- It is inherited in an autosomal recessive pattern and has an incidence of 1 in 10,000 births.
- PKU causes an accumulation of phenylalanine and its metabolites in the body, which can lead to various clinical and biochemical manifestations.
- Symptoms of untreated PKU can include neurological problems, skin rashes, lighter skin and hair color, small head size, hyperactivity, intellectual disability, delayed development, and mental health disorders.
- PKU is mostly detected by screening newborns for increased plasma levels of phenylalanine.
- Diagnosis can also be confirmed by detecting phenyl pyruvate in urine.
- Treatment for PKU is lifelong and may include a special low-phenylalanine diet, medication, or supplements.
