Mutations in the transporter ABCA12 are associated with lamellar ichthyosis type 2.

Abstract [show]
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 are localized in the first ATP-binding domain (nucleotide-binding fold), which is highly conserved in all ABC proteins. The ABCA12 protein belongs to a superfamily of membrane proteins that translocate a variety of substrates across extra- and intracellular membranes. ABCA transporters have been implicated in several autosomal recessive disorders, notably of lipid metabolism. By analogy with ABCA3, a lamellar body membrane protein in lung alveolar type II cells, ABCA12 could function in cellular lipid trafficking in keratinocytes.

75 All of the mutations were missense mutations and were found in the region of the protein encoded by exons 28-32: 4139A!G (N1380S) and 4142G!A (G1381E) in exon 28, 4541G!A (R1514H) in exon 30, 4615G!A (E1539K) in exon 31 and 4951G!A (G1651S) in exon 32. Login to comment
88 Four of the mutations (N1380S, G1381E, R1514H, E1539K) were situated in the first highly conserved ATP binding domain of the protein (Fig. 4). Login to comment
