IL10 and metabolic syndrome: Furthermore, a decreasing risk of metabolic syndrome (MetS) was observed in response to increasing plasma stearic acid levels in “A” allele carriers of interleukin 1 beta (IL1B) SNP rs16944 (Pinteraction = 0.043), and in response to increasing plasma arachidonic acid levels in those with the “GG” genotype of interleukin 10 (IL10) SNP rs1800896 (Pinteraction = 0.007), in a sample of 301 participants from the HS-SP (79).
