• \Rough skin (finding)\Ichthyosis hystrix (disorder)\A rare type of keratinopathic ichthyosis characterised by the presence of severe hyperkeratotic lesions and palmoplantar keratoderma. The skin is usually normal at birth. The disease starts in early childhood with severe hyperkeratosis of yellow-brown or grey colour, and of spiky, cobblestone-like (hystrix) or verrucous appearance. Contrary to other keratinopathic ichthyoses, no skin fragility/blister formation or erythroderma is present. The disease results from heterozygous frameshift mutation in a section of the KRT1 gene encoding keratin 1 (K1). These mutations lead to an abnormal supramolecular organisation of keratin intermediate filaments and may be related to defects in cytoplasmic trafficking and integrity of cellular structures such as organelles and nucleus. Transmission is autosomal dominant but some sporadic cases have been reported.

The skin is usually normal at birth. The disease starts in early childhood with severe hyperkeratosis of yellow-brown or grey colour, and of spiky, cobblestone-like (hystrix) or verrucous appearance. Contrary to other keratinopathic ichthyoses, no skin fragility/blister formation or erythroderma is present. The disease results from heterozygous frameshift mutation in a section of the KRT1 gene encoding keratin 1 (K1). These mutations lead to an abnormal supramolecular organisation of keratin intermediate filaments and may be related to defects in cytoplasmic trafficking and integrity of cellular structures such as organelles and nucleus. Transmission is autosomal dominant but some sporadic cases have been reported.
