EtiopathogenesisThis section has been translated automatically.
Autosomal-dominant inheritance of mutations on the KRT 5 gene (HKRT5 gene also KRT5 gene) or KRT14 gene, which lead to missing or reduced expression of the proteins keratin 5 or keratin 14.
ManifestationThis section has been translated automatically.
Usually during the first 3 months of life or in the course of the 1st year of life.
LocalizationThis section has been translated automatically.
Mostly palmar, plantar, fingernails, perioral, trunk and neck.
Clinical featuresThis section has been translated automatically.
- herpetiform grouped, bulging, serous or haemorrhagic blisters or blisters that usually heal without scarring.
- milia or focal atrophy with hyper- or hypopigmentation
- rather discrete palmar or plantar hyperkeratoses
- Nail dystrophies in the form of nail thickening already occur in infancy. Also Anonychia.
- telogenic effluvium
- Blistering of the oral mucosa and larynx (hoarseness), danger of laryngeal stenosis
- Oesophageal involvement
- Dental anomalies
