The foods that contain phenylalanine. Introduction: The disease phenylketonuria (PKU) is an autosomal recessive disorder. This is a genetic disorder that results in the alteration in the gene encoding for phenylalanine hydroxylase that leads to phenylalanine build up in the body causing intellectual disability, seizures, delayed disability, hyperactivity and psychiatric problems. The case study describes a couple who have given birth to a second child and are informed about their newborn daughter’s genetic screening tests. The genetic tests indicated abnormally high levels of amino acid phenylalanine in the blood. Phenylketonuria (PKU) also known as hyperphenylalaninemia. This disease occurs 1 in every 10,000 births. The classic form of PKU constitutes to 2/3 rd of the cases. It is an autosomal recessive disorder implying that both the alleles of the patient are affected. When untreated it can lead to intellectual disability, seizures, and hyperactivity. The EEG shows abnormality along with the prominent mousy odor of skin, hair, and urine.

Summary Introduction

To determine: The effect of disruptive diet therapy on the everyday life of the newborn suffering from PKU.

Introduction: Phenylketonuria is characterized by the presence of high levels of amino acid phenylalanine in the blood. The affected individual lacks the enzyme phenylalanine hydroxylase that causes the metabolism of the amino acid which results in the build-up of phenylalanine in the blood.
