I found that the latest DB (downloadable here) have little discrepancies respect the website data displayed.
As example (exome data):
16-90162186-T-C DB allele frequency: 0.371754 vs website (https://gnomad.broadinstitute.org/variant/16-90162186-T-C) AF: 0.3775
12-133435716-T-G DB AF: 0.22511 vs website (https://gnomad.broadinstitute.org/variant/12-133435716-T-G) AF: 0.2241
and the same results for population and GENOMES data. Does anybody has got a clue?
Thanks a lot in advance for any help!
