Despite the small sample size, 4 variants were novel, 2 of which p.(Cys5Trp) and p.(Thr293Met) were in the MYOC gene, and 2 p.(Asn51Thr), and p.(Gln142His) were in the OPTN. Notably, the OPTN p.(Asn51Thr) missense variant adjacent to the p.(Glu50Lys) variant, a well-known POAG pathogenic variant, was segregated from all proband’s family members with POAG. This evidence concerns the gene OPTN and open-angle glaucoma.
