PURPOSE: To assess the possible association of lysyl oxidase-like 1 (LOXL1) gene variants with pseudoexfoliation syndrome (PEX) in Polish population. METHODS: The group studied comprised of 36 patients with PEX (men and women) who presented to Department of Ophthalmology Collegium Medicum UMK in Bydgoszcz, Poland, and 30 control subjects. Blood samples were obtained from each patient via peripheral venipuncture, and genomic DNA was isolated according to the standard procedures. Three LOXL1 single nucleotide polymorphisms (SNPs) rs1048661 (R141L), rs3825942 (G153D) and rs216524 were genotyped in patient sample. RESULTS: The significant association with PEX was found for the G allele of rs3825942 (p = 0.0047) and for the T allele of rs216541 (p = 0.021). The haplotype (GGT) consisting of all three risk alleles was significantly overrepresented (87.5%) in patients with PEX. CONCLUSION: Single nucleotide polymorphisms in LOXL1 are associated with PEX in Polish population which confirms the association previously reported for Icelandic, Swedish, Indian and other populations.
