I recently downloaded sliced variant .vcf files from gnomAD. Upon downstream analysis, I noticed that some of my variants were annotated to have no reported allele count or allele frequency... Does anyone know how this could be? I assumed that if there was no count for this allele, the allele would not be in the file?
