According to the GWAS catalog database, variants in SRBD1, LRPPRC and RAB37 genes have been reported to be associated with other phenotypes: SRBD1 rs3213787 has been associated with normal tension glaucoma[39], LRPPRC rs13387221 has been associated with cognitive ability (intelligence) in childhood[40] and RAB37 rs10512597 has been associated with fibrinogen levels[41,42]. This evidence concerns the gene LRPPRC and low tension glaucoma.
