Same mutation from different samples are differently annotated in dbsnp database
I try to call mutations for several samples by using mutect2. For some samples (such as WES443), a mutation of interest (chr2:201113112 based on hg19) is successfully annotated in dbSNP database - rs121913500. But, the mutation in a sample (WES449) is not successfully annotated in dbSNP database.

I'm not sure what the problem is? Could someone please give me some suggestion?
