Abstract
BACKGROUND Germline autosomal dominant and autosomal recessive mutations in PERP, encoding p53 effector related to PMP-22 (PERP), a component of epidermal desmosomes, have been associated with a spectrum of keratodermas. Monoallelic nonsense mutations cause Olmsted syndrome with severe periorificial keratoderma and palmoplantar keratoderma (PPK). Biallelic recessive frameshift and missense mutations are associated with milder forms of the disease, including generalised erythrokeratoderma and PPK. OBJECTIVES To add new insights into the genotype-phenotype correlations as a consequence of PERP mutations and to provide a comprehensive review of the literature. METHODS Among 26 previously unresolved families within a cohort of 180 extended Iranian families with syndromic or non-syndromic ichthyosis, two families with shared clinical features were examined by whole-exome sequencing and genome-wide homozygosity mapping. Mycological and dermatopathological studies were performed to further characterise their atypical phenotypic presentations. RESULTS In two unrelated multiplex consanguineous families affected by ichthyosis, two novel biallelic PERP variants, NM_022121.5, c.89T > C, p.Leu30Pro and c.466G > C, p.Gly156Arg, located inside of genomic homozygosity regions of the probands were detected. Interestingly, some patients had areas of scaly psoriasiform plaques on the background of generalised ichthyosis that appeared during active cutaneous fungal infections. Mycological examinations of these lesions revealed infections caused by Candida albicans, Epidermophyton floccosum, or Trichophyton rubrum. Histopathology of the psoriasiform lesions shared some features with psoriasis, which when combined with clinical presentation, led to incorrect diagnosis of guttate psoriasis or pustular psoriasis. CONCLUSIONS PERP variants in ichthyosis patients can confer susceptibility to recalcitrant cutaneous fungal infections. Additionally, patients with episodic psoriasiform dermatitis in the setting of keratoderma should be considered for PERP genotyping and cutaneous fungal examinations.

Abstract
Pseudoxanthoma elasticum (PXE) is a multisystem disorder characterized by ectopic mineralization of connective tissues with primary manifestations in the skin, eyes and the cardiovascular system. The classic forms of PXE are caused by mutations in the ABCC6 gene encoding the ABCC6 protein, expressed primarily in the liver. Cutis laxa (CL) manifests with loose and sagging skin with loss of recoil. In 2009 we investigated a 19-year-old patient with overlapping cutaneous features of PXE and CL, together with alpha thalassaemia. Genetic analysis failed to identify pathogenic mutations in ABCC6. More recently we developed a gene-targeted panel of next-generation sequencing technology. This panel has 29 genes, 22 of which, including ABCC6 and GGCX, are associated with ectopic mineralization phenotypes. Mutation analysis in the patient identified two heterozygous GGCX mutations: c.200_201delTT in exon 2 and c.763G>A, p.V255M in exon 7. The GGCX gene encodes a γ-glutamyl carboxylase necessary for activation of blood coagulation factors in the liver. The p.V255M mutation was previously reported to result in reduced γ-glutamyl carboxylase activity in vitro, while the c.200_201delTT mutation is novel. Previous studies reported that mutations in GGCX cause overlapping PXE/CL skin phenotypes in association with or without multiple vitamin K-dependent coagulation factor deficiency. Our patient had loose redundant skin, moderate-to-severe angioid streaks and characteristic calcification of elastic structures in the mid dermis, consistent with PXE/CL overlap, but no coagulation abnormalities. Our studies expand the GGCX mutation landscape in patients with PXE-like phenotypes.

Abstract
Pachyonychia congenita (PC) is a rare autosomal dominant disorder characterized by nail dystrophy and palmoplantar keratoderma with severe plantar pain affecting quality of life. There is no effective treatment. Heterozygous mutations in the keratin genes KRT6A, KRT6B, KRT6C, KRT16 and KRT17 have been reported as a cause of PC. Herein we present a female patient with an amino acid substitution mutation in KRT6A (c.1381G>A, p.Glu461Lys in exon 7) and classic features of PC associated with oral leucokeratosis and follicular hyperkeratosis. We also demonstrate successful treatment of the patient with rosuvastatin. A 3.6-mm reduction in plantar callosity thickness was demonstrated by sonography. Our patient also experienced significant pain relief that allowed her to increase physical activity (Children's Dermatology Life Quality Index score dropped nine points following treatment). Collectively, these improvements suggest that rosuvastatin may offer a promising treatment for PC. What's already known about this topic? Pachyonychia congenita (PC) is an autosomal dominant disease characterized by nail dystrophy and painful plantar keratoderma. Keratolytics, emollients, retinoids and steroids have been used for treatment but with limited benefits. What does this study add? A patient with PC who had a KRT6A mutation was treated with rosuvastatin with significant improvement in plantar hyperkeratosis and pain. Statins could be a promising treatment for PC with long-term safety, but further studies are needed.

Abstract
Recessive dystrophic epidermolysis bullosa (RDEB; OMIM #226600) is one of the most devastating subtypes of epidermolysis bullosa, a group of skin and mucous membrane blistering disorders often associated with extracutaneous manifestations. RDEB is caused by mutations in COL7A1, the gene encoding type VII collagen (C7), and to date over 700 different mutations in the 8835 nucleotides constituting the open reading frame or adjacent exon-intron boundaries of COL7A1 have been described. We used targeted next-generation sequencing to identify seven previously unreported mutations in a cohort of 17 Mexican patients who were diagnosed with RDEB based on clinical presentation and immunoepitope mapping. Our study expands the spectrum of mutations identified in this cohort, including those suitable for emerging therapies reliant on precise genotyping.

Abstract
Infantile systemic hyalinosis (ISH) is an extremely rare genodermatosis, characterized by thickened skin, joint contractures and subcutaneous nodules. ISH is caused by mutations in the CMG2 gene, which encodes a protein of unknown function. In this report, we describe a patient with ISH, who was a twin born to a consanguineous Iranian couple, and who demonstrated unusual skin findings in addition to the characteristic features of ISH. Mutation analysis disclosed a homozygous deletion mutation, c.1074delT in CMG2, resulting in a frameshift and premature termination codon 50 amino acids downstream of the deletion. This information adds to the recurring nature of this mutation in ISH, with implications for genetic counselling in extended families with a history of this disease.
