Melanocortin-4 receptor gene variants are not associated with binge-eating behavior in nonobese patients with eating disorders
We aimed to determine whether variability in the melanocortin-4 receptor (MC4R) gene, predisposing to hyperphagia and obesity, may also be present in nonobese patients with binge-eating behavior or be related to anthropometric or psychopathological parameters in these patients. The coding region of the MC4R gene was sequenced in nonobese patients with binge-eating behavior diagnosed with bulimia nervosa or binge-eating disorder (n=77); individuals with severe early-onset obesity (n=170); and lean women with anorexia nervosa (n=20). A psychometric evaluation (Eating Disorders Inventory-2 and Symptom Checklist 90 Revised inv...

Association study of the SLITRK5 gene and Tourette syndrome
In this study, we tested the SLITRK5 gene as a candidate for TS in a family-based sample with 377 affected children. Using single nucleotide polymorphisms tagging the gene, we did not find any evidence supporting the association of TS and SLITRK5. (Source: Psychiatric Genetics)

Family-based association study of the arsenite methyltransferase gene (AS3MT, rs11191454) in Korean children with attention-deficit hyperactivity disorder
We examined the association between the selected polymorphisms in two candidate genes, the arsenite methyltransferase gene (AS3MT, rs11191454) and the inter-α-trypsin inhibitors heavy chain-3 gene (ITIH3, rs2535629), and attention-deficit hyperactivity disorder (ADHD) in a Korean population. A total of 238 patients with ADHD, along with both of their biological parents, were recruited. The children were administered intelligence quotient tests, whereas their parents completed the Child Behavior Checklist. In the transmission disequilibrium test on 181 trios, we found overtransmission of the A allele at the AS3MT rs1119145...

Common variants at Bin1 are associated with sporadic Alzheimer’s disease in the Han Chinese population
Conclusions: To the best of our knowledge, our study is the first to confirm the association of the variant rs7561528 adjacent to Bin1 with SAD in a Han Chinese Population. (Source: Psychiatric Genetics)

GRIN2B mediates susceptibility to intelligence quotient and cognitive impairments in developmental dyslexia
Conclusion: Our results add further evidence in support of GRIN2B contributing toward DD and deficits in DD. More specifically, our data support the view that GRIN2B influences DD as a categorical trait and its related quantitative phenotypes, thus shedding further light on the etiologic basis and the phenotypic complexity of this disorder.

Association between the TPH1 A218C polymorphism and antidepressant response: evidence from an updated ethnicity, antidepressant-specific, and ethnicity–antidepressant interaction meta-analysis
Conclusion: The TPH1 A218C polymorphism may not be associated with antidepressant response either in an ethnicity, antidepressant-specific population or in an ethnicity–antidepressant interaction model. (Source: Psychiatric Genetics)

Genetic association between the DRD4 promoter polymorphism and clozapine-induced sialorrhea
The use of clozapine, an effective antipsychotic drug used in treatment-resistant schizophrenia, is associated with adverse effects. Sialorrhea is one such effect, which can be distressing for many patients. Studies on the pharmacogenetics of the adverse effects of clozapine are limited. The aim of the present study was to determine whether clozapine-induced sialorrhea is associated with a 120 base-pairs (bp) tandem duplication polymorphism in the dopamine receptor subtype D4 (DRD4) gene. Ninety-five patients, mean age 35.43±9.43 years, with treatment-resistant schizophrenia and on clozapine were included in the study. De...

Association between autism spectrum disorder in individuals with velocardiofacial (22q11.2 deletion) syndrome and PRODH and COMT genotypes
Velocardiofacial (VCFS; 22q11.2 deletion) syndrome is a genetic disorder that results from a hemizygous deletion of the q11.2 region on chromosome 22, and is associated with greatly increased risk for psychiatric disorders, including autism spectrum disorder (ASD) and schizophrenia. There is emerging evidence for the involvement of catechol-O-methyltransferase (COMT) and proline dehydrogenase (oxidase) 1 (PRODH) in the psychiatric phenotype of individuals with VCFS. Here, we tested the hypothesis that PRODH and COMT are associated with ASD in youths with VCFS. We found that individuals with VCFS and the low-activity allele...
