Therefore, genetic variability in the components of DNA repair systems may influence the ability of the cell to cope with oxidative stress and in this way contribute to the pathogenesis of AMD. However, few reports have been published on this subject so far. We demonstrated that the c.977C&gt;G polymorphism (rs1052133) in the hOGG1 gene and the c.972G&gt;C polymorphism (rs3219489) in the MUTYH gene, the products of which play important roles in the repair of oxidatively damaged DNA, might be associated with the risk of AMD. Oxidative stress may promote misincorporation of uracil into DNA, where it is targeted by several DNA glycosylases. We observed that the g.4235T&gt;C (rs2337395) and c.\u221232A&gt;G (rs3087404) polymorphisms in two genes encoding such glycosylases, UNG and SMUG1, respectively, could be associated with the occurrence of AMD. Polymorphisms in some other DNA repair genes, including XPD (ERCC2), XRCC1 and ERCC6 (CSB) have also been reported to be associated with AMD. These data confirm the importance of the cellular reaction to DNA damage, and this may be influenced by variability in DNA repair genes, in AMD pathogenesis.<\/jats:p>","DOI":"10.3390\/ijms131013378","type":"journal-article","created":{"date-parts":[[2012,10,18]],"date-time":"2012-10-18T13:00:46Z","timestamp":1350565246000},"page":"13378-13397","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Genetic Variability in DNA Repair Proteins in Age-Related Macular Degeneration"],"prefix":"10.3390","volume":"13","author":[{"given":"Janusz","family":"Blasiak","sequence":"first","affiliation":[{"name":"University of Lodz, Faculty of Biology and Environmental Protection, Department of Molecular Genetics, Pomorska 141\/143, Lodz 90-236, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ewelina","family":"Synowiec","sequence":"additional","affiliation":[{"name":"University of Lodz, Faculty of Biology and Environmental Protection, Department of Molecular Genetics, Pomorska 141\/143, Lodz 90-236, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antero","family":"Salminen","sequence":"additional","affiliation":[{"name":"Department of Neurology, Institute of Clinical Medicine, University of Eastern Finland, Kuopio FI-70211, Finland"},{"name":"Department of Neurology, Kuopio University Hospital, Kuopio FI-70211, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kai","family":"Kaarniranta","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Institute of Clinical Medicine, University of Eastern Finland, Kuopio FI-70211, Finland"},{"name":"Department of Ophthalmology, Kuopio University Hospital, Kuopio FI-70211, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2012,10,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"15","DOI":"10.1007\/978-1-4614-0653-2_2","article-title":"Age-related macular degeneration","volume":"724","author":"Khandhadia","year":"2012","journal-title":"Adv.
