To predict: The treatment strategies for phenylketonuria (PKU). Introduction: Phenylketonuria is a recessive disorder that mainly affects the Caucasian and the Asians. The diseases are marked by increased levels of phenylalanine in the blood which can result in intellectual disability and other physiological 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 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 predict: The treatment strategies for phenylketonuria (PKU).

Introduction: Phenylketonuria is a recessive disorder that mainly affects the Caucasian and the Asians. The diseases are marked by increased levels of phenylalanine in the blood which can result in intellectual disability and other physiological 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 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.

The following figure is from Caterina et al. The capsaicin receptor: a heat activated ion channel in the pain pathway. Nature, 1997. Black boxes indicate capsaicin, white circles indicate resinferatoxin. You are a chef in a fancy new science-themed restaurant. You have a recipe that calls for 1 teaspoon of resinferatoxin, but you feel uncomfortable serving foods with "toxins" in them. How much capsaicin could you substitute instead?
