The Human Phenotype Ontology (HPO) provides the following list of features that have been reported in people with this condition. Much of the information in the HPO comes from Orphanet, a European rare disease database. If available, the list includes a rough estimate of how common a feature is (its frequency). Frequencies are based on a specific study and may not be representative of all studies. You can use the MedlinePlus Medical Dictionary for definitions of the terms below.

Epidermolysis bullosa simplex (EBS) is usually inherited in an autosomal dominant pattern, which means one copy of the altered (mutated) gene in each cell is sufficient to cause the condition. The mutated gene may be inherited from an affected parent, or it may occur for the first time in the affected individual.[4][5] When an individual affected with an autosomal dominant condition has children, each child has a 50% (1 in 2) chance to inherit the mutated gene and be affected.
In rare cases, EBS is inherited in an autosomal recessive pattern. Autosomal recessive inheritance means the condition results when both copies of the gene in each cell have a mutation (one copy inherited from each parent). The parents of an individual with an autosomal recessive condition typically each carry one copy of the mutated gene and are referred to as carriers. Carriers are typically unaffected and do not have signs or symptoms of the condition.[4] When two carriers for an autosomal recessive condition have children, each child has a 25% (1 in 4) risk to have the condition, a 50% (1 in 2) risk to be a carrier, and a 25% risk to not have the condition and not be a carrier.
Affected individuals or family members who are unsure of the inheritance pattern of EBS in their family and are interested in learning more about this should consult with a genetics professional.
Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.
Nonprofit support and advocacy groups bring together patients, families, medical professionals, and researchers. These groups often raise awareness, provide support, and develop patient-centered information. Many are the driving force behind research for better treatments and possible cures. They can direct people to research, resources, and services. Many groups also have experts who serve as medical advisors. Visit their website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.
Living with a genetic or rare disease can impact the daily lives of patients and families. These resources can help families navigate various aspects of living with a rare disease.
These resources provide more information about this condition or associated symptoms. The in-depth resources contain medical and scientific language that may be hard to understand. You may want to review these resources with a medical professional.
Gordon Research Conference – Intermediate Filaments
Saturday, June 14, 2014 -
Friday, June 20, 2014
Location: Mount Snow Resort,
West Dover,
VT
Description:
The 2014 GRC-Intermediate Filaments will include short talks, discussions, and poster presentations from the leaders in the field. It will provides several functional perspectives with an emphasis on the paradigm shifting notion that IFs are not only structural proteins but also play essential roles as signaling organizers and buffers of cellular stress, which contribute to number of disease pathologies. There will be robust discussions on how mutations in the IF genes encoding these IF proteins are responsible for rare diseases, such as epidermolysis bullosa simplex (EBS), but extending into the entire list of rare diseases outlined above. Discussions will be focused on how cell biology and physiology efforts are providing unique therapeutic approaches to the highly complex disorders, such as those caused by lamin A/C gene mutations, which are involved in Progeria.

Is it possible for me to have a child? I believe I can get pregnant but with the skin condition and everything I didn't know if I could carry the child or give birth. Also, what are the chances that my child would inherit what I have? See answer
My 1.5 year old daughter has epidermolysis bullosa simplex with mottled pigmentation. Is this disease curable? What treatment is available, and how might I find out if specific treatments may be available where I live? See answer
