NOS1AP Gene

Nitric Oxide Synthase 1 Adaptor Protein (NOS1AP) is a gene involved in neuronal NOS / cardiac repolarization that has been studied in relation to immune function, metabolism, and chronic illness. Variants in NOS1AP may influence how the body responds to infection, inflammation, and long-term recovery.

What is the NOS1AP gene?

NOS1AP encodes nitric oxide synthase 1 adaptor protein, a protein involved in neuronal NOS / cardiac repolarization. It belongs to the Cardiovascular category and is part of the Autonomic Nervous System biological cluster. NOS1AP encodes a scaffolding protein that interacts with nNOS and regulates cardiac QT interval.

Biological role and pathway

NOS1AP is involved in the neuronal NOS / cardiac repolarization pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. 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 in these systems — particularly under conditions of physiological stress such as viral infection or prolonged illness.

NOS1AP and Long COVID / ME-CFS research

NOS1AP variants are the strongest common genetic determinants of QT interval variation; prolonged QT and cardiac arrhythmias are documented in Long COVID and POTS, making NOS1AP variants potentially relevant.
