Lancet子刊:体检常见的“腔梗”,居然是个“遗传病”!

2021-04-06 MedSci原创 MedSci原创

腔隙性脑卒中有相当大的可遗传性成分,目前已确定的12个位点可代表未来的治疗目标。这些位点提供了对裂隙性卒中发病机制的见解,突出了血压升高、吸烟史和2型糖尿病在疾病发展中的作用。

腔隙性脑梗死(LIS)是脑梗死的一大类,主要是指由大型脑动脉的单个穿通支闭塞引起的非皮质性小梗死(直径2-15mm)。这些分支呈锐角起自Willis环的大动脉、大脑中动脉(MCA)主干或基底动脉。

 

早在1901年,Marie就首次描述了与多发腔隙有关的临床综合征,其特征为可良好康复的突发偏瘫、特征性的小步步态、假性延髓麻痹甚至痴呆。

然而,随着CT和MRI的引入,反对“腔隙性状态”的声音越来越多。腔隙性假说的批判者们指出,缺乏腔隙性脑梗死的动物资料或动物模型,且已证实相当一部分腔隙性脑卒中有来源于心脏、主动脉或大动脉的栓子。

此外,有关腔隙性脑梗的遗传基础了解甚少,迄今只在16q24上确定了一个位点。那么我们是否能试图确定新的关联,并提供对该疾病的机制性见解呢?为此,来自英国玛丽女王大学脑科学专家进行了基因组研究,结果发表在最新的《柳叶刀》子刊Lancet Neurology杂志上。

研究人员对新招募的MRI确诊为腔隙性脑梗的患者和现有的全基因组关联研究(GWAS)的数据进行了汇总分析。患者来自英国的医院,为英国DNA脑卒中研究以及国际卒中遗传学联盟的受试者。

病例和对照组首先按人种分层并进行两个荟萃分析,随后进行GWAS的多特征分析,与脑白质增生(一种病因相关的放射学特征)的研究联合分析,以发现额外的遗传关联。同时还进行转录组范围的关联研究(TWAS),以检测表达与裂隙性卒中相关的基因。

该荟萃分析包括来自欧洲、美国和澳大利亚的研究,包括7338例和254798例对照,其中2987例(与29540例对照相匹配)经MRI证实病灶。总的来说,在欧洲或跨民族荟萃分析中,发现5个位点(ICA1L-WDR12-CARF-NBEAL1、ULK4、SPI1-SLC39A13-PSMC3-RAPSN、ZCCHC14、ZBTB14-EPB41L3)与腔隙性脑梗发生相关。

另有7个位点(SLC25A44-PMF1-BGLAP、LOX-ZNF474-LOC100505841、FOXF2-FOXQ1、VTA1-GPR126、SH3PXD2A、HTRA1-ARMS2、COL4A2)在多特征分析中发现与脑白质增生相关。在已确定的位点中,有两个位点含有参与单源性脑卒中的基因(COL4A2和HTRA1)。

TWAS确定了6个基因(SCL25A44、ULK4、CARF、FAM117B、ICA1L、NBEAL1)的表达与腔隙性脑梗之间的关联。KEGG通路富集后显示主要与细胞外基质的破坏、PPD5磷酸化有关。孟德尔随机分析发现,血压升高、吸烟史和2型糖尿病与裂隙性脑梗正相关。

腔隙性脑卒中有相当大的可遗传性成分,目前已确定的12个位点可代表未来的治疗目标。这些位点提供了对裂隙性卒中发病机制的见解,突出了血压升高、吸烟史和2型糖尿病在疾病发展中的作用。
