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.
chr2 209113112 rs121913500 C T . PASS DB;ECNT=1;HCNT=24;MAX_ED=.;MIN_ED=.;TLOD=136.60 GT:AD:AF:ALT_F1R2:ALT_F2R1:FOXOG:QSS:REF_F1R2:REF_F2R1 0/1:82,47:0.357:18:29:0.617:3162,1787:39:43
chr2 209113112 . C T . PASS ECNT=1;HCNT=8;MAX_ED=.;MIN_ED=.;TLOD=200.35 GT:AD:AF:ALT_F1R2:ALT_F2R1:FOXOG:QSS:REF_F1R2:REF_F2R1 0/1:59,61:0.531:36:25:0.410:2339,2447:31:28
I'm not sure what the problem is? Could someone please give me some suggestion?
