Note that sST2/IL1RL1, which is located on human chromosome 2 and is a member of the IL-1R/Toll-like receptor (TLR)4 family (sST2, GeneID: 9173), is consistently confused with the protein suppression of tumorigenicity 2 (especially in the cardiovascular literature) which is located on human chromosome 11 (ST2, GeneID: 6761) and is associated with cancer. The gene discussed is IL1RL1; the disease is cancer.
