How Do You Spell CLASSICAL PHENYLKETONURIAS?

1. Classical phenylketonurias (PKU) is a term used to describe a group of inherited metabolic disorders that affect the body's ability to break down an amino acid called phenylalanine. This condition is caused by a deficiency or absence of an enzyme called phenylalanine hydroxylase (PAH).

   Phenylalanine is obtained through the diet from certain protein-containing foods, and normally, the enzyme PAH converts phenylalanine into another amino acid called tyrosine. However, in classical PKU, the lack of PAH activity leads to the accumulation of phenylalanine in the blood and body tissues, which can lead to various neurological and developmental problems.

   The symptoms of classical PKU typically become apparent within a few months after birth. Without treatment, affected individuals may develop intellectual disability, developmental delay, seizures, behavioral issues, and issues with executive functioning. However, when diagnosed early and treated with a controlled diet low in phenylalanine, individuals with classical PKU can lead normal lives and prevent or minimize the associated complications.

   Genetic mutations in the PAH gene are responsible for classical PKU, and the condition follows an autosomal recessive inheritance pattern, meaning that both copies of the gene must be affected to develop the condition.

   Overall, classical phenylketonurias is a group of genetic disorders characterized by the inability to properly metabolize phenylalanine due to a deficiency or absence of the enzyme phenylalanine hydroxylase. Early diagnosis and a lifelong restricted diet can help individuals with this condition lead normal lives and prevent cognitive and neurological complications.
