Phenylketonuria is an inherited genetic disorder. It is caused by mutations in the PAH gene, which can result in inefficient or nonfunctional phenylalanine hydroxylase, an enzyme responsible for the metabolism of excess phenylalanine. This results in the buildup of dietary phenylalanine to potentially toxic levels.
Newborn screening (NBS) is a public health program of screening in infants shortly after birth for conditions that are treatable, but not clinically evident in the newborn period. The goal is to identify infants at risk for these conditions early enough to confirm the diagnosis and provide intervention that will alter the clinical course of the ...
Hyperphenylalaninemia is a medical condition characterized by mildly or strongly elevated concentrations of the amino acid phenylalanine in the blood. Phenylketonuria (PKU) can result in severe hyperphenylalaninemia. [2] Phenylalanine concentrations are routinely screened in newborns by the neonatal heel prick (Guthrie test), which takes a few ...
The European Society for Phenylketonuria and Allied Disorders Treated as Phenylketonuria ( E.S.PKU) is a Europe-based non-profit organization. It was founded in 1987 by patient-driven associations to help improve the treatment of phenylketonuria (PKU) in Europe.
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. Medications
Treatment of HFI depends on the stage of the disease, and the severity of the symptoms. Stable patients without acute intoxication events are treated by careful dietary planning that avoids fructose and its metabolic precursors. Fructose is replaced in the diet by glucose, maltose or other sugars.
Failure to thrive. Failure to thrive (FTT), also known as weight faltering or faltering growth, indicates insufficient weight gain or absence of appropriate physical growth in children. [2][3] FTT is usually defined in terms of weight, and can be evaluated either by a low weight for the child's age, or by a low rate of increase in the weight.
Fatty-acid metabolism disorders result when both parents of the diagnosed subject are carriers of a defective gene. This is known as an autosomal recessive disorder. Two parts of a recessive gene are required to activate the disease. If only one part of the gene is present then the individual is only a carrier and shows no symptoms of the disease.
