Özet

Apolipoprotein E (apo E) is directly involved in the amyloid deposition and fibril formation and is present in many cerebral and systemic amyloidoses immunologically. It is encoded by a polymorphic gene and it has three common alleles - epsilon 2, epsilon 3, and epsilon 4. Exfoliation syndrome (XFS) is characterized by the deposition throughout the body of focal fibrillogranular aggregates in which there have been some reports of amyloid or amyloid-like features. We evaluated the possible association between apo E polymorphism and the occurrence of XFS. Using High Pure PCR Template Preparation Kits, genomic DNAs were extracted from whole blood and apo E polymorphisms were determined by using Lightcycler-Apo E Mutation Detection Kits in 76 patients with XFS and 74 controls. The E2/E2, E2/E3 and E2/E4 genotypes (OR 29.9, 95% CI 3.1-293.7: OR 56.1, 95% CI 12.5-252.7; OR 43.9, 95% CI 7.4-257.6, respectively) and the is an element of 2 allele are found to have an increased risk of developing XFS (p = 0.0001); whereas the is an element of 3 allele was found to be protective (p = 0.0001). Apo E polymorphism and the presence of is an element of 2 allele are seem to be significantly associated with the development of XFS. (c) 2005 Elsevier Ltd. All rights reserved.
