PKU (phenylketonuria) is a disorder in which the affected individual cannot break down the amino acid phenylalanine. This leads to a buildup of phenylalanine in the body, which can cause intellectual disability unless the individual adheres to a special diet low in phenylalanine. Hemophilia is a bleeding disorder, sickle-cell disease is a blood disorder, and Tay-Sachs disease is a neurological disorder, none of which are associated with intellectual disability caused by diet.
