Schizophrenia is a severe neuropsychiatric disorder with symptoms such as hallucination, delusion and mental disorder. It is a complex disorder, in which genetic components play a crucial role in its pathogenesis. Among candidate genes for schizophrenia, Neuregulin 1 (NRG1) gene is the most important gene,  association of which with the illness has been confirmed in several studies. Single nucl...

Introduction: Vitamin D fulfills its crucial role in cell proliferation and death through signal transduction into the nucleus by vitamin D receptor (VDR). Recent studies have depicted the association between VDR gene polymorphisms and different cancers, including breast cancer. This study attempted to consider the relationship between VDR gene polymorphisms and breast cancer risk among women i...

BackgroundAttention deficit hyperactivity disorder (ADHD), is a multifactorial disorder and converging evidence has implicated abnormalities of dopamine neurotransmission. The aim of this study was to examine the association of -141 polymorphisms in DRD2 gene with ADHA among Iranian-Azeri population.Materials and Methods A case–control association study included 153 patients with attention defi...

Background The pro-inflammatory cytokine, tumor necrosis factor-alpha (TNF-α), is a pathogenic element for a number of disorders. Previous studies have reported that the -1031 T/C and -238 G/A polymorphisms in the promoter region of the TNF-α gene are important factors in reproductive-related disorders. One of the most common gynecological diseases of women during the reproductive years is endo...

Background: Glaucomatous neuropathy is a type of cell death due to apoptosis. The p53 gene is one of the regulatory genes of apoptosis. Recently, the association between the p53 gene encoding for proline at codon 72 and primary open-angle glaucoma (POAG) has been studied in some ethnic groups. This study is the first association analysis of POAG and p53 codon 72 polymorphism in Iranian patients...

Mastitis is a costly disease of dairy cattle as it causes a loss in milk yield and milk quality in affected cows. Toll-like receptor (TLR) genes play a role in the host response to a variety of organisms including those inducing mastitis. In the present study, we investigated the polymorphism of TLR2, 4, 6 and 9 genes in Holstein cattle and ...
