Lamellar ichthyosis is one form of congenital autosomal recessive ichthyosis. To date, seven causative genes for ARCI have been identified. To understand further the genetic spectrum of the disease, we analyzed a four-generation Iranian family with ARCI that had observable inheritance. Exome sequencing data for one of the affected individuals with ichthyosis from a consanguineous Iranian family...

BACKGROUND Mutations in the ST14 gene, encoding the serine protease matriptase, have been associated with ichthyosis-hypotrichosis syndrome (IHS), a Mendelian disorder with skin and hair manifestations which include, in addition to ichthyosis and hypotrichosis, hypohidrosis and follicular atrophoderma. However, the understanding of the specific consequences of mutations in ST14 on the developme...

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...

Synaptosomal-associated protein 29 (SNAP29) is a t-SNARE protein that is implicated in intracellular vesicle fusion. Mutations in the SNAP29 gene have been associated with cerebral dysgenesis, neuropathy, ichthyosis, and keratoderma syndrome (CEDNIK). In patients with 22q11.2 deletion syndrome, mutations in SNAP29 on the nondeleted chromosome are linked to similar ichthyotic and neurological ph...

A skin permeability barrier is essential for terrestrial animals, and its impairment causes several cutaneous disorders such as ichthyosis and atopic dermatitis. Although acylceramide is an important lipid for the skin permeability barrier, details of its production have yet to be determined, leaving the molecular mechanism of skin permeability barrier formation unclear. Here we identified the ...

Bryophytes were diverse, primitive non vascular amphibious taxa distributed worldwide and form the second largest category of plants. Bryophytes synthesize an array of phytochemicals to combat against the unhospitable environmental conditions including predation, UV radiation, high temperature and pest and pathogens. The present investigation was undertaken to elucidate flavonoids from in vitro...
