Epiretinal membrane (ERM) is a common retinal condition characterized by the presence of fibrocellular tissue on the retinal surface, often with visual distortion and loss of visual acuity. We studied European American (EUR), African American (AFR), and Latino (admixed American, AMR) ERM participants in the Million Veteran Program (MVP) for genome-wide association analysis-a total of 38,232 case individuals and 557,988 control individuals. We completed a genome-wide association study (GWAS) in each population separately, and then results were meta-analyzed. Genome-wide significant (GWS) associations were observed in all three populations studied: 31 risk loci in EUR subjects, 3 in AFR, and 2 in AMR, with 48 in trans-ancestry meta-analysis. Many results replicated in the FinnGen sample. Several GWS variants associate to alterations in gene expression in the macula. ERM showed significant genetic correlation to multiple traits. Pathway enrichment analyses implicated collagen and collagen-adjacent mechanisms, among others. This well-powered ERM GWAS identified novel genetic associations that point to biological mechanisms for ERM.
视网膜前膜（ERM）是一种常见的视网膜疾病，其特征是视网膜表面存在纤维细胞组织，常伴有视觉扭曲和视力下降。我们在百万退伍军人计划（MVP）中研究了欧美裔（EUR）、非裔美国人（AFR）和拉丁裔（混血美国人，AMR）的ERM参与者，进行全基因组关联分析，共有38232例病例个体和557988例对照个体。我们分别在每个群体中完成了全基因组关联研究（GWAS），然后对结果进行了荟萃分析。在所研究的所有三个群体中均观察到全基因组显著（GWS）关联：EUR受试者中有31个风险位点，AFR中有3个，AMR中有2个，跨祖先荟萃分析中有48个。许多结果在芬兰基因样本中得到了重复。几个GWS变异与黄斑区基因表达的改变有关。ERM与多个性状显示出显著的遗传相关性。通路富集分析涉及胶原蛋白和与胶原蛋白相邻的机制等。这项样本量充足的ERM GWAS确定了新的遗传关联，这些关联指向了ERM的生物学机制。
