Desmoplakin mutations with palmoplantar keratoderma, woolly hair and cardiomyopathy.
Mutations in genes encoding for desmosomal components are associated with a broad spectrum of phenotypes comprising skin and hair abnormalities and account for 45-50% of cases of arrhythmogenic right ventricular cardiomyopathy. Today, more than 120 dominant and recessive desmoplakin (DSP) gene mutations have been reported to be associated with skin, hair and/or heart defects. Here we report on ...
متن کاملGene for arrhythmogenic right ventricular cardiomyopathy with diffuse nonepidermolytic palmoplantar keratoderma and woolly hair (Naxos disease) maps to 17q21.
BACKGROUND Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a heart muscle disease of unknown etiology that causes arrhythmias, heart failure, and sudden death. Diagnosis can be difficult, and this hampers investigation of its molecular basis. Forms of ARVC in which gene penetrance and disease expression are greater should facilitate genetic study. We undertook a clinical and genetic i...
متن کاملHaploinsufficiency of desmoplakin causes a striate subtype of palmoplantar keratoderma.
Desmosomes are highly organized intercellular adhesive junctions that are particularly prominent in epidermis and other tissues experiencing mechanical stress. Desmoplakin, a constitutive component of the desmosomal plaque, is the most abundant protein present in such junctions and plays a critical role in linking the intermediate filament network to the plasma membrane in these tissues. Here w...
متن کاملPIGO deficiency: palmoplantar keratoderma and novel mutations
BACKGROUND Several genetic defects have been identified in the glycosylphosphatidylinositol (GPI) anchor synthesis, including mutations in PIGO encoding phosphatidylinositol glycan anchor biosynthesis class O protein. These defects constitute a subgroup of the congenital disorders of glycosylation (CDG). Seven patients from five families have been reported carrying variants in PIGO that cause a...
متن کاملBrunauer-Fuhs-Siemens palmoplantar keratoderma: A rare, striate type of focal palmoplantar keratoderma
Brunauer-Fuhs-Siemens palmoplantar keratoderma, commonly known as striate palmoplantar keratoderma, is a rare, autosomally inherited disease of linear hyperkeratosis in which patient usually presents with conspicuous longitudinal hyperkeratosis on volar surface of hands and feet. Mutations in 3 genes namely desmoglein 1, desmoplakin and keratin 1, have been identified and held responsible for t...
