Is Barth syndrome mitochondrial disease?
Objectives: Barth syndrome is an ultra-rare, infantile-onset, X-linked recessive mitochondrial disorder, primarily affecting males, due to variants in TAZ encoding for the cardiolipin transacylase tafazzin.
How is the mitochondria affected by Barth syndrome?
Barth syndrome lymphoblasts have impaired mitochondrial functions. The lack of mature cardiolipin led to changes in electron transport chain stability. A compensatory increase in mitochondrial content prevents a decrease ATP synthesis.
Can Barth syndrome be cured?
There is no cure or specific treatment for Barth syndrome. Treatment focuses on reducing symptoms and preventing complications. These treatments may include: physical therapy to help babies with reduced muscle tone.
What does Barth syndrome do to the body?
People with Barth syndrome have a low level of white blood cells (neutropenia). The white blood cells in our body help us fight infections. Due to neutropenia, people have mouth ulcers, pneumonia or blood infections. Males with Barth syndrome have weak muscles (hypotonia) especially in the hands and feet.
What is the cause of Barth syndrome?
Barth syndrome (BTHS) is a rare, genetic disorder of lipid metabolism that primarily affects males. It is caused by a mutation in the tafazzin gene (TAZ, also called G4. 5) which leads to decreased production of an enzyme required to produce cardiolipin.
Can Bloom syndrome be prevented?
There is no cure for Bloom syndrome. Children with Bloom syndrome need nutritional monitoring to ensure maximum growth. People with the disease are advised to stay out of the sun and wear sunscreen to prevent skin lesions, particularly during childhood.
What is the genetic cause of Barth syndrome?
Barth syndrome (BTHS) is a rare, genetic disorder of lipid metabolism that primarily affects males. It is caused by a mutation in the tafazzin gene (TAZ, also called G4.5) which leads to decreased production of an enzyme required to produce cardiolipin.
Where is the TAZ gene located in Barth syndrome?
We want to hear from you. Barth syndrome is caused by mutations in the TAZ gene, which is located on the X chromosome . The TAZ gene provides “instructions” for a group of proteins called tafazzins that serve at least two functions.
How is Barth syndrome related to lipid metabolism?
Barth syndrome (BTHS) is a rare, genetic disorder of lipid metabolism that primarily affects males. It is caused by a mutation in the tafazzin gene (TAZ, also called G4.5) which leads to decreased production of an enzyme required to produce cardiolipin. Cardiolipin is an essential lipid that is important in energy…
What happens to a boy with Barth syndrome?
Early and accurate diagnosis is key to prolonged survival for boys born with Barth syndrome. The disorder was once considered uniformly fatal in infancy, but some individuals are now living much longer. Severe infections and cardiac failure are common causes of death in affected children.

What are the symptoms of Barth syndrome in males?
General Discussion. Barth syndrome is a genetic condition that mainly affects males. Some of the symptoms of the condition include enlarged heart, low blood cell count, weakness of muscles, and fatigue. Additionally, there can be increased levels of chemicals like 3-methyglutaconic acid and 2-ethyl hydracrylic acid in the urine or blood.
