Hi,

I checked a few variant allele frequencies but I got different result from different websites. I checked my variances in NHLBI Exome Sequencing Project (ESP) and also check with this site from System Biology.

For example for the following variance I got MAF = 0.43 from ESP and MAF < 0.01 from Kaviar!

Can anybody tell me the popular and academic accepted way of reporting allele frequency in papers?

You can run your variants through Ensembl's VEP, which reports the following columns (as of VEP v81)

GMAF - Non-reference allele and frequency of existing variant in 1000 Genomes
AFR_MAF - Non-reference allele and frequency of existing variant in 1000 Genomes combined African population
AMR_MAF - Non-reference allele and frequency of existing variant in 1000 Genomes combined American population
ASN_MAF - Non-reference allele and frequency of existing variant in 1000 Genomes combined Asian population
EAS_MAF - Non-reference allele and frequency of existing variant in 1000 Genomes combined East Asian population
EUR_MAF - Non-reference allele and frequency of existing variant in 1000 Genomes combined European population
SAS_MAF - Non-reference allele and frequency of existing variant in 1000 Genomes combined South Asian population
AA_MAF - Non-reference allele and frequency of existing variant in NHLBI-ESP African American population
EA_MAF - Non-reference allele and frequency of existing variant in NHLBI-ESP European American population

Hi, Cyriac

I checked My variants in ensemble but all MAF fields are filled with - unfortunately no value reported there. You can see my result here on Ensembl.
