Abstract:

A single nucleotide polymorphism (SNP) in CD24 has been associated with multiple sclerosis (MS) in a population based study. This SNP results in the replacement of alanine (CD24A) by valine (CD24V) at amino acid 57 in the resulting polypeptide chain. In the current study, the genotyping of this SNP and its contribution to MS in 217 patients and 200 healthy individuals of an Iranian population was investigated. The correlation of the SNP alleles with the progression of the disease was determined using the expanded disability status scale (EDSS) and progression index (PI). The data revealed that individuals with the CD24V/V genotype showed a 2-fold increase in the relative risk of MS compared to patients with the CD24A/V (0.27) and CD24A/A (0.25) genotypes (P = 0.0193, Odds Ratio 2.4882, 95% CI: 1.416-4.3722). Moreover, the progression of the disease in patients with CD24V/V was much faster than other patients that were examined by ANOVA and the least significant difference (LSD) test. However, in the CD24V/V patients LSD analysis was statistically significant (p

Association of two polymorphisms in MSH2 and XRCC1 genes with multiple sclerosis in Iranian population

Introduction: To protect genomes of all organisms from internal and external damages and maintain the genome integrity and the continuity of life, repair system has been developed in all living cells. Defects in repair system are responsible for various kinds of disease including cancers and neurodegenerative diseases such as Multiple sclerosis (MS). The relationship between various compone...

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...

IL-33 polymorphism rs1929992 and its association with susceptibility to different pattern of multiple sclerosis

Background: Multiple sclerosis is the most common autoimmune demyelinating disease of the central nervous system (CNS). Interleukin-33 (IL-33) is a cytokine with both pro-inflammatory and anti-inflammatory activities that implicated in the pathogenesis of some autoimmune diseases. The aim of this study was to determine single nucleotide polymorphism (SNP) of IL-33, rs1929992, in patient’s gene ...

Association Between MTHFR Genetic Variants and Multiple Sclerosis in a Southern Iranian Population

Multiple sclerosis (MS) is a demyelinating neuro- inflammatory autoimmune disease of the central nervous system. Genetic predisposition has long been suspected in the etiology of this disease. The association between MTHFR polymorphisms and MS has been ivestigated in different ethnic groups. We investigated the association between MTHFR C677T and A1298C missense variants and MS in 180 patients ...
