Moreover, in a meta-analysis, the Val66Met polymorphism was not associated with schizophrenia, whereas C270T showed a trend for association in a fixed model (p=0.036), but not in a random model (p=0.053).

We argue that while the Val66Met polymorphism may not be a major risk-conferring agent for the development of schiz</span>ophrenia per se, there is mounting evidence that the polymorphism modulates a range of clinical features of the illness, including age of onset, symptoms, therapeutic responsiveness, neurocognitive function and brain morphology.
