Ontology: Hyperkeratosis, Epidermolytic (C0079153)

Definition (NCI) An autosomal dominant inherited skin disorder caused by mutations in the KRT1 and KRT10 genes. It is manifested at birth and is characterized by generalized erythema, skin blisters and skin fragility.
Definition (MSH) A form of congenital ichthyosis inherited as an autosomal dominant trait and characterized by ERYTHRODERMA and severe hyperkeratosis. It is manifested at birth by blisters followed by the appearance of thickened, horny, verruciform scales over the entire body, but accentuated in flexural areas. Mutations in the genes that encode KERATIN-1 and KERATIN-10 have been associated with this disorder.

Ontology: Congenital Nonbullous Ichthyosiform Erythroderma (C0079154)

Definition (NCI) A very rare, autosomal recessive inherited skin disorder present at birth. It is characterized by the presence of a transparent membrane encasing the newborn. This membrane sheds in about two weeks after birth to reveal generalized scaling and skin erythema.
Definition (MSH) A chronic, congenital ichthyosis inherited as an autosomal recessive trait. Infants are usually born encased in a collodion membrane which sheds within a few weeks. Scaling is generalized and marked with grayish-brown quadrilateral scales, adherent at their centers and free at the edges. In some cases, scales are so thick that they resemble armored plate.
