Background

The STS2 gene belongs to the interleukin-1 receptor host defence and inflammation family, also known as IL1RL-1. It encodes for two isoforms: transmembrane receptor form (ST2L) and truncated soluble receptor form (sST2), which the latter being detectable in human serum. Elevated serum levels of sST2 have been linked to a variety of medical conditions, including cardiovascular disease, asthma, and sepsis. sST2 has been shown to be a reliable biomarker for heart failure. The median concentration of sST2 in healthy individuals is 18 ng/mL. The levels are affected by age and sex. sST2 concentration greater than 35 ng/mL strongly indicates hospitalization and death in heart failure (HF) patients (Presage ST2 assay, Critical Diagnostics). sST2 may also be useful for predicting the risk of death or hospitalization in patients with myocardial infarction (MI). Studies have shown that sST2 serum levels peak one day after a cardiac incident.
