I'm currently in an internship in a research group for Alzheimer's disease. I have to look for some big data to download with SNPs associated to Alzheimer. Do you have any idea, where I can find such data? I think dbSNP could be a good database and you can download some files via ftp, but I'm not sure, if there are files with SNPs associated with Alzheimer. I downloaded the file from snp4disease, but there are only ~2900 entries. For our research, I had to look for studies with many patients, but I'm not sure where to look for it. If you know, where I can find such big data (and to download it), please let me know. I need the information to calculate a linkage disequilibrium.
