Nervous System biological cluster. SCN5A encodes Nav1.5, the predominant cardiac sodium channel that drives the cardiac action potential upstroke.

Biological role and pathway

This variant sits within the SCN5A gene, which is involved in the cardiac action potential 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.

rs11720524 and Long COVID / ME-CFS research

SCN5A variants may increase cardiac arrhythmia risk; myocarditis and cardiac inflammation from COVID-19 may exacerbate arrhythmic features in Long COVID.

Frequently asked questions

What is the rs11720524 variant in the SCN5A gene?

rs11720524 is a single nucleotide polymorphism (SNP) located in the SCN5A (Sodium Voltage-Gated Channel Alpha Subunit 5) gene, which is involved in cardiac action potential. SCN5A encodes Nav1.5, the predominant cardiac sodium channel that drives the cardiac action potential upstroke.

How may the rs11720524 variant relate to Long COVID or ME/CFS?

SCN5A variants may increase cardiac arrhythmia risk; myocarditis and cardiac inflammation from COVID-19 may exacerbate arrhythmic features in Long COVID.

Can a consumer DNA test detect the rs11720524 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.
