How to compare haplotype with a list of nucleotide variations

Question

[seta]

Hi all,

I am trying to predict blood group from whole genome sequencing data (human); I found that this database is helpful. To this end, after variant calling and phasing vcf file, the haplotypes should be extracted and compared with information in the above-mentioned database, yes? Could you please tell me how I can compare the haplotypes with the list of nucleotide variations (available in the database) to get the corresponding blood group?

Please kindly share me any suggestions and comments.

Thanks
