Analysis of LOXL1 single nucleotide polymorphisms in Polish population with pseudoexfoliation syndrome.

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.
