Summaries for ABCA12 Gene

Entrez Gene Summary for ABCA12 Gene

  • The membrane-associated protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intracellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, and White). This encoded protein is a member of the ABC1 subfamily, which is the only major ABC subfamily found exclusively in multicellular eukaryotes. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jul 2008]

GeneCards Summary for ABCA12 Gene

ABCA12 (ATP Binding Cassette Subfamily A Member 12) is a Protein Coding gene. Diseases associated with ABCA12 include Ichthyosis, Congenital, Autosomal Recessive 4B and Ichthyosis, Congenital, Autosomal Recessive 4A. Among its related pathways are CDK-mediated phosphorylation and removal of Cdc6 and Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds. Gene Ontology (GO) annotations related to this gene include signaling receptor binding and ATPase activity, coupled to transmembrane movement of substances. An important paralog of this gene is ABCA13.

  • Ichthyosis, congenital, autosomal recessive 4A (ARCI4A) [MIM:601277]: 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:0000269 PubMed:12915478, ECO:0000269 PubMed:17508018, ECO:0000269 PubMed:18284401, ECO:0000269 PubMed:19262603, ECO:0000269 PubMed:22257947}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Ichthyosis, congenital, autosomal recessive 4B (ARCI4B) [MIM:242500]: A rare, very severe form of congenital ichthyosis, in which the neonate is born with a thick covering of armor-like scales. The skin dries out to form hard diamond-shaped plaques separated by fissures, resembling armor plating. The normal facial features are severely affected, with distortion of the lips (eclabion), eyelids (ectropion), ears, and nostrils. Affected babies are often born prematurely and rarely survive the perinatal period. Babies who survive into infancy and beyond develop skin changes resembling severe non-bullous congenital ichthyosiform erythroderma. {ECO:0000269 PubMed:16675967, ECO:0000269 PubMed:16902423}. Note=The disease is caused by mutations affecting the gene represented in this entry.
