abstract：:Several studies suggest increased activity of phospholipase A2 in schizophrenic patients. In the present study, variants of four genes coding for phospholipase A2 enzyme groups (sPLA2, cPLA2, iPLA2 and PAFAH) were analysed in a case-control sample using 240 schizophrenic patients and 312 healthy controls. No differenc...
