Gnomad MAF question

Question

[a615ebfb]

I know that alternative allele is not the same as a minor allele for many cases. I am looking for Minor Allele Frequency values (MAF) for gnomad data. How would I obtain that?

Looking at this page, I see Allele Frequency which is alternative allele frequency: https://gnomad.broadinstitute.org/variant/1-55051215-G-GA?dataset=gnomad_r4

Is there a way to convert Gnomad's allele frequency which is based on the alternative allele to minor allele frequency?

Thanks!

Minor allele freq for a biallelic site is basically whichever number is lesser. You can simply use the logic x > 0.5? 1-x : x to get the MAF. Might be more robust if you download the gnomad VCF and process it locally.
