Forty-nine patients, with schizophrenia or schizoaffective disorder and treated with clozapine (n = 22) or olanzapine (n = 27), were evaluated for fasting levels of C-peptide, insulin and blood glucose, homeostasis model assessment index for insulin resistance (HOMA-IR) and body mass index (BMI), and genotyped for the -1438A/G, -783A/G, 102T/C, and His452Tyr polymorphisms of the HTR2A gene.
The impact of HTR2C and HTR2A polymorphisms on body mass index (BMI), glucose-insulin homeostasis, and blood lipid levels was evaluated in 46 patients with schizophrenia or schizoaffective disorder and treated with olanzapine (n = 28) or clozapine (n = 18) for at least 6 months.
The goal of the present study was to test the association of allele C of T102CHTR2A polymorphism with suicidality in patients with schizophrenia or schizoaffective disorder.
