Study-specific results are given in supplementary tables 11 and 12.
Locus assigned to the RefSeq protein-coding gene within or near the association signal interval (defined by LD plot using the measure r2 > 0.9 with the lead SNP implemented in SNAP using the CEU reference). The locus was assigned to the interval defined by the two flanking RefSeq protein-coding genes if clearly intergenic.
P values that are significant after correction for multiple testing (P < 0.001 for testing 26 independent SNPs in 2 diseases) are shown in bold.
Given the association between reduced CCT and elevated keratoconus or glaucoma risk, it is expected that the CCT-reducing allele is the keratoconus or POAG risk allele.
+, the effect direction is as expected; −, the effect direction is not as expected.
SNPs were not genotyped in the two keratoconus case-control studies and are therefore presented as missing values (NA).
