I'm working on a project to identify variants as being either germline or somatic based on nearby SNPs, and I was wondering if there were any databases of SNPs for Homo sapiens other than dbSNP? I'm not looking for databases that contain additional information (pathogenicity etc.) on SNPs that are already in dbSNP, instead I want to know if there are any other databases that contain SNPs that aren't found in dbSNP.
I've been searching online and so far the only databases I can find are either deprecated or integrated into dbSNP, so any suggestions would be great.
