How to find the Allele Number (AN) of a variant not reported on gnomAD
If there is a variant not reported on gnomAD, is there a way to determine the allele number to confirm how many people were sampled, and were not found to have that variant for a given chromosomal location?

Is this variant probably an artifact?

You need to check with the gnomAD team - I'm not sure if they are the primary source for any of the data or they just reprocess sequencing data from other sources. If the latter is the case, you'll have to contact the primary sources.
at least for gnomad v3 the allele number is generally around 152,000 for variants they do see, so I would imagine that number would suffice for loci that have no reported variants
