Does PKU require a special diet?
Does PKU require a special diet?
Diet. The main treatment for PKU is a low-protein diet that completely avoids high-protein foods (such as meat, eggs and dairy products) and controls the intake of many other foods, such as potatoes and cereals.
What should individuals with PKU avoid?
Children and adults with PKU should eat a low-protein diet. They should avoid high-protein foods, like milk, dairy, meats, eggs, nuts, soy, and beans. A person with PKU also should avoid the artificial sweetener aspartame, which contains phenylalanine.
What is the genetic and biochemical basis for PKU?
Phenylketonuria (PKU) is an autosomal recessive inborn error of phenylalanine (Phe) metabolism resulting from deficiency of phenylalanine hydroxylase (PAH). Most forms of PKU and hyperphenylalaninaemia (HPA) are caused by mutations in the PAH gene on chromosome 12q23. 2.
What is the molecular basis of phenylketonuria?
Phenylketonuria (PKU) is an inborn error of metabolism that results from a deficiency of phenylalanine hydroxylase (PAH). We characterized the PAH mutations of 79 independent Korean patients with PKU or hyperphenylalaninemia.
What can I eat on a PKU diet?
The diet for PKU consists of a phenylalanine-free medical formula and carefully measured amounts of fruits, vegetables, bread, pasta, and cereals. Many people who follow a low phenylalanine (phe) food pattern eat special low protein breads and pastas.
What foods can a child with PKU eat?
What can you eat on a PKU diet?
What protein is affected by PKU?
Phenylketonuria (PKU) is a rare genetic condition that causes an amino acid called phenylalanine to build up in the body. Amino acids are the building blocks of protein. Phenylalanine is found in all proteins and some artificial sweeteners.
What can you eat if you have PKU?
Is phenylketonuria a chromosomal or gene disorder?
Classical PKU is an autosomal recessive disorder, caused by mutations in both alleles of the gene for phenylalanine hydroxylase (PAH), found on chromosome 12.
Is phenylketonuria a point mutation?
Point mutations in the PAH gene are known to cause PKU in various ethnic groups, and large deletions or duplications account for up to 3% of the PAH mutations in some ethnic groups.
What happens when someone with PKU eat protein?
A dangerous buildup of phenylalanine can develop when a person with PKU eats protein-rich foods, such as milk, cheese, nuts or meat, and even grains such as bread and pasta, or eats aspartame, an artificial sweetener. This buildup of phenylalanine results in damage to nerve cells in the brain.
