LOXL1 and exfoliation syndrome: We obtained LOXL1 genotyping results from 71 patients with XFG (mean age ± SD, 74.7±7.4 years, 52.9% males), 54 patients with XFS (76.0±6.8 years, 35.2% males), 43 patients with POAG (69.2±9.0 years, 54.8% males), and 97 controls without exfoliation or glaucoma (74.8±7.5 years, 43% males; a few DNAs did not amplify or were limited in amount).
