rs72928474

What is the rs72928474 variant?

rs72928474 is a SNP (single nucleotide polymorphism) in the SFTPC (Surfactant Protein C) gene. It belongs to the Respiratory category and is part of the Respiratory & Lung Function biological cluster. SFTPC encodes surfactant protein C, essential for reducing alveolar surface tension and maintaining lung compliance.

Biological role and pathway

This variant sits within the SFTPC gene, which is involved in the pulmonary surfactant production pathway. Genes within the Respiratory & Lung Function 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.
