Phenylketonuria (PKU) is a genetic disorder that prevents people from processing an amino acid called phenylalanine. People with PKU can not break down that amino acid. This means they have a hard time making proteins important for brain function and for making melanin (protein that gives color to our skin, hair and eyes).
Use the information above to describe 2 symptoms or difficulties people with Phenylketonuria (PKU) might experience. Provide reasoning for your responses.
