To assess whether the IL1B gene confers increased susceptibility to schizophrenia, we conducted case–control and family‐based studies and an updated meta‐analysis.</p> </sec> <sec id="hup2365-sec-0002" sec-type="section"> <title>Methods</title> <p>We tested the association between IL1B and schizophrenia in 1229 case–control and 112 trio samples using 12 markers, including common tagging single nucleotide variations (SNVs) and a rare non‐synonymous variation detected by resequencing the coding regions. We also performed a meta‐analysis of rs16944 using a total of 8724 case–control and 201 trio samples from 16 independent populations.</p> </sec> <sec id="hup2365-sec-0003" sec-type="section"> <title>Results</title> <p>We found no significant associations between any of the 12 SNVs examined and schizophrenia in either case–control or trio samples.
