rs#### or SNP-###

Question

[Giulia.cosenza]

Hi everyone, I'm working with a VCF file and I've noticed that there are 2 types of POSITION ID, the rs code, which is "rs" followed by a number, or an ID like 'SNP-' followed by a series of number. Is there a difference between the two IDs? Do they refer to something different or are they just two different ways to name the same nucleotide position?

I've tried to search both on the Genome Data Browser (https://www.ncbi.nlm.nih.gov/genome/gdv/?org=homo-sapiens) and I managed to find the rs ID but not with the SNP-###. If I use the corresponding position coordinates of the SNP-### the browser shows me te variant and its rs ID, not the SNP-### ID.

thank you for your help

Giulia

your SNP identifiers have been added with a tool without any link to any database. For example, omething like bcftools annotate --set-id.
