Disease Profile
Epidermolysis bullosa acquisita
Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Inheritance
Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease.
Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype.
X-linked
dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.
dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.
X-linked
recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.
recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.
Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.
Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Summary
Epidermolysis bullosa acquisita (EBA) is a rare autoimmune disorder that causes the skin to blister in response to minor injury. Common areas of blistering include the hands, feet, knees, elbows, and buttocks. It can also affect the mouth, nose, and eyes. Some affected people have other health problems such as Crohn's disease, systemic lupus erythematosus, amyloidosis, or multiple myeloma. EBA is not
Symptoms
Non-inflammatory or mildly inflammatory EBA affecting only trauma-prone skin (the "classic" form) may cause:
- tense, bloodor pus-filled blisters, mostly on the hands, knees, knuckles, elbows and ankles
- mucous-membrane blisters that rupture easily
- healing with significant scarring and small white spots (milia)
Generalized inflammatory EBA may cause:
- widespread blisters that are not localized to trauma-prone sites
- generalized redness and itching
- healing with minimal scarring
- blisters on various mucous membranes
- significant scarring and dysfunction[1]
The features of the condition may change during the course of the disease or may represent two forms at the same time.[2]
This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.
