Phenylketonuria

Phenylketonuria (PKU)

Overview

Type of disease: Rare conditions

Phenylketonuria (PKU) is an inherited condition that is caused by toxic levels of phenylalanine in the body. If left untreated, this buildup of phenylalanine can cause severe intellectual disabilities.  Because PKU can be detected by a simple blood test and is treatable, newborn screening is available for this disorder.
