Epidermolysis bullosa simplex (EBS) is a disorder resulting from mutations in the genes encoding keratin 5 or keratin 14.[1]:598

Blister formation of EBS occurs at the dermoepidermal junction. Sometimes EBS is called epidermolytic.[citation needed]

Classification

Epidermolysis bullosa simplex may be divided into multiple types:

TypeLocus & GeneOMIM
Epidermolysis bullosa simplex with migratory circinate erythema12q13 (KRT5)609352
Epidermolysis bullosa simplex with mottled pigmentation.
Associated with a recurrent mutation in KRT14.[2]:557[3][4]
12q13 (KRT5)131960
Epidermolysis bullosa simplex, autosomal recessive17q12-q21 (KRT14)601001
Generalized epidermolysis bullosa simplex
Also known as "Koebner variant of generalized epidermolysis bullosa simplex", presents at birth to early infancy with a predilection for the hands, feet, and extremities, and palmar-plantar hyperkeratosis and erosions may be present.[1]:598[2]:556
17q12-q21 (KRT5), 12q13 (KRT14)131900
Localized epidermolysis bullosa simplex
Also known as "Weber–Cockayne syndrome,"[4]:460 and "Weber–Cockayne variant of generalized epidermolysis bullosa simplex", is characterized by onset in childhood or later in life, and is the most common variant of epidermolysis bullosa simplex.[1]:598[2]:557
17q12-q21 (KRT5), 17q11-qter, 12q13 (KRT14)131800
Epidermolysis bullosa herpetiformis
Also known as "Dowling-Meara epidermolysis bullosa simplex", presents at birth with a generalized distribution, often with oral mucosa involvement and variable lesions in infancy.[1]:598[2]:557
17q12-q21 (KRT5), 12q13 (KRT14)131760
Epidermolysis bullosa simplex with muscular dystrophy
A rare clinical entity, and is the only epidermolytic epidermolysis bullosa described that is not caused by a keratin mutation, presenting as a generalized intraepidermal blistering similar to the Koebner variant of generalized epidermolysis bullosa simplex, but also associated with adult onset muscular dystrophy.[1]:598[2]:557[4]
8q24 (PLEC1)226670
Epidermolysis bullosa simplex with pyloric atresia8q24 (PLEC1)612138
Epidermolysis bullosa simplex of Ogna
Has onset in infancy, presenting with seasonal blistering on acral areas during summer months.[1]:598[2]:557[4]
8q24 (PLEC1)131950
