" /> Peeling skin syndrome 1 - CISMeF





Preferred Label : Peeling skin syndrome 1;

Symbol : PSS1;

CISMeF acronym : PSS; PSS1;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : PSS; Keratolysis exfoliativa congenita; Skin peeling, familial continuous generalized; Deciduous skin;

Description : Two main subtypes of peeling skin syndrome, noninflammatory type A and inflammatory type B, have been suggested (Traupe, 1989; Judge et al., 2004). Type B, in which generalized peeling skin is associated with pruritus and atopy, is an unusual autosomal recessive ichthyosiform erythroderma characterized by lifelong patchy peeling of the entire skin with onset at birth or shortly thereafter. Several patients have been reported with high IgE levels (summary by Oji et al., 2010). - Heterogeneity The noninflammatory 'type A' form of peeling skin syndrome, the so-called acral type in which skin peeling is limited to the dorsa of the hands and feet (609796), is caused by mutation in the TGM5 gene (603805).;

Inheritance : Autosomal recessive;

Molecular basis : Caused by mutation in the corneodesmosin gene (CDSN, 602593.0003);

Laboratory abnormalities : Low plasma tryptophan (inflammatory type B);

Prefixed ID : #270300;
