Bart syndrome is a rare genetic disorder characterized by the combination of congenital localized absence of skin, and mucosal membrane abnormalities. It is named after the British dermatologist R.J. Bart who first described the condition in 1966.
Symptoms and Signs[edit]
The primary symptom of Bart syndrome is the presence of blistering on the skin, particularly on the hands and feet. These blisters can be present at birth or develop shortly thereafter. Other symptoms can include nail dystrophy, mucosal inflammation, and anemia.
Causes[edit]
Bart syndrome is caused by mutations in the COL7A1 gene. This gene provides instructions for making a protein that is used to assemble larger molecules called type VII collagen fibers. These fibers play a crucial role in anchoring the top layer of skin, the epidermis, to underlying layers. Mutations in the COL7A1 gene interfere with the assembly of type VII collagen fibers, which weakens the connection between skin layers and leads to the blistering seen in Bart syndrome.
Diagnosis[edit]
Diagnosis of Bart syndrome is based on the clinical features, including the presence of skin blisters and other symptoms. Genetic testing can confirm the diagnosis by identifying a mutation in the COL7A1 gene.
Treatment[edit]
There is currently no cure for Bart syndrome. Treatment is focused on managing the symptoms and preventing complications. This can include wound care for the skin blisters, and treatment for anemia if it is present.
Prognosis[edit]
The prognosis for individuals with Bart syndrome varies. Some individuals may have a relatively mild form of the disease with few complications, while others may experience severe symptoms and complications.
