Unfortunately, these studies have produced conflicting results.In a previous report, Shifman et al. found a three-marker haplotype (rs737865-rs4680-rs165599) that showed significant association with schizophrenia.

To assess the genetic contribution of other COMT variants to SZ susceptibility, we investigated three single-nucleotide polymorphisms (SNPs) (rs737865, rs4633, rs165599) in addition to the Val/Met variant (rs4680) in a highly selected sample of Australian Caucasian families containing 107 patients with SZ.

We find that P50 and PPI may be influenced by COMT rs4680 polymorphisms in schizophrenia; more excitingly, we find that P50 might be influenced by COMT rs737865 polymorphisms and PPI may be influenced by COMT rs165599 polymorphisms in schizophrenia, and their mutations are associated with the reduction of the risk of P50 or PPI defects in schizophrenia.

To assess this view, the authors conducted a case-control association study (399 patients with schizophrenia and 440 control subjects) for five functional polymorphisms (rs2075507, rs737865, rs6267, rs4680 and rs165599) in Japanese subjects.

Using the NIMH sibling study (SS), a non-independent case-control set, and an independent German (G) case-control set, we performed conditional/unconditional logistic regression to test for epistasis between SNPs in COMT (rs2097603, Val158Met (rs4680), rs165599) and polymorphisms in other schizophrenia susceptibility genes.

The SNP rs165599, which has been mapped to the 3'-UTR region of the COMT gene, was significantly associated with schizophrenia in our family study, and possibly associated with the age of onset, delusion/hallucination symptom dimension, and CPT performance.

In this updated meta-analysis, no evidence was found for an association between Val108/158Met polymorphisms, rs6267, rs165599, and haplotypes (rs7378655-rs4680-rs165599) and schizophrenia, although rs2075507 and rs737865 showed trends for significance in allele-wise analyses (P=0.039 in a multiplicative model, P=0.025 in a recessive model for rs2075507, P=0.018 in a dominant model for rs737865, uncorrected).

A recent study found, in a large sample of Ashkenazi Jews, a highly significant association between schizophrenia and a particular haplotype of three polymorphic sites in the catechol-O-methyl transferase, COMT, gene: an IVS 1 SNP (dbSNP rs737865), the exon 4 functional SNP (Val158Met, dbSNP rs165688), and a downstream SNP (dbSNP rs165599).
