Abstract

BACKGROUND

Multiple sclerosis (MS) is a complex neurological disorder. Its aetiology involves both environmental and genetic factors. Recent genome-wide association studies have identified a number of single nucleotide polymorphisms (SNPs) associated with susceptibility to (MS). We investigated whether these genetic variations were associated with alteration in gene expression.

METHODS/PRINCIPAL FINDINGS: We used a database of mRNA expression and genetic variation derived from immortalised peripheral lymphocytes to investigate polymorphisms associated with MS for correlation with gene expression. Several SNPs were found to be associated with changes in expression: in particular two with HLA-DQA1, HLA-DQA2, HLA-DQB1, HLA-DRB1, HLA-DRB4 and HLA-DRB5, one with ZFP57, one with CD58, two with IL7 and FAM164A, and one with FAM119B, TSFM and KUB3. We found minimal cross-over with a recent whole genome expression study in MS patients.

DISCUSSION

We have shown that many susceptibility loci in MS are associated with changes in gene expression using an unbiased expression database. Several of these findings suggest novel gene candidates underlying the effects of MS-associated genetic variation.

摘要

背景

多发性硬化症(MS)是一种复杂的神经疾病。其病因涉及环境和遗传因素。最近的全基因组关联研究已经确定了一些与易感性(MS)相关的单核苷酸多态性(SNP)。我们研究了这些遗传变异是否与基因表达的改变有关。

方法/主要发现:我们使用源自永生外周淋巴细胞的 mRNA 表达和遗传变异数据库来研究与 MS 相关的多态性与基因表达的相关性。发现了几个与表达变化相关的 SNP:特别是两个与 HLA-DQA1、HLA-DQA2、HLA-DQB1、HLA-DRB1、HLA-DRB4 和 HLA-DRB5 相关,一个与 ZFP57 相关,一个与 CD58 相关,两个与 IL7 和 FAM164A 相关,一个与 FAM119B、TSFM 和 KUB3 相关。我们发现与最近的 MS 患者全基因组表达研究的交叉很少。

讨论

我们使用无偏倚的表达数据库表明,MS 中的许多易感性位点与基因表达的变化有关。其中一些发现提示了 MS 相关遗传变异作用下的新的候选基因。
