Abstract Lung cancer is the leading cause of cancer death in men and the second leading cause of cancer death in women worldwide. FGFR is involved in a variety of cellular processes including angiogenesis, wound healing, tissue repair, and tumorigenesis. Recently, a common polymorphism in the transmembrane domain of the FGFR4 gene, Gly388Arg, has been reported to correlate with alteration of cell migration in vitro and with disease progression and/or survival in breast, colon, prostate and lung cancer. To evaluate the prognostic significance of the FGFR4 Gly388Arg polymorphism in lung cancer, we analyzed a case-control study of 110 lung cancer patients and 90 healthy control. Genomic DNA from whole-blood specimens was extracted using Salting-out method. Quality of DNA was evaluated by electrophoresis. To determine the distribution of FGFR4 Arg388 and FGFR4 Gly388 alleles in lung carcinoma patients, RFLP-PCR was used. In this study demonstrated that there was no relationship between polymorphism of FGFR4 Gly388Arg gene and lung cancer. Also, no significant relationship was observed between this polymorphism and clinical and pathological features of patients. It is suggested that the large casecontrol studies are needed to detect genetic determinants affecting patients’ prognosis, with the promise of targeting these putative genetic determinants to provide new therapeutic tools for patients with lung cancer.

Abstract Genetic studies, there is a potential association of RELN with some psychological
disorders such as Autism Spectrum Disorders (ASD) schizophrenia (SCZ). The RELN
gene is located on chromosome 7q22.1 and encodes a large secretory protein of the
extracellular matrix (Reelin). In the present case-control study, we intended to investigate
the relationship between the rs362746 polymorphism of RELN and schizophrenia in a
group of schizophrenic and healthy subjects from northeastern Iran.30 unrelated schizophrenic patients and 30 matched control subjects were recruited The samples
from the participants underwent PCR and sequencing for RELN genotype identification.he genotype distribution for  both study and control groups were not in Hardy–Weinberg equilibrium(P>0.05).However, it was found that the prevalence of
rs362746 polymorphism was significantly different between the groups. the present study supported the evidence that rs362746 polymorphism of RELN was a
genetic factor for schizophrenia susceptibility. However, there is a need for replication
studies on different populations and further investigations on the sex-specific association
of this gene with schizophrenia.

Abstract Diabetes mellitus (DM) is a major public health issue in worldwide. Type 2 diabetes does not have a clear pattern of inheritance, although many affected individuals have at least one close family member, such as a parent or sibling, with the disease. The KCNJ11 gene is a member of the potassium channel gene family. polymorphisms  in KCNJ11  result  in  neonatal  diabetes and congenital hyper-insulinaemia, wherein the E23K (rs5219) polymorphism is linked with diabetes susceptibility where the K allele plays an important role in insulin secretion. In this study, we evaluate the frequency of these polymorphisms in a Kurdish population of 85 with type 2 diabetes. E23K polymorphism of KCNJ11 gene was genotyped by PCR-RFLP method. heterozygous carriers for AG are more in non‑diabetic patients (P = 0.034).

Abstract Type 2 diabetes (T2D), formerly known as adult-onset diabetes, is characterized by high blood sugar, insulin resistance, and relative lack of insulin.Diabetic retinopathy, a secondary microvascular complication of diabetes mellitus, is the leading cause of blindness. There is extensive evidence that the pathologic ocular angiogenesis in diabetic retinopathy is regulated by the vascular endothelial growth factor-A (VEGF-A).The single nucleotide polymorphism (SNP) C936T (rs3025039) of the VEGF gene has been investigated in relation to cancer, endometriosis, and age-related macular degeneration. The relationship between the rs3025039 VEGF gene polymorphism and the risk of type 2 diabetic retinopathy in 80 DT2 patients was examined. No significant association was found between polymorphism C936T and type 2 diabetes. It is recommended that this study be repeated on a larger population.

Abstract HCV is a blood pathogen that affects approximately 180 million people worldwide. It has the ability to escape its host’s defense mechanism and is considered a resistant species. Toll-like receptors (TLRs) are a family of evolutionary receptors that have been identified by the diagnosis of pathogens as the main regulators of innate and acquired immune responses. Studies have shown that genetic changes in the TLR3 gene are associated with high susceptibility or resistance to immune and infectious diseases. In this study, the effects of the TLR3 gene single nucleotide polymorphism rs78726532 on susceptibility to HCV infections were examined. The association between this polymorphism and the risk of hepatitis C in 50 patients and 50 healthy subjects was investigated. The results revealed a significant relationship between polymorphism rs78726532 and hepatitis C infection (p = 0.002). Thus, it could have a therapeutic and predictive potential.

Abstract In many cancers, an increase in gene expression of DNMT3b has been reported. This enzyme inhibits the expression of many tumor suppressor genes through the methylation of the promoter sequence and plays a key role in the progression of cancer. In this study, the relationship between polymorphism rs406193 of this gene and the risk of prostate cancer in 60 samples was investigated. The results showed a significant association between genotype TT and the risk of prostate cancer (p=0.048). It is recommended that this study be repeated in larger populations and that the relationship between this polymorphism and gene expression be investigated.
