With no genes within or around GLC1H identified for glaucoma association yet, three intergenic single-nucleotide polymorphisms (SNPs) located on chromosome 2p16.3, just outside of GLC1H, have recently associated with susceptibility to POAG in an Afro-Caribbean population of Barbados, West Indies [12]. This evidence concerns the gene EFEMP1 and open-angle glaucoma.
