ABSTRACT. The aim of this study was to identify disease-associated loci in oldest old Han Chinese with atrophic age-related macular degeneration (AMD). This genome-wide association study (GWAS) only included oldest old (≥95 years old) subjects in Rugao County, China. Thirty atrophic AMD patients and 47 age-matched non-AMD controls were enrolled. The study subjects underwent a complete ophthalmic examination. Genomic DNA was extracted from peripheral blood samples. Single nucleotide polymorphisms (SNPs) were scanned by Genome-Wide Human Mapping SNP 6.0 Arrays and GeneChip Scanner 3000 7G. The results were read and analyzed by the Affymetrix Genotyping Console software. We filtered out the SNPs with a no-call rate ≥10%, MAF P < 0.05, and HWE P < 0.001. The remaining 561,277 SNPs were included in the association analysis. We found that the following 2 SNPs had the highest association with atrophic AMD: rs7624556 (located on 3q24) and rs13119914 (located on 4q34.3). In conclusion, we identified two atrophic AMD-associated SNPs (rs7624556 and rs13119914) in an oldest old Han Chinese population. 17433SNP analysis for oldest old patients with atrophic AMD
