Dystrophic epidermolysis bullosa

What it is

A group of inherited epidermolysis bullosa (EB) characterized by cutaneous and mucosal fragility resulting in blisters and superficial ulcerations that develop below the lamina densa of the cutaneous basement membrane and that heal with significant scarring and milia formation. Dystrophic epidermolysis bullosa (DEB) comprises four major and several rare sub-types with the three most common being intermediate dominant DEB, severe recessive DEB and intermediate recessive DEB.

Classified as

Clinical group

Prevalence figures describe populations, not individuals, and are often estimates from a single study. Where the figure is an incidence or a birth prevalence, it says so.

Genes reported in subtypes

Orphanet records these genes on 6 more specific entries under this disorder, not on this entry itself:

A well-studied disease is usually split into subtypes, and the gene is curated on whichever one the evidence belongs to. Open a subtype to see which gene goes with it.

ICD-10 codes

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
