Abstract

中心性漿液性網脈絡膜症に関わる遺伝子変異を発見 --日本人に多い特殊なタイプの加齢黄斑変性の原因も解明--. 京都大学プレスリリース. 2018-05-31.Central serous chorioretinopathy (CSC) is a common disease affecting younger people and may lead to vision loss. CSC shares phenotypic overlap with age-related macular degeneration (AMD). As recent studies have revealed a characteristic increase of choroidal thickness in CSC, we conducted a genome-wide association study on choroidal thickness in 3, 418 individuals followed by TaqMan assays in 2, 692 subjects, and we identified two susceptibility loci: CFH rs800292, an established AMD susceptibility polymorphism, and VIPR2 rs3793217 (P = 2.05 × 10−10 and 6.75 × 10−8, respectively). Case–control studies using patients with CSC confirmed associations between both polymorphisms and CSC (P = 5.27 × 10−5 and 5.14 × 10−5, respectively). The CFH rs800292 G allele is reportedly a risk allele for AMD, whereas the A allele conferred risk for thicker choroid and CSC development. This study not only shows that susceptibility genes for CSC could be discovered using choroidal thickness as a defining variable but also, deepens the understanding of differences between CSC and AMD pathophysiology.
