The blood of a two-week-old infant is collected for a PKU screening. A common example of pleiotropy is the human disease phenylketonuria (PKU). This disease causes mental retardation and reduced hair and skin pigmentation , and can be caused by any of a large number of mutations in the single gene on chromosome 12 that codes for the enzyme ...
Phenylketonuria (PKU)-like symptoms, including more pronounced developmental defects, skin irritation, and vomiting, may appear when phenylalanine levels are near 20 mg/dL (1200 mol/L). [1] Hyperphenylalaninemia is a recessive hereditary metabolic disorder that is caused by the body's failure to convert phenylalanine to tyrosine as a result of ...

Pegvaliase, sold under the brand name Palynziq, is a medication used for the treatment of the genetic disease phenylketonuria (PKU). [5] [9] [10] It is a phenylalanine (Phe)‑metabolizing enzyme. [5] Chemically, it is a pegylated derivative of the enzyme phenylalanine ammonia-lyase that metabolizes phenylalanine to reduce its blood levels. [5]
With the classical, or neonatal presentation of glycine encephalopathy, the infant is born after an unremarkable pregnancy, but presents with lethargy, hypotonia, apneic seizures and myoclonic jerks, which can progress to apnea requiring artificial ventilation, and often death. Apneic patients can regain spontaneous respiration in their second ...
