Phenylketonuria is inherited in an autosomal recessive fashion. PKU is an autosomal recessive metabolic genetic disorder. As an autosomal recessive disorder, two PKU alleles are required for an individual to experience symptoms of the disease. For a child to inherit PKU, both parents must have and pass on the defective gene. [17]
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 ...
E.g., reduction of dietary protein remains a mainstay of treatment for phenylketonuria and other amino acid disorders; Dietary supplementation or replacement E.g., oral ingestion of cornstarch several times a day helps prevent people with glycogen storage diseases from becoming seriously hypoglycemic.

It shares history with PKU and hyperphenylalaninemia (HPA) . Asbjørn Følling, a physician studying metabolic diseases, identified an excess of phenylpyruvate as the cause of a strange, musty odor from the urine of two Norwegian children. [13] Further research by Penrose in 1935 lead to the coining of the term, "phenylketonuria". The ...

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 phenylalanine hydroxylase, which converts the amino acid phenylalanine to ...
