Abstract
The ichthyosis, also called disorders of keratinization or cornification, are heterogeneous group of disorders characterized by a generalized scaling of the skin of varying severity. The majority of ichthyosis is inherited but acquired forms can develop in the setting of malignancy, autoimmune or infectious disease, and nutritional deficiency. Autosomal recessive congenital ichthyosis, which include lamellar ichthyosis, congenital ichthyosiform erythroderma, and harlequin ichthyosis, are rare; their overall incidence has been estimated at approximately 1 in 300,000 births. In this article, we described four cases of congenital ichthyosis, their potential complications, causes of morbidity and mortality, and discussed the management and importance of genetic testing for diagnosis as definitive diagnosis is important for long-term management and counseling of the parents.

Abstract
Background and Objectives: Lamellar ichthyosis is a rare skin disease characterized by large, dark brown plate-like scales on the entire body surface with minimum or no erythema. This phenotype is frequently associated with a mutation in the TGM1 gene, encoding the enzyme transglutaminase 1 which plays a catalytic role in the formation of the cornified cell envelop. The present study aimed to carry out clinical and genetic characterization of the autosomal recessive lamellar ichthyosis family from Balochistan. Materials and Methods: A consanguineous family with lamellar ichthyosis was enrolled from Balochistan, Pakistan. PCR amplification of all the exons and splice site junctions of the TGM1 gene followed by Sanger sequencing was performed on the genomic DNA. The identified variant was checked by In silico prediction tools to evaluate the effect of the variant on protein. Results: Sanger sequencing identified a homozygous nonsense variant c.131G >A (p.Trp44*) in the TGM1 gene that segregated in the autosomal recessive mode of inheritance in the family. The identified variant results in premature termination of transcribed mRNA and is predicted to cause a truncated or absent translation product transglutaminase-1 (TGase-1) accompanied by loss of catalytic activity, causing a severe clinical phenotype of lamellar ichthyosis in the patients. Conclusions: Here, we report a consanguineous lamellar ichthyosis family with a homozygous nonsense variant in the TGM1 gene. The variant is predicted as pathogenic by different In silico prediction tools.

Abstract
Mutations in genes such as transglutaminase-1 (TGM1), which are responsible for the formation and normal functioning of a lipid barrier, lead to the development of autosomal recessive congenital ichthyosis (ARCI). ARCIs are characterized by varying degrees of hyperkeratosis and the presence of scales on the body surface since birth. The quality of life of patients is often significantly affected, and in order to alleviate the manifestations of the disease, symptomatic therapy with moisturizers, keratolytics, retinoids and other cosmetic substances is often used to improve the condition of the patients' skin. Graft transplantation is commonly used to correct defects of the eye. However, these approaches offer symptomatic treatment that does not restore the lost protein function or provide a long-term skin barrier. Gene and cell therapies are evolving as promising therapy for ARCIs that can correct the functional activity of altered proteins. However, these approaches are still at an early stage of development. This review discusses current studies of gene and cell therapy approaches for various types of ichthyosis and their further prospects for patient treatment.

Abstract
Background Ichthyosis is a heterogeneous group of Mendelian cornification disorders that includes syndromic and non-syndromic forms. Autosomal Recessive Congenital Ichthyosis (ARCI) and Ichthyosis Linearis Circumflexa (ILC) belong to non-syndromic forms. Syndromic ichthyosis is rather a large group of heterogeneous diseases. Overlapping phenotypes and genotypes between these disorders is a major characteristic. Therefore, determining the specific genetic background for each form would be necessary.
Methods A total of 11 Tunisian patients with non-syndromic (8 with ARCI and 2 with ILC) and autosomal syndromic ichthyosis (1 patient) were screened by a custom Agilent HaloPlex multi-gene panel and the segregation of causative mutations were analyzed in available family members. Results Clinical and molecular characterization, leading to genotype–phenotype correlation in 11 Tunisian patients was carried out. Overall, we identified 8 mutations in 5 genes. Thus, in patients with ARCI, we identified a novel (c.118T > C in NIPAL4) and 4 already reported mutations (c.534A > C in NIPAL4; c.788G > A and c.1042C > T in TGM1 and c.844C > T in CYP4F22). Yellowish severe keratoderma was found to be associated with NIPAL4 variations and brachydactyly to TGM1 mutations. Two novel variations (c.5898G > C and c.2855A > G in ABCA12) seemed to be features of ILC. Delexon13 in CERS3 was reported in a patient with syndromic ichthyosis. Conclusions Our study further extends the spectrum of mutations involved in ichthyosis as well as clinical features that could help directing genetic investigation.

Abstract
The Mendelian disorders of cornification consist of a highly heterogeneous group of diseases, and the majority of nonsyndromic cases belong to the family of autosomal recessive congenital ichthyosis. Mutations in SDR9C7 have been associated with autosomal recessive congenital ichthyosis, and clinical manifestations include mild to moderately dry, scaly skin with or without hyperkeratosis, palmoplantar keratoderma, and erythroderma. SDR9C7, with short-chain dehydrogenase and/or reductase activity, is known as nicotinamide adenine dinucleotide‒ or nicotinamide adenine dinucleotide phosphate‒dependent oxidoreductase and has been shown to be involved in the final step of epidermal lipid barrier formation by covalent binding of acylceramide to the cornified envelope. In this study, we present the clinical and molecular description of 19 patients with autosomal recessive congenital ichthyosis in five consanguineous families with SDR9C7 mutations. We also downregulated the expression of SDR9C7 in keratinocytes using the small interfering RNA technique in three-dimensional organotypic skin constructs. Our results demonstrated morphological and histological abnormalities in these constructs ex vivo, similar to those observed in patients with ichthyosis. Moreover, the results from keratinocyte migration and epidermal dye penetration assays provided evidence for the role of SDR9C7 in the disease pathomechanism. Collectively, our results indicate that SDR9C7 deficiency by itself is sufficient to disrupt epidermal barrier function leading to ichthyotic phenotype.

Abstract
Background The NIPAL4 gene is described to be implicated of Congenital Ichthyosiform Erythroderma (CIE). It encodes a magnesium transporter membrane‐associated protein, hypothetically involved in epidermal lipid processing and in lamellar body formation. The aim of this work is to investigate the causative mutation in a consanguineous Tunisian family with a clinical feature of CIE with a yellowish severe palmoplantar keratoderma. Methods Four patients were dignosed with CIE. The blood samples were collected from patients and all members of their nuclear family for mutation analysis. The novel mutation of NIPAL4 gene was analysed with several software tools to predict its pathogenicity. Then, the secondary structure and the 3D model of ichthyn was generated in silico. Results The sequencing analysis of the NIPAL4 gene in patients revealed a novel homozygous missense mutation c.534A>C (p.E178D) in the exon 4. Bioinformatic tools predicted its pathogenicity. The secondary structure prediction and the 3D model construction expected the presence of 9 transmembrane helices and revealed that mutation p.E178D was located in the middle of the second transmembrane helices. Besides, the 3D model construction revealed that the p.E178D mutation is inducing a shrinking in the transport channel containing the mutated NIPA4 protein. Conclusion We found a homozygous mutation in exon 4 of NIPAL4 c.534A>C (p.E178D), which was identified for the first time in our study. Bioinformatic investigations supported its involvement in the phenotype of patients with CIE. Interestingly, this mutation was located in the hypothetical transport channel cavity and leads to changes in the channel architecture, which would probably affect its transport function.

Abstract
Background: Lamellar ichthyosis is an autosomal recessive type of rare skin disorders characterized with defective epidermis leading hyperkeratosis with brownish-gray scales over the body. These patients are born as collodion babies and may also exhibit additional features like erythema, ectropion, and eclabium. This disease is mainly caused by homozygous and compound heterozygous alterations in transglutaminase 1 encoding gene (TGM1), which is located on 14q12. Case presentation: This study reports the genetic analysis of a 4-year Saudi girl presenting lamellar ichthyosis. She was the first child of unrelated parents. The family had no previous history of the disease phenotype. She was born as a collodion baby without any prenatal complications. At the time of this study she had developed rough scaly skin on her legs, arms and trunk regions with thick palms and soles. Whole exome sequencing (WES) followed by Sanger sequence validation identified a novel compound heterozygous variant in TGM1 gene. The paternal variant was a missense transition (c.1141G>A; p.Ala381Thr) present at exon 7, while maternal variant (c.758-1G>C) was present at the intron4-exon5 boundary. To the best of our knowledge these variants had not been reported before in TGM1 gene. Conclusion: In isolated and inbred populations, homozygous variants are identified more frequently; however, our results suggest that compound heterozygous variants should also be considered especially when the marriages are not consanguineous.

Abstract
Abstract
Introduction: Autosomal recessive congenital ichthyosis is a non-syndromic ichthyosis, with a genetic background of mutations in 9 genes. This case series presents clinical and paraclinical particularities of 3 Romanian ARCI patients with NIPAL4 mutation c.527C>A.
Material and methods: Three Caucasian patients were investigated, two sisters and an unrelated female patient, aged 47, 49, and 42 respectively. Skin anomalies were recorded and documented photographically; peripheral blood samples were harvested for DNA extraction and gene analysis. Skin biopsies were used for histological assessment, electron microscopy, and evaluation of in situ transglutaminase 1 activity.
Results: All patients presented with generalized ichthyosis, palmoplantar keratoderma, normal hair shafts, and significant oral manifestations. Natural evolution was relatively stable in all cases, without phenotype changing. Medical treatment with retinoids in patients 1 and 2 resulted in normalisation of the skin condition.
Histological samples showed hyperkeratosis, acanthosisand perivascular inflammatory infiltrates in the dermis. Positive findings of transglutaminase 1 in situ activity excluded TGM1 deficiency. Direct sequencing of amplicons revealed one homozygous mutation in exon 4, a c.527C>A missense mutation.
Conclusions: This is the first report of the hotspot mutation NIPAL4 c.527C>A in Romanian autosomal recessive congenital ichthyosis patients. The phenotype was similar to that reported in the literature, while transglutaminase 1 activity in situ assay detected differences in enzyme distribution between patients bearing the same mutation but different phenotypes. Based on the current data, NIPAL4 mutations are more frequent than TGM1 mutations in Romanian patients with autosomal recessive congenital ichthyosis.

Abstract
Congenital ichthyosiform erythroderma is an autosomal recessive ichthyosis characterized by severe scaling and erythroderma. We report a family of three siblings who were all born with a collodion membrane and presented with diffuse scaling and pruritus. All three children subsequently developed chronic cutaneous dermatophyte infections requiring oral antifungals. One child developed superinfection with methicillin-resistant Staphylococcus aureus requiring antibiotics.

Abstract
Collodion baby (CB) is normally diagnosed at the time of birth and refers to a newborn infant that is delivered with a lambskin-like membrane encompassing the total body surface. CB is not a specific disease entity, but is a common phenotype in conditions like harlequin ichthyosis, lamellar ichthyosis, nonbullous congenital ichthyosiform erythroderma, and trichothiodystrophy. We report a CB that was brought to our department and later diagnosed to have TGM1 gene c.984+1G>A mutation. However, it could not be ascertained whether the infant had lamellar ichthyosis or congenital ichthyosiform erythroderma (both having the same mutation). The infant was lost to follow-up.

Abstract
Non-bullous congenital ichthyosiform erythroderma (NBCIE) is a hereditary disorder of keratinization caused by pathogenic variants in genes encoding enzymes important to lipid processing and terminal keratinocyte differentiation. Impaired function of these enzymes can cause pathologic epidermal scaling, significantly reduced skin barrier function. In this study, we have performed a focused, genetic analysis of a probrand affected by NBCIE and extended this to his consanguineous parents. Targeted capture and next-generation sequencing was performed on NBCIE associated genes in the proband and his unaffected consanguineous parents. We identified a homozygous nonsense variant c.814C>T (p.Arg272*) in ALOXE3 (NM_001165960.1) in the proband and discovered that his parents are both heterozygous carriers of the variant. The clinical manifestations of the proband’s skin were consistent with NBCIE, and detailed histopathological assessment revealed epidermal bulla formation and Majocchi’s granuloma. Infection with Trichophyton rubrum was confirmed by culture. The patient responded to oral terbinafine antifungal treatment. Decreased skin barrier function, such as that caused by hereditary disorders of keratinization, can increase the risk of severe cutaneous fungal infections and the formation of Majocchi’s granuloma and associated alopecia. Patients with NBCIE should be alerted to the possible predisposition for developing dermatophytoses and warrant close clinical follow-up.

Abstract
Lamellar ichthyosis (LI), considered an autosomal recessive monogenic genodermatosis, has an incidence of approximately 1 in 250,000. Usually associated with mutations in the transglutaminase gene (
TGM1), mutations in six other genes have, less frequently, been shown to be causative. Two siblings, born in a collodion membrane, presented with fish like scales all over the body. Karyotyping revealed duplication of the chromosome arm on 22q12+ in the father and two siblings. Whole exome sequencing revealed a homozygous p.Gly218Ser variation in
TGM1; a variation reported earlier in an isolated Finnish population in association with autosomal recessive non-syndromic ichthyosis. This concurrence of a potentially benign 22q12+ duplication and LI, both rare individually, is reported here likely for the first time.

Abstract
Harlequin ichthyosis (HI) is a rare type of congenital ichthyosis associated with poor survival. We report, with photographic record, a male baby born with HI. To the best of our knowledge, this is the first reported case of HI in Saudi Arabia, where the child has survived beyond 7 years. The baby was born at 37 weeks of gestation from consanguineous parents with no inherited skin disorder in the family. The mother was 28 years old with three normal previous pregnancies and healthy babies. At birth, the baby's skin had thick scales separated by deep fissuring. He was managed in intensive care with supportive treatment and frequent application of lubricants, emollients and urea cream. The skin gradually became softened, and began to shed after 6 weeks. After 8 months of inpatient management, he was discharged. He is currently 7 years old and is still being treated for non-bullous congenital ichthyosiform erythroderma.

Abstract
Ichthyoses are a heterogenous group of hereditary keratinization disorders that share in common the accumulation & shedding of large amounts of hyperkeratotic epidermis. Early reports of ichthyosis in the Indian and Chinese literature date back to several hundred years. X-linked recessive ichthyosis (XLI) is a common disorder of keratinization and affects males who inherit an X-chromosome having a steroid sulphatase genetic mutation. In the present communication we report a case of XLI and dystrophic epidermolysis bullosa in the same patient. To the best of our knowledge it has been reported only once before.

Abstract
Autosomal recessive congenital ichthyosis (ARCI) is a heterogeneous group of skin barrier diseases due inter alia to mutations in transglutaminase-1 (TGM1), in lipoxygenases (LOXs) of the hepoxilin pathway, and in ichthyin, a putative Mg(2+) transporter encoded by the NIPAL4 gene. In search of a common pathogenic pathway for ARCI, we investigated the epidermal expression of TGM1, 12R-LOX, eLOX-3, and ichthyin in skin biopsies from four healthy controls and nine patients with ARCI. In healthy skin, TGM1, ichthyin, and the LOX enzymes were predominantly expressed in the upper epidermis where colocalization signals could also be demonstrated by in situ proximity ligation assay. In patients with ALOX12B mutations and abnormal 12R-LOX expression, the colocalization signal for eLOX-3 and TGM1 was increased 4-fold. In contrast, patients with NIPAL4 mutations and abnormal ichthyin expression showed increased 12R-LOX and eLOX-3 staining and a colocalization signal of these LOXs that was three times the normal intensity. Treatment of these patients with a retinoid-mimetic drug, liarozole, normalized the expression of 12R-LOX and attenuated the colocalization signal. Altogether, our data indicate that ichthyin and TGM1 are functionally closely related in the lipid processing and that this metabolic pathway can be modified by retinoids.

Abstract
ADAM17 (a disintegrin and metalloproteinase 17) is ubiquitously expressed and cleaves membrane proteins, such as epidermal growth factor receptor (EGFR) ligands, l-selectin, and TNF, from the cell surface, thus regulating responses to tissue injury and inflammation. However, little is currently known about its role in skin homeostasis. We show that mice lacking ADAM17 in keratinocytes (A17(ΔKC)) have a normal epidermal barrier and skin architecture at birth but develop pronounced defects in epidermal barrier integrity soon after birth and develop chronic dermatitis as adults. The dysregulated expression of epidermal differentiation proteins becomes evident 2 d after birth, followed by reduced transglutaminase (TGM) activity, transepidermal water loss, up-regulation of the proinflammatory cytokine IL-36α, and inflammatory immune cell infiltration. Activation of the EGFR was strongly reduced in A17(ΔKC) skin, and topical treatment of A17(ΔKC) mice with recombinant TGF-α significantly improved TGM activity and decreased skin inflammation. Finally, we show that mice lacking the EGFR in keratinocytes (Egfr(ΔKC)) closely resembled A17(ΔKC) mice. Collectively, these results identify a previously unappreciated critical role of the ADAM17-EGFR signaling axis in maintaining the homeostasis of the postnatal epidermal barrier and suggest that this pathway could represent a good target for treatment of epidermal barrier defects.

Abstract
Only ~270 cases of collodion babies have been reported in the literature since 1892. As the name suggests, the term "collodion baby" refers to a phenotype that can be characterized by a yellow, shiny, tight parchment-like membrane stretched over the skin. Although the collodion membrane is only an evanescent condition of the newborn, neonatal complications can occur in 45% of all collodion babies, leading to a mortality rate of ~11% in the first few weeks of life. Most children born as collodion babies will spontaneously desquamate within 2 weeks, but may be as long as 3 months. Eventually, these children develop signs of one of several types of ichthyosis, which gives the skin the appearance of "fish scales." We report a unique case of a Caucasian male that was born as a Collodion baby at the University of Kentucky Children's Hospital in Lexington, Kentucky. Although the impairment of the skin barrier function put the patient at risk for a number of complications, he improved significantly after being treated with emollients and antibiotics. In contrast to previous findings, we found that skin emollients were beneficial and did not increase the risk of infection.

Abstract
BACKGROUND Inherited ichthyoses belong to a large, clinically and etiologically heterogeneous group of mendelian disorders of cornification, typically involving the entire integument. Over the recent years, much progress has been made defining their molecular causes. However, there is no internationally accepted classification and terminology. OBJECTIVE We sought to establish a consensus for the nomenclature and classification of inherited ichthyoses. METHODS The classification project started at the First World Conference on Ichthyosis in 2007. A large international network of expert clinicians, skin pathologists, and geneticists entertained an interactive dialogue over 2 years, eventually leading to the First Ichthyosis Consensus Conference held in Sorèze, France, on January 23 and 24, 2009, where subcommittees on different issues proposed terminology that was debated until consensus was reached. RESULTS It was agreed that currently the nosology should remain clinically based. "Syndromic" versus "nonsyndromic" forms provide a useful major subdivision. Several clinical terms and controversial disease names have been redefined: eg, the group caused by keratin mutations is referred to by the umbrella term, "keratinopathic ichthyosis"-under which are included epidermolytic ichthyosis, superficial epidermolytic ichthyosis, and ichthyosis Curth-Macklin. "Autosomal recessive congenital ichthyosis" is proposed as an umbrella term for the harlequin ichthyosis, lamellar ichthyosis, and the congenital ichthyosiform erythroderma group. LIMITATIONS As more becomes known about these diseases in the future, modifications will be needed. CONCLUSION We have achieved an international consensus for the classification of inherited ichthyosis that should be useful for all clinicians and can serve as reference point for future research.

Abstract
The aim of this study is to estimate annual, per patient, health care costs for congenital ichthyoses (CI). We conducted a cost analysis through an online survey posted on the Foundation for Ichthyosis and Related Skin Types Website. We assessed cutaneous disease severity, via the previously validated Congenital Ichthyosis Severity Index (CISI), demographics, and CI type. We estimated direct health care costs: prescription and over-the-counter medications, outpatient visits, and emergency department and hospital visit costs; and indirect costs: earnings lost owing to absences from work because of CI-related illness. The CI subjects of our study (n=224) consumed a mean (SD) of $3,192 ($7,915) annually. Direct costs accounted for 90%, whereas indirect costs accounted for 10%. These costs resulted in an estimated annual cost of $37 MM/year (excluding ichthyosis vulgaris) of which $17 MM is borne out-of-pocket by patients. Depending on the CI diagnosis, patients were responsible for 30-51 cents of every dollar of mean annual medical care costs. Our estimated annual CI costs are comparable to cutaneous lymphoma. More effective treatments for CI would help minimize this burden. Traditional insurance products do not appear to substantially alleviate the financial burden of disease, as a significant amount is from out-of-pocket expenses.

Abstract
Ichthyoses constitute a large group of cornification disorders that affect the entire integument. The skin is characterized by visible scaling and in many cases by inflammation, for example, in bullous/keratinopathic ichthyosis or Netherton syndrome. From the viewpoint of classification it is useful to distinguish non-syndromic from syndromic types of ichthyosis. Ichthyosis vulgaris and recessive X-linked ichthyosis are common disorders - often of delayed onset, in contrast to congenital ichthyoses, which belong to the group of rare diseases and present at birth with either the features of collodion membrane or congenital ichthyosiform erythroderma. The diagnostic steps are based on clinical data, analyses such as the steroid sulfatase activity test, skin biopsies, and genetic results. However, the dramatic increase in knowledge about the pathophysiology of these conditions has not led to a curative therapy so far. The therapeutic management is multidisciplinary and involves ichthyosis patient organizations in many countries. The mainstay of treatment remains with moisturizing creams containing, for example, urea, lactic acid and other humectants and keratolytics, regular bathing, and mechanical scale removal. Patients with lamellar ichthyosis or ichthyosiform erythroderma in particular profit from oral therapy with retinoids or retinoic acid metabolism-blocking agents.

Abstract
BACKGROUND Lamellar ichthyosis (LI) is a congenital recessive skin disorder characterized by generalized scaling and hyperkeratosis. The pathology may be caused by mutations in transglutaminase 1 (TGM1) gene that encodes an enzyme critical for terminally differentiating keratinocytes. Because of evidences that transglutaminase enzymes are involved in programmed cell death, we investigated morphological and biochemical apoptotic parameters in cultured skin fibroblasts from a patient with a severe LI and homozygous for the TGM1 R142H mutation. METHOD The principle apoptotic signals (mitochondrial membrane potential, analysis of oxygen consumption, DNA fragmentation and Bax/Bcl-2 gene expression) were analyzed in cultured fibroblasts from a LI patient, his mother (TGM1 mutation carrier) and a control subject. RESULTS LI fibroblasts showing a reduction of fibronectin expression evidenced a strong inhibition of oxygen consumption, a dramatic drop in the mitochondrial membrane potential (Delta psi(m)), and a higher apoptotic index. CONCLUSION The present results suggest a possible connection between the alterations in the keratinization process leading to LI and the observed increased fibroblast apoptosis.

Abstract
A scaling disorder specific to Golden Retriever dogs has been recognized by both dermatologists and pathologists, but to date has not been well characterized. At the University of Pennsylvania's Laboratory of Toxicology and Pathology, 46 cases of ichthyosis were diagnosed histologically in Golden Retriever dogs from January 2004 to January 2007. A total of 22 dogs had skin lesions documented at younger than 1 year of age; 3 dogs between 1 and 2 years of age; 13 dogs developed lesions at older than 2 years; and the time of onset was unknown for 8 dogs. A total of 25 dogs were female, and 21 were male. All dogs had strikingly similar histopathologic changes that consisted of mild to moderate laminar orthokeratotic hyperkeratosis with an absence of epidermal hyperplasia and dermal inflammation. Ultrastructural analysis using a ruthenium tetroxide fixation method was performed on punch biopsy samples from 5 dogs and compared with 2 control dogs (1 clinically and histologically normal sibling of an affected dog and 1 Cairn Terrier). All affected dogs had retained and convoluted membranes with crystalline structures in the stratum corneum. Scattered keratinocytes in the granular cell layer had prominent, clear, membrane-bound, cytoplasmic vacuoles. Pedigree analysis of 14 dogs was compatible with autosomal recessive inheritance, but incomplete dominance could not be ruled out. This unique hyperkeratotic/scaling disorder in Golden Retrievers has distinctive clinical, histologic, and ultrastructural features, which are consistent with a primary cornification defect.

Abstract
Many of the ichthyoses are associated with inherited disorders of lipid metabolism. These disorders have provided unique models to dissect physiologic processes in normal epidermis and the pathophysiology of more common scaling conditions. In most of these disorders, a permeability barrier abnormality "drives" pathophysiology through stimulation of epidermal hyperplasia. Among primary abnormalities of nonpolar lipid metabolism, triglyceride accumulation in neutral lipid storage disease as a result of a lipase mutation provokes a barrier abnormality via lamellar/nonlamellar phase separation within the extracellular matrix of the stratum corneum (SC). Similar mechanisms account for the barrier abnormalities (and subsequent ichthyosis) in inherited disorders of polar lipid metabolism. For example, in recessive X-linked ichthyosis (RXLI), cholesterol sulfate (CSO(4)) accumulation also produces a permeability barrier defect through lamellar/nonlamellar phase separation. However, in RXLI, the desquamation abnormality is in part attributable to the plurifunctional roles of CSO(4) as a regulator of both epidermal differentiation and corneodesmosome degradation. Phase separation also occurs in type II Gaucher disease (GD; from accumulation of glucosylceramides as a result of to beta-glucocerebrosidase deficiency). Finally, failure to assemble both lipids and desquamatory enzymes into nascent epidermal lamellar bodies (LBs) accounts for both the permeability barrier and desquamation abnormalities in Harlequin ichthyosis (HI). The barrier abnormality provokes the clinical phenotype in these disorders not only by stimulating epidermal proliferation, but also by inducing inflammation.

Abstract
Non-bullous congenital ichthyosis erythroderma (NCIE) and lamellar ichthyosis (LI) are characterized by mutations in 12R-lipoxygenase (12R-LOX) and/or epidermal lipoxygenase 3 (eLOX3) enzymes. The eLOX3 lacks oxygenase activity, but is capable of forming hepoxilin-type products from arachidonic acid-derived hydroperoxide from 12R-LOX, termed 12R-hydroperoxyeicosa-5,8,10,14-tetraenoic acid (12R-HpETE). Mutations in either of two enzymes lead to NCIE or LI. Moreover, 12R-LOX-deficient mice exhibit severe phenotypic water barrier dysfunctions. Here, we demonstrate that 12R-HpETE can also be transformed to 8R-HXA(3) by hepoxilin A(3) (HXA(3)) synthase (12-lipoxygenase), which exhibits oxygenase activity. We also presented a novel form of ichthyosis in a patient, termed hepoxilin A(3) synthase-linked ichthyosis (HXALI), whose scales expressed high levels of 12R-LOX, but were deficient of HXA(3) synthase.
