ABCA12: adenosine triphosphate binding cassette A12 HI: harlequin ichthyosis NICU: neonatal intensive care unit INTRODUCTION Harlequin ichthyosis (HI) is a rare autosomal recessive congenital ichthyosis associated with mutations in the keratinocyte lipid transporter adenosine triphosphate binding cassette A12 (ABCA12), leading to disruption in lipid and protease transport into lamellar granules...

objective autosomal recessive congenital ichthyosis (arci) is a rare, heterogenous keratinization disorder of the skin, classically divided into two clinical subtypes, lamellar ichthyosis (li) and nonbullous congenital ichthyosi-formis erythroderma (ncie). lamellar ichtyosis is caused by mutations in the tgm1 gene that encodes transglutaminase 1 enzyme, which is critical for the assembly of the...

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...

Sjögren-Larsson syndrome (SLS) is a rare type of congenital ichthyosis with neurological problems and intellectual disability. Homozygous mutations in ALDH3A2 gene are known to be responsible for this syndrome. Here, we report an Iranian family with congenital SLS bearing a novel two-base-pair deletion within ALDH3A2 genomic sequence. Our finding expands the mutation spectrum of ALDH3A2 that is...

Congenital ichthyoses are life-threatening conditions in humans. We describe here the identification and molecular characterization of a novel recessive mutation in mice that results in newborn lethality with severe congenital lamellar ichthyosis. Mutant newborns have a taut, shiny, non-expandable epidermis that resembles cornified manifestations of autosomal-recessive congenital ichthyosis in ...

BACKGROUND Few studies have investigated ear involvement in nonsyndromic autosomal recessive congenital ichthyosis (ARCI). OBJECTIVES To assess the type and frequency of otologic manifestations of ARCI in patients under follow-up at the pediatric dermatology department of our hospital. MATERIALS AND METHODS We prospectively studied the presence of ear pain, ear itching, tinnitus, otitis, ce...

UNLABELLED Chanarin-Dorfman syndrome (CDS) is a very rare autosomal recessive inherited neutral lipid metabolism disorder associated with congenital ichthyosis and multi-system involvement. Observation of lipid vacuoles in neutrophils (Jordan's anomaly) in peripheral blood smears in patients with ichthyosiform erythroderma is diagnostic. Herein we present 2 siblings with CDS that were referred ...

Keratitis-ichthyosis-deafness (KID) syndrome is a rare congenital disorder characterized by skin lesions, neurosensorial hypoacusia, and keratitis, usually due to the c.148G → A mutation involving the connexin 26 gene. We report on a KID patient who showed the atypical c.101T → C mutation and developed a T-cell lymphoma so far never described in this group of patients.

Dorfman-Chanarin syndrome is a rare, autosomal recessive disorder characterized by congenital ichthyosis and presence of intracellular lipid droplets in most tissues. Here, we present a patient from Turkey, who is the fourth Turkish case in the literature with this syndrome, and we review the previous reported cases. He was also the second case reported with hyperlipidemia.
