{Reference Type}: Journal Article {Title}: Lack of association between HTR4 gene polymorphisms and schizophrenia in case-control and family-based samples. {Author}: Hirata Y;Souza RP;Lieberman JA;Meltzer HY;Kennedy JL; {Journal}: Psychiatry Res {Volume}: 175 {Issue}: 1 {Year}: Jan 2010 30 {Factor}: 11.225 {DOI}: 10.1016/j.psychres.2009.08.005 {Abstract}: Previous studies have found haplotypic association of HTR4 variants and schizophrenia. Examining case-control pairs, G-G of rs7713886 was associated with schizophrenia risk. The A-A-G-G-G-A-A rs9325104-rs1422636-rs7715569-rs6873382-rs7711800-rs10078551-rs2068190 haplotype was overrepresented in the schizophrenia cases. The associations were no longer significant after corrections for multiple comparisons. No association was found in the family sample.
