Besides cilantro, are there any other ingredients that have been identified to taste different to people based on their genetics?

Brussels Sprouts are regulated by TAS2R38, a.k.a. “the brussels sprouts gene”.

TAS2R38 controls the bonding of a specific chemical called phenylthiocarbamide (PTC). If you have the gene, PTC will be detectable to you. Sprouts and cabbages are laced with PTC. 

I love the story of the sensitivity’s discovery. There were two scientists working in a lab, one was decanting phenylthiocarbamide, and had no idea the other could smell the horrific stench. Intrigued he basically gassed family members until he had a working hypothesis and went from there. While he didn’t have the ability to inspect the genes, it was clearly genetic in nature even in the 1930s.
