Phenylketonuria leads to a build-up of phenylalanine, which can cause brain damage and lead to mental retardation and seizures if not properly managed. However, tyrosine is a non-essential amino acid that can be produced from phenylalanine, so a deficiency in tyrosine would not be a potential outcome of non-compliance with a phenylalanine-restricted diet. Eczema is also not typically associated with phenylketonuria. Phenylketonuria (PKU) is a genetic disorder in which the body cannot properly metabolize phenylalanine, an amino acid found in protein-containing foods. If PD's mom is not compliant with PD's PKU diet, he could potentially develop mental retardation and seizures due to the accumulation of phenylalanine in the brain. Eczema may also occur in some PKU patients due to a deficiency in essential fatty acids, but it is not a life-threatening complication. Tyrosine deficiency is not a direct result of non-compliance with a PKU diet, as tyrosine can be obtained through other dietary sources aside from phenylalanine.
