What's the difference between 'common' and 'somatic' SVs?

[yhx-tj]

Hi, I can see that pathogenic structural variations come from Clinvar, but what are common and somatic types of SVs?

How to understand 'variant calls are from germline samples only (no somatic)'?

And how can I get the actual breakpoints of each structural variation? Is it possible to know whether identical variant calls were derived from different individuals or from the same sample but as a result of different analyses?

Thanks!
