Phenylketonuria (PKU) is a genetic disorder that affects how the body processes the amino acid phenylalanine. By controlling dietary intake of phenylalanine, individuals with PKU can manage the effects of their condition, illustrating the dynamic interaction between heredity (the genetic disorder) and the environment (dietary intake).
