PURPOSE OF REVIEW The genetic basis of primary angle closure (PAC) glaucoma is slowly being elucidated. In recent years, genome-wide association studies have identified eight new susceptibility loci for PAC. Our purpose in this review is to summarize our current knowledge of genetics in angle closure, to take a closer look at the eight novel loci and what we have learned about their function, and consider what they might teach us about angle closure disease. RECENT FINDINGS Multiple novel loci associated with PAC glaucoma have been identified in large genome-wide association studies. Moreover, primary open angle glaucoma and PAC glaucoma are found to have partly overlapping genetic features. SUMMARY The genetic basis of PAC glaucoma is being deciphered. Even though there is still much more to be uncovered, this process has already provided new insights in the pathogenesis of this blinding disease. A better understanding of the pathogenic mechanisms through genomics may be valuable for the development of novel therapies.
