Association of VAMP-2 and Syntaxin 1A Genes with Adult Attention Deficit Hyperactivity Disorder
Ay˚e Nur Inci Kenar,Özlem I˙zci Ay,Hasan Herken,Mehmet Emin Erdal 대한신경정신의학회 2014 PSYCHIATRY INVESTIGATION Vol.11 No.1
Objective The etiology of attention deficit hyperactivity disorder (ADHD) has not been entirely clarified yet. Structural and metabolicdifferences at the prefrontal striatal cerebellary system and the interaction of gene and environment are the main factors that thought toplay roles in the etiology. Genetic investigations are performed especially about the dopamine pathways and receptors. In this study; itwas aimed to investigate the association of the synaptobrevin-2 (VAMP-2) gene Ins/Del polymorphism and syntaxin 1A gene intron7 polymorphism, which take place in encoding presynaptic protein, with adult ADHD. Methods One hundred thirty-nine patients, having ADHD aging between 18 and 60 years and 106 healthy people as controls were includedinto the study. DNA samples were extracted from whole blood and genetic analysis were performed. ResultsaaA significant difference was determined between ADHD and VAMP-2 Ins/Del polymorphism and syntaxin 1A intron 7 polymorphismaccording to the control group. These polymorphisms were found not to be associated with subtypes of ADHD. Conclusion It is supposed that synaptic protein genes together with dopaminergic genes might have roles in the etiology of ADHD.

Objective: The prevalence of schizophrenia is 1%, and it is a debilitating disorder that often results in a shortened lifespan. Peripheral blood samples are good candidates to investigate because they can be easily drawn, and they are widely studied in psychiatric disorders. MicroRNAs are small non-coding RNA transcripts. They regulate the expression of genes by binding to the 3’-untranslated region (UTR) of mRNAs and pointing them to degrade. In this study, we aimed to investigate the expression of miR-9-5p, miR-29a-3p, miR-106-5p, miR-106b-5p, miR-107, miR-125a-3p, and miR-125b-3p in schizophrenia patients and healthy controls. Methods: We collected blood samples from 16 patients with schizophrenia and 16 healthy controls. MicroRNAs were measured with reverse transcriptase polymerase chain reaction. Results: Schizophrenia patients showed statistically significant upregulation of five microRNAs: miR9-5p (p=0.002), miR29a-3p (p<0.001), miR106b-5p (p=0.002), miR125a-3p (p<0.001), and miR125b-3p (p=0.018). Conclusion: Our results increased the value of the miR106 and miR29 families as potentially and consistently dysregulated in psychiatric disorders. Our results should be considered preliminary, and they need confirmation in future studies with larger sample sizes.
