abstract

abstract   background: the disrupted-in-schizophrenia 1 (disc1) gene, on the chromosome position 1q42, was initially identified at the breakpoint of a balanced translocation, t(1,11)(q42.1q14.3), which segregated with major mental disorders in a large scottish family.   methods: our samples included 200 unrelated patients diagnosed with schizophrenia on the basis of dsm-iv criteria and 200 normal controls, which were gathered from iran. the allele and genotype frequencies of the polymorphism were determined using polymerase chain reaction-restricted fragment length polymorphism (pcr-rflp) and the data were analyzed by logistic regression test.   results: in this study we genotyped the rs821616 polymorphism (serin704cystein) located within exon 11 of the disc1 gene. the samples were matched on the basis of sex and ethnicity. we used the case control study to determine the possible association between the ser704cys (rs821616) polymorphism and schizophrenia. analysis of data in the samples, revealed no association between the rs821616 polymorphism and schizophrenia (or= 0.697, 95% ci= 0.47-1.033, p=0.072).   conclusion: in this study we did not find any association between the rs821616 snpand schizophrenia.

Study of the association between DRD2 Gene Ser311Cys and GSTM1 Gene polymorphism in Schizophrenia

Introduction: Schizophrenia is a mental disorder affecting 1% of the world's population. Two of genes have been recognized to be involved in development of this disease: DRD2 and GSTM1. Methods: This case-control study included 100 patients suffering from schizophrenia who referred to Yazd Neuropsychiatry Hospital. Also, 100 healthy patients without schizophrenia were selected as the control g...

the study of aaag repeat polymorphism in promoter of errg gene and its association with the risk of breast cancer in isfahan region

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...

Association of schizophrenia with the rs821633 polymorphism in the DISC1 gene among Han Chinese

BACKGROUND Previous studies report that various single nucleotide polymorphisms (SNP) in the Disrupted-in Schizophrenia 1 (DISC1) gene are closely associated with schizophrenia, but there are no studies that assess the relationship of age of onset of schizophrenia with these SNPs. OBJECTIVE Investigate the relationship between the rs821633 SNP in the DISC1 gene and the occurrence and age of o...

Association between the A1298C Polymorphism of the Methylenetetrahydrofolate Reductase Gene and Recurrent Spontaneous Abortion

Introduction: A factor known to cause thrombophilia in women with recurrent pregnancy loss (RPL) is the A1298C polymorphism of methylenetetrahydrofolate reductase gene (MTHFR). This study aimed to determine the association between RPL and this polymorphism in Iranian patients. Methods: In this case-control study, 30 patients with a previous history of two or more consecutive unexplained abortio...
