Nacho Cabellero, a 3rd year bioinformatics PhD student at Boston University, explains about the genetic variant that causes the herb cilantro to taste like soap to 10% of those who had their genetics analyzed through 23andMe, himself included.
The first time I tried cilantro I didn’t realize it; I just thought somebody had emptied a bottle of Old Spice on my pizza in an attempt to poison me. Cilantro tastes like soap to approximately 10% of the people who have had their genotype analyzed by 23andMe. The currently accepted explanation is that those of us who passionately despise cilantro were born with a genetic variant known as a single-nucleotide polymorphism (or SNP, pronounced ‘snip’)…The cilantro SNP is called rs72921001, and apparently, its genomic location lays close to a cluster of olfactory receptor genes that includes OR6A2, the gene most likely to be alerting our brain about the presence of cilantro.
