How to do Annotate the with allele frequency?

Question

[mvahed]

Hello everybody,

I have several VCF files from Dragen Germline Illumina(Map, Align, and sort), I want to know: Where I annotate the variants with the information about gene, function ( introns, non-coding, coding), and what the effect of the mutation is, and allele frequency?

I know VarSeq is a good App for me, but I do not access it, Do you have any suggestion?

Thank you.
