We read with great interest the letter to the editor by Mori et al. entitled “Stronger Association of CDKN2B-AS1 Variants in Female Normal-Tension Glaucoma Patients in a Japanese Population.” As pointed out in our original publication, the robust replication of genetic findings in independent populations is vital in understanding the significance of any reported association. Mori et al. have provided strong additional evidence for a sex-biased association with primary open-angle glaucoma (POAG) and normal-tension glaucoma (NTG) at this locus. This finding vastly improves confidence in the results in our original report.
