Mutations in the transporter ABCA12 are associated with lamellar ichthyosis type 2.
Lamellar ichthyosis type 2 (LI2) is a rare autosomal recessive skin disorder for which a gene has been localized on chromosome 2q33-35. We report the identification of five missense mutations in the ABCA12 gene in nine families from Africa affected by LI2. The mutations were homozygous in eight consanguineous families and heterozygous in one non-consanguineous family. Four of these mutations ar...
متن کاملMutations in lipid transporter ABCA12 in harlequin ichthyosis and functional recovery by corrective gene transfer.
Harlequin ichthyosis (HI) is a devastating skin disorder with an unknown underlying cause. Abnormal keratinocyte lamellar granules (LGs) are a hallmark of HI skin. ABCA12 is a member of the ATP-binding cassette transporter family, and members of the ABCA subfamily are known to have closely related functions as lipid transporters. ABCA3 is involved in lipid secretion via LGs from alveolar type I...
متن کاملTransglutaminase-1 Mutations in Omani Families with Lamellar Ichthyosis
OBJECTIVE To determine the molecular basis of familial ichthyosis in three Omani families. SUBJECTS AND METHODS Nine patients from three consanguineous families, A, B, and C, were born with typical features of lamellar ichthyosis subtype including collodion membrane and maintained ectropion, and epidermal scaling through their childhood. The 4 patients from family B had more severe symptoms r...
متن کاملLamellar Ichthyosis with Rickets
Lamellar ichthyosis (LI) is a rare genetic disorder with autosomal recessive inheritance. It is equally seen in both sexes and usually manifests at birth. The child presents as a collodion baby. The erythema is minimal or absent; but when present, it is maximum on the face. The scaling is generalized, accentuated on lower extremities and flexural areas. Rickets is a condition in which there is ...
متن کاملThe roles of ABCA12 in keratinocyte differentiation and lipid barrier formation in the epidermis
ABCA12 is a member of the large superfamily of ATP-binding cassette (ABC) transporters, which bind and hydrolyze ATP to transport various molecules across limiting membranes or into vesicles. The ABCA subfamily members are thought to be lipid transporters. ABCA12 is a keratinocyte transmembrane lipid transporter protein associated with the transport of lipids in lamellar granules to the apical ...
