Recently I am using Annovar to annotate my gVCF file generated by GATK. I am confused with some lines：
chr6 31324208 31324208 G 0 exonic HLA-B chr6 31324493 31324494 CA 0 exonic HLA-B chr6 31324494 31324497 AGGT 0 exonic HLA-B
The Alt field is 0 instead of "-" for deletion and other characters for SNP. What does these "0" Alt mean? Thank you

Thank you all. I am new to biostars. I don't known how to post my results properly either the table or the screenshot. I will try my best to illustrate this question.
Fro example: "chr6 31324208 31324208 G 0 exonic HLA-B"
The position is at : chromosome 6 ,start at 31324208 , end at 31324208 The reference is: G The alternative is: "0" instead of "-" any other characters (Here is the question part) The mutation is an exonic mutation The gene symbol is HLA_B
Others like:"chr3 38534292 38534296 CACAT 0 UTR3 ACVR2B NM_001106:c.9469_9473delins0 "
It seems like a deletion of AVVR2B gene, the reference is "CACAT", the alternative is "0"
Hope the question is clear.

Does not it mean, that alternative allele depth is zero? So it is mean, that you have only reference (ref) allele count? Can you copy/paste part of your gVCF?
I think
