Disease Associations Ichthyosis, congenital, autosomal recessive 1 (ARCI1) [MIM:242300]: A form of autosomal recessive congenital ichthyosis, a disorder of keratinization with abnormal differentiation and desquamation of the epidermis, resulting in abnormal skin scaling over the whole body. The main skin phenotypes are lamellar ichthyosis (LI) and non-bullous congenital ichthyosiform erythroderma (NCIE), although phenotypic overlap within the same patient or among patients from the same family can occur. Lamellar ichthyosis is a condition often associated with an embedment in a collodion-like membrane at birth; skin scales later develop, covering the entire body surface. Non-bullous congenital ichthyosiform erythroderma characterized by fine whitish scaling on an erythrodermal background; larger brownish scales are present on the buttocks, neck and legs. {ECO:0000269PubMed:11251583, ECO:0000269PubMed:11511296, ECO:0000269PubMed:19890349, ECO:0000269PubMed:7773290, ECO:0000269PubMed:7824952, ECO:0000269PubMed:9326318}. Note=The disease is caused by mutations affecting the gene represented in this entry.
