rs1871894

What is the rs1871894 variant?

rs1871894 is a SNP (single nucleotide polymorphism) in the SOX9 (SRY-Box Transcription Factor 9) gene. It belongs to the Signaling category and is part of the Respiratory & Lung Function biological cluster. SOX9 encodes a transcription factor essential for chondrogenesis, testis determination, and lung and pancreas development.

Biological role and pathway

This variant sits within the SOX9 gene, which is involved in the cartilage and lung development / stem cell 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.
