What is PKU?

Phenylketonuria (PKU) is a rare inherited genetic disorder that affects the way the body processes the amino acid phenylalanine, which is found in protein-rich foods. In India, the condition is a key focus of newborn screening programmes, especially in states like Tamil Nadu, Karnataka, and Kerala, where state-run initiatives test for PKU alongside other congenital disorders. If left undiagnosed and untreated, phenylalanine accumulates to toxic levels in the blood, causing irreversible intellectual disability, seizures, and developmental delays. Treatment involves a strict lifelong low-phenylalanine diet, special medical formulas, and regular monitoring to maintain safe blood levels. PKU is caused by mutations in the PAH gene, which disrupts the production of the enzyme phenylalanine hydroxylase. In the Indian context, awareness and access to dietary management products remain uneven, though the Rashtriya Bal Swasthya Karyakram (RBSK) includes PKU under its list of identifiable conditions at birth. Medical exams such as NEET PG and AIIMS often include PKU in questions related to inborn errors of metabolism, making it an important topic for aspirants. Early detection through heel-prick testing within 48–72 hours of birth is critical for preventing neurological damage, and affected individuals who adhere to dietary restrictions can lead normal lives.
