<p>Association between polymorphisms of <em>LEP</em>,<em> LEPR</em>, <em>DRD2</em>, <em>HTR2A</em> and<em> HTR2C</em> genes and risperidone- or clozapine-induced hyperglycemia</p>

Abstract: Objective To determine whether genetic polymorphisms related to pharmacodynamics with metabolic adverse effects, namely leptin promoter ( LEP ) rs7799039, leptin receptor rs1137101, dopamine D2 rs4436578, serotonin 5-HT2A rs6313, and serotonin 5-HT2C rs518147 and rs12836771, are associated with hyperglycemia induced by risperidone or clozapine in adult Thai patients with psychosis. Methods A total of 180 patients treated with risperidone-based… Show more

“…CROSSOVER STUDIES FOR GENE-TREATMENT INTERACTION the gene effect size has little influence but on the standard error. Indeed, in agreement with our study, the sample size simulation studies by Cardon et al 25 and Puangpetch et al 26 highlighted the association between sample size ratios and the genetic model, frequency, and effect size. In a crossover design, baseline covariates not impacting the within-subject variability, have limited impact on the power to detect a treatment effect.…”

“…The protocol for DNA extraction has been described in our previous study. 35 Genotyping of the CETP polymorphisms was performed by conducting a TaqMan SNP genotyping assay on an Applied Biosystems ® ViiA™7 Real-Time polymerase chain reaction (PCR) System (ABI, Foster City, CA, USA). The extracted DNA was amplified through PCR by using the primers of CETP c.2490C>A, rs3764261; c.5454G>A, rs708272; and c.2327G>A, rs12149545.…”

“…In a recent study, the association between to carriage of the allele A SNV rs3828942 of LEP gene and disorders of carbohydrate metabolism development (an increase of the glucose concentration in a blood plasma for an empty stomach to a value above 6.1 mmol / L) in patients taking APs has also been presented [46]. Puangpetch A. et al (2019) investigated association between SNVs of candidate genes, in particular the SNVs rs7799039 of LEP gene and rs1137101 of LEPR gene, with metabolic disorders development in Thai schizophrenic patients receiving risperidone or clozapine. The authors discover that the prevalence of hyperglycemia is higher among patients treated with clozapine (64.0%) than among patients treated with risperidone (30.8%).…”

“…SNV (rs7799039) of LEP gene demonstrated a significant association with hyperglycemia development (χ2 = 9.879, p = 0.008) among patients receiving risperidone; patients with genotype AA have the highest risk of hyperglycemia developing (41.1%), and genotypes AG and GG -20.8% and 0%, respectively. None of SNV researched genes is associated with the risk of hyperglycemia developing in patients taking clozapine [47]. Klemettilä J.P. et al (2015) studied the role of leptin, adiponectin, and inflammatory cytokine levels in serum as possible biochemical markers of APs-induce weight gain.…”
