Annotation for SNPs that is not found in dbSNP

Question

[a_biologist]

Hi Guys,

I have a list of snps in which they have being annotated using Seattle-seq but with no rsID, how can I further annotated those snps as Seattle-seq doesn't tell me that much about the snps in terms of functional and biological knowledge, and is there a way I can search those snps to see if they have been involved in diseases?

Thanks a lot in advance for your help,

Best
