TAS2R38 es un receptor de gusto amargo^[1]^[2] que facilita la percepción del sabor de la feniltiocarbamida (PTC, por su sigla en inglés)^[3] y propiltiouracilo (PROP),^[4] aunque no explica a los supertasters.^[5] Los portadores del alelo PAV experiencian más amargura en los vegetales^[6] y los consumen menos frecuentemente y en menor cantidad.^[7]
