A team study on the relationship between genetic polymorphisms of IL1A and IL1B and thyroid cancer in the Chinese Han population showed that IL1Ars3783521 was a risk factor for thyroid cancer, and rs3136558 and rs1143623 in the IL1B gene suggested susceptibility to the disease in patients older than 48 years (38). This evidence concerns the gene IL1B and thyroid gland carcinoma.
