Hi there! I have a question concerning a specific variant: 16-3731261-G-C. This variant is present once in v4.1.1., but is absent from v4.1.1. (non-UKB), leading me to believe it is in the UKB subset of gnomAD. Yet, the variant is not present in UKB (I’ve checked in several ways). Where could this discrepancy come from? Thanks in advance for your help! 
Thank you for reaching out. This variant is also present in the UK Biobank allele frequency browser: https://afb.ukbiobank.ac.uk/variant/chr16-3731261-G-C.
Exactly, which makes it even more interesting that it cannot be found in the Cohort Browser. Maybe because the Cohort Browser is WES data and the variant was only found in the WGS data? Although that is probably a question for UKB and not for on this forum thanks for the help!
