Keratinocyte differentiation is essential for skin development and the formation of the skin permeability barrier. This process involves an orchestrated remodeling of lipids. The cleavage of precursor lipids from lamellar bodies by β-glucocerebrosidase, sphingomyelinase, phospholipases and sterol sulfatase generates ceramides, non-esterified fatty acids and cholesterol for the lipid-containing ...
Harlequin ichthyosis (HI), which is the most severe genodermatosis, is caused by loss-of-function mutations in ABCA12, a member of the ATP-binding cassette transporter family. To investigate the pathomechanism of HI and the function of the ABCA12 protein, we generated ABCA12-deficient mice (Abca12(-/-)) by targeting Abca12. Abca12(-/-) mice closely reproduce the human HI phenotype, showing mark...
M ost statistics on the incidence of hereditary ichthyosis are acknowledged as best-guess estimates. The exceptions are population-based studies for the prevalence of steroid sulfatase deficiency (xlinked ichthyosis) and mutations in filaggrin (ichthyosis vulgaris). We wondered whether the unique International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) code for...
harlequin ichthyosis is a rare and the most severe form of congenital ichthyosis. although prenatal diagnosis is difficult for this disorder, recently, this obstacle has markedly improved with the use of dna-based prenatal diagnosis. here in, we presented a neonate with harlequin ichthyosis born by assisted reproductive technology (art). in this case, the diagnosis of harlequin ichthyosis was n...
We report the genomic localization by homozygosity mapping and the identification of a gene for a new form of non-syndromic autosomal recessive congenital ichthyosis. The phenotype usually presents as non-bullous congenital ichthyosiform erythroderma with fine whitish scaling on an erythrodermal background; larger brownish scales are present on the buttocks, neck and legs. A few patients presen...
Harlequin Ichthyosis is a severe skin disease caused by mutations in the human gene encoding ABCA12. Here, we characterize a novel mutation in intron 29 of the mouse Abca12 gene that leads to the loss of a 5' splice donor site and truncation of the Abca12 RNA transcript. Homozygous mutants of this smooth skin or smsk allele die perinatally with shiny translucent skin, typical of animal models o...
