| pubmed-article:1284546 | pubmed:abstractText | We investigated the molecular genetics of epidermolytic hyperkeratosis (EHK), a dominant disorder characterized by epidermal blistering, hyperkeratosis, vacuolar degeneration and clumping of keratin filaments. Based on this pathology, we have excluded by linkage analysis several candidate genes for the disease; in contrast, complete linkage was obtained with the type II keratin, K1, on 12q11-q13. Linkage in this region of chromosome 12 was confirmed using several other markers, and multi-locus linkage analyses further supported this location. Keratins are excellent EHK gene candidates since their expression is specific to the suprabasal epidermal layers. In the pedigree studied here, a type II keratin gene, very probably K1, is implicated as the site of the molecular defect causing EHK. | lld:pubmed |
