rs3793784, a SNP upstream of the ERCC6 DNA repair gene, has been linked independently and in conjunction with another SNP (rs380390) to age related macular degeneration. On it's own, the odds ratios for increased risk for heterozygotes and homozygotes, were, respectively, 1.51 (CI 1.07-2.11) and 1.60 (CI 0.99-2.61). In dbSNP orientation, individuals who are CFH gene SNP genotype rs380390(C;C) and are also rs3793784(G;G) for this (ERCC6) SNP are calculated to be at 23 fold higher risk for developing age related macular degeneration compared to individuals who are homozygous for the more common alleles (among Caucasians) at both loci (ie who are rs380390(G;G) and rs3793784(C;C). Genetic markers and biomarkers for age-related macular degeneration. ERCC6/CSB gene polymorphisms and lung cancer risk.

C;C

slightly increased risk of ARMD but if also rs380390(C;C) the risk is greatly increased, this should be automatically detected by gs134
