Progression of age-related macular degeneration (AMD), the leading cause of blindness in the elderly, was followed in a cohort of 238 individuals from a single center. Individuals with an epsilon (epsilon)2 genotype (c.526C>T of reference sequence NM_000041.2) of the apolipoprotein (APOE) gene were found to be strongly associated with disease with a significant 4.8-fold increased relative risk compared to individuals with an epsilon4 genotype (c.388T>C of reference sequence NM_000041.2) (odds ratio [OR], 4.8; 95% confidence interval [CI], 1.19-19.09) and a nearly significant three-fold increased relative risk compared to individuals with an epsilon3 genotype (reference sequence NM_000041.2) (OR, 2.8; 95% CI, 0.96-19.09). This finding was present only in females who progressed with AMD, which suggests that there may be a gender-specific role in progression of AMD in individuals with an epsilon2 allele. A gender-related factor is therefore implicated either directly or indirectly in the AMD disease process.
在一个来自单一中心的238人队列中,对年龄相关性黄斑变性(AMD,老年人失明的主要原因)的病情进展进行了跟踪研究。研究发现,与载脂蛋白(APOE)基因ε4基因型(参考序列NM_000041.2的c.388T>C)个体相比,载脂蛋白(APOE)基因ε2基因型(参考序列NM_000041.2的c.526C>T)个体与疾病的关联性很强,相对风险显著增加4.8倍(比值比[OR]为4.8;95%置信区间[CI]为1.19 - 19.09),与ε3基因型(参考序列NM_000041.2)个体相比,相对风险增加近3倍(OR为2.8;95% CI为0.96 - 19.09)。这一发现仅在病情进展的AMD女性患者中存在,这表明ε2等位基因个体的AMD病情进展可能存在性别特异性作用。因此,一个与性别相关的因素直接或间接参与了AMD疾病进程。
