Diabetic retinopathy (DR) is a microvascular disease of the retina and the leading cause of visual disability in diabetic patients. Genetic factors have shown to play a pivotal role in DR onset, and several candidate genes have been associated with its progression. A literature search was performed to identify the genes known to be associated with DR through linkage analysis, candidate gene association, and genome-wide association studies (GWAS). A further literature search was performed to discover their potential connection with various biological pathways. A total of 65 genes were found and several of these genes belong to major signaling pathways known to play a significant role in DR, including systemic inflammation, angiogenesis, and neurogenesis. A comprehensive analysis presented in this review will be helpful in unraveling the role of genetics in the pathogenesis of DR.
糖尿病视网膜病变（DR）是一种视网膜的微血管疾病，也是糖尿病患者视力障碍的主要原因。遗传因素已被证明在 DR 的发病中起着关键作用，并且已经有几个候选基因与它的进展有关。通过连锁分析、候选基因关联和全基因组关联研究（GWAS），进行了文献检索以确定已知与 DR 相关的基因。进一步的文献检索发现了它们与各种生物途径的潜在联系。共发现了 65 个基因，其中一些基因属于主要信号通路，这些信号通路在 DR 中起着重要作用，包括全身炎症、血管生成和神经发生。本文综述中进行的综合分析将有助于揭示遗传在 DR 发病机制中的作用。
