Cystic fibrosis is a genetic disorder that affects the lungs, digestive system, and other organs. It is not a metabolic disease.

Phenylketonuria is a genetic disorder that affects the body's ability to break down the amino acid phenylalanine. It is the most common childhood metabolic disease.

The treatment for phenylketonuria is a low-phenylalanine diet. This diet restricts the intake of foods that contain phenylalanine.

Type 1 Gaucher disease is the most common type. It is characterized by an accumulation of Gaucher cells in the spleen, liver, and bone marrow.

The treatment for Gaucher disease is enzyme replacement therapy. This therapy replaces the missing enzyme that is needed to break down Gaucher cells.

Type A Niemann-Pick disease is the most common type. It is characterized by an accumulation of sphingomyelin in the spleen, liver, and brain.

The treatment for Niemann-Pick disease is bone marrow transplantation. This procedure replaces the diseased bone marrow with healthy bone marrow.

Classic maple syrup urine disease is the most common type. It is characterized by a severe accumulation of branched-chain amino acids in the blood and urine.

The treatment for maple syrup urine disease is a low-protein diet. This diet restricts the intake of foods that contain protein.

Mitochondrial diseases can cause a variety of symptoms, including muscle weakness, fatigue, seizures, and other neurological problems.

There is currently no cure for mitochondrial disease. Treatment focuses on managing the symptoms and improving the quality of life.

All of the above are risk factors for childhood metabolic disease.

Early diagnosis of childhood metabolic disease is important to prevent complications, start treatment early, and improve the quality of life.

Newborn screening, blood tests, and urine tests are all screening tests for childhood metabolic disease.

Genetic testing can be used to confirm the diagnosis of childhood metabolic disease, identify the specific genetic mutation, and determine the inheritance pattern.
