Beschreibung:
Glaucoma is a leading cause of irreversible blindness. A genome-wide search yielded multiple single-nucleotide polymorphisms (SNPs) in the 15q24.1 region associated with glaucoma. Further investigation revealed that the association is confined to exfoliation glaucoma (XFG). Two nonsynonymous SNPs in exon 1 of the gene LOXL1 explain the association, and the data suggest that they confer risk of XFG mainly through exfoliation syndrome (XFS). About 25% of the general population is homozygous for the highest-risk haplotype, and their risk of suffering from XFG is more than 100 times that of individuals carrying only low-risk haplotypes. The population-attributable risk is more than 99%. The product of LOXL1 catalyzes the formation of elastin fibers found to be a major component of the lesions in XFG.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thorleifsson, Gudmar -- Magnusson, Kristinn P -- Sulem, Patrick -- Walters, G Bragi -- Gudbjartsson, Daniel F -- Stefansson, Hreinn -- Jonsson, Thorlakur -- Jonasdottir, Adalbjorg -- Jonasdottir, Aslaug -- Stefansdottir, Gerdur -- Masson, Gisli -- Hardarson, Gudmundur A -- Petursson, Hjorvar -- Arnarsson, Arsaell -- Motallebipour, Mehdi -- Wallerman, Ola -- Wadelius, Claes -- Gulcher, Jeffrey R -- Thorsteinsdottir, Unnur -- Kong, Augustine -- Jonasson, Fridbert -- Stefansson, Kari -- New York, N.Y. -- Science. 2007 Sep 7;317(5843):1397-400.
