Here I have a CSQ field of a variant. What does '&' mean here: 3.31236e-05&7.19867e-02,T ?

what is the definition header for INFO=<ID=CSQ ? what are the column corresponding to your annotation ?

I'm sorry, I don't understand what you mean. Do you perhaps mean this?:

##INFO=<ID=CSQ,Number=.,Type=String,Description="Consequence annotations from Ensembl VEP. Format: Allele|Consequence|IMPACT|SYMBOL|Gene.....|goNl|goNl_AF|kaviar|kaviar_AF|gnomAD|gnomAD_AF">

yes (my messsage was messed-up by the biostar engine) , what is the column in the header corresponding to 3.31236e-05&7.19867e-02 ?

It is the gnomAD_AF I don't understand the format: AF1&AF2,T

is it this variant ? https://gnomad.broadinstitute.org/variant/1-96806-C-T

ADD REPLYlink written 8 months ago by Pierre Lindenbaum127k

yes sir: rs868804354

ADD REPLYlink written 8 months ago by c.clarido50

I would have say that there are two alternative alleles at this position, or two values for genomes and exomes, but I don't even find the same AF values at that position in gnomad...
