Congenital factor XIII deficiency is a very rare bleeding disorder, but because of the high rate of consanguineous marriages, it is common in Sistan and Baluchestan Province of Iran. The discovery of promoter hypermethylation of numerous miRNAs in human diseases has demonstrated an epigenetic mechanism for aberrant miRNA expression. The present study has analyzed methylation and expression status of miR-185 and miR-132 genes in patients with inherited factor XIII deficiency in a sample of South-Eastern Iranian population. Promoter methylation of miR-185 and miR-132 was investigated by Methylation Specific Polymerase Chain Reaction (MS PCR) in blood samples of 75 factor XIII deficient individuals and 74 healthy controls. Expression level of these genes was also assessed in 15 blood samples of patients and 15 healthy controls using real-time quantitative reverse transcription PCR. Analysis of miR-132 and miR-185 promoter hypermethylation did not show any significant difference between cases and controls. Relative gene expression analysis in cases (n=15) with congenital factor XIII deficiency and healthy controls (n=15) revealed no statistically significant relationship for miR-132 (p = 0.126) and miR-185 (p = 0.165) genes. Our findings indicated that promoter methylation as well as gene expression of miR-132 and miR-185 had no significant effect on etiology of factor XIII deficiency.

Schizophrenia is a sophisticated mental disability which has affected nearly1.1% of people all over the world. According to recent researches, the key proteins triggered in the immune system are cytokines which might also be taking part in the pathogenesis of schizophrenia. The aim of this study was to evaluate the relationship between the -1082G/A and +874T/A polymorphisms of IL-10 and IFN-γ genes, respectively, in patients with schizophrenia. Materials and Methods: Total of 94 schizophrenic patients and 97 individuals as control samples were enrolled in this study. All samples were genotyped by amplification mutation refractory system-polymerase chain reaction (ARMS PCR) for candidate SNPs in IFN-γ and IL-10 genes. Results: No significant association was found among various genotypes of IFN-γ and IL-10 in selected SNPs with risk of schizophrenia, As well as there was no significant variation in allelic frequency of IFN-γ and IL-10 genes with the risk of disease. Conclusion: These data suggest that the -1082G/A of IL-10 and +874T/A IFNγ genes are not involved in the development of schizophrenia risk. To validate of this data, suggesting more studies in diverse populations with larger sample size.
