In dbSNP, the variant/pathogenic allele for rs62642941 is the deletion allele. However, even though they use the same identifier, the (I;I) genotype as defined by 23andMe appears to be the homozygote minor genotype causative for phenylketonuria. All other companies correctly assign this (I;I) genotype for the completely normal genotype, which is magnitude 0.
