I have a list of SNPs from dbSNP build 150, I want to run a batch analysis on SIFT which uses an older build of rsid's (build 138 - if I'm not mistaken).
I understand that dbSNP rsids are updated based to avoid synonymous occurrences, but could someone please clarify on how would I map the rsids to an older build which is required by SIFT?
Is there any way of confirming the build for my current list of IDs?
Can different genome assemblies have the same rsIDs?
