Other forms | ||
Loricrin keratoderma | Autosomal dominant | LOR |
Erythrokeratodermia variabilis¥ | GJB3/GJB4 | |
Peeling skin syndrome | Autosomal recessive | TGM5, CSTA, CHST8, SERPINB8, FLG2, CDSN |
Congenital reticular ichthyosiform erythroderma | Autosomal dominant (?) (isolated cases) | Locus unknown |
Keratosis linearis-ichthyosis congenita-keratoderma | Autosomal recessive | POMP |
* Often delayed onset (in recessive X-linked ichthyosis, mild scaling and erythroderma may be present already at birth).
¶ Few cases of autosomal dominant lamellar ichthyosis described in literature (locus unknown).
Δ Also known as ICHTHYIN gene.
◊ KRT1 mutations are often associated with palmoplantar involvement.
§ May indicate gonadal mosaicism, which can cause generalized epidermolytic ichthyosis in offspring generation.
¥ Whether progressive symmetric erythrokeratodermia represents distinct Mendelian disorders of cornification form is debated.Do you want to add Medilib to your home screen?
