The contribution of common tandem repeats (TR) variants to common, complex disease remains unknown, especially in populations historically underrepresented in genetic research. We identified common TR variants associated with risk of primary open-angle glaucoma (POAG) in individuals of African ancestry. The POAG-associated TR variants were predominantly found at Alu poly(A) tail elements, regions, retinal development enhancers, and harbor binding sites of a POAG-associated transcription factor, LMX1B, suggesting a convergent mechanism of how common TR variation arises and contributes to POAG pathophysiology.
常见串联重复序列(TR)变异对常见复杂疾病的影响尚不清楚,尤其是在遗传研究中历史代表性不足的人群中。我们在非洲裔个体中鉴定出与原发性开角型青光眼(POAG)风险相关的常见TR变异。与POAG相关的TR变异主要存在于Alu poly(A)尾元件、区域、视网膜发育增强子中,并含有POAG相关转录因子LMX1B的结合位点,这提示了常见TR变异产生并导致POAG病理生理的一种趋同机制。
