1. There was no significant genotypic association between rs4680 and clinical symptoms or cognitive function in Han Chinese patients with schizophrenia. Patients with GG at rs165599 scored significantly higher on the Stroop test, suggesting better cognitive performance after 8 weeks of treatment. The findings suggest that the COMT gene polymorphisms may influence the response to antipsychotic treatment. PMID: 29634613
2. These findings suggest that the association between COMT polymorphisms and cognitive functioning could be, at least in part, due to their association with varying levels of S-COMT. This is important as, unlike MB-COMT, the substrates targeted by S-COMT are likely to be intra-cellular rather than, like dopamine, located mainly in the synaptic vesicles or the extra-cellular space.
