Hi, I am using gnomAD v 4.1 to estimate disease prevalence of a monogenic autosomal dominant disease. I have a list of possible rare pathogenic alleles (MAF \< 0.004%) and because the disease is a heterozygous disease, I …

Hello, I would really like to be able to get the details of the TERT variants that co-occur with TERT NM\_198253:c.-57A\>C in V4 if that is possible. Unfortunately this variant is only seen once in gnomad V2 so the search…

Hello, I’ve been looking at these 2 variants: I can’t quite understand the column headings – columns 2 and 4 seem to mean the same thing, and then the Likely co-occurrence pattern doesn’t seem to make sense accordi…
