BACKGROUND: Mal de Meleda (OMIM# 248300; keratosis palmoplantaris transgrediens) is an autosomal recessive form of palmoplantar keratoderma, clinically characterized by sharp demarcated erythema and hyperkeratosis of the palms and soles that progress with age and extend to the dorsal aspects of the hands and feet. The mal de Meleda is caused by mutations in the SLURP1 gene that encodes secreted lymphocyte antigen 6/urokinase-type plasminogen receptor-related protein 1 (SLURP1). To date no reported cases from Indonesia...

Mutations in SLURP1, a secreted protein of keratinocytes, cause a palmoplantar keratoderma (PPK) known as mal de Meleda. Slurp1 deficiency in mice faithfully recapitulates the human disease, with increased keratinocyte proliferation and thickening of the epidermis on the volar surface of the paws. There has long been speculation that SLURP1 serves as a ligand for a receptor that regulates keratinocyte growth and differentiation. We were intrigued that mutations leading to increased signalling through the epidermal growth factor receptor (EGFR) cause PPK...

Nagashima-type palmoplantar keratosis (NPPK) is an autosomal recessive form of palmoplantar keratoderma (PPK), which is caused by mutations in the SERPINB7 gene. NPPK has only been reported in Japanese and Chinese populations. The present study was conducted on 12 unrelated Chinese patients who were clinically predicted to suffer from NPPK. Mutation screening was performed by direct sequencing of the entire coding regions of SERPINB7, SLURP1, AQP5, CSTA, KRT1 and KRT9 genes. Direct sequencing of SERPINB7 revealed five homozygous founder mutations (c...

Mal de Meleda (MdM, MIM: 248300) is a rare autosomal recessive skin disorder characterized by diffuse palmoplantar keratoderma and transgressive keratosis with onset in early infancy. The gene responsible for MdM, ARS, encodes for Secreted Lys6/Plaur domain-containing protein 1 which is essential for epidermal homeostasis. Tight junctions have been proposed to have two mutually exclusive functions: a fence function which prevents the mixing of membrane proteins between the apical and basolateral membranes; and a gate function which controls the paracellular passage of ions and solutes between cells...

SLURP1, a member of the lymphocyte antigen 6 protein family, is secreted by suprabasal keratinocytes. Mutations in SLURP1 cause a palmoplantar keratoderma (PPK) known as mal de Meleda. SLURP2, another secreted lymphocyte antigen 6 protein, is encoded by a gene located ?20 kb downstream from SLURP1. SLURP2 is produced by suprabasal keratinocytes. To investigate the importance of SLURP2, we first examined Slurp2 knockout mice in which exon 2-3 sequences had been replaced with lacZ and neo cassettes. Slurp2(-/-) mice exhibited hyperkeratosis on the volar surface of the paws (i...

SLURP-1 is a secreted toxin-like Ly-6/uPAR protein found in epithelium, sensory neurons and immune cells. Point mutations in the slurp-1 gene cause the autosomal inflammation skin disease Mal de Meleda. SLURP-1 is considered an autocrine/paracrine hormone that regulates growth and differentiation of keratinocytes and controls inflammation and malignant cell transformation. The majority of previous studies of SLURP-1 have been made using fusion constructs containing, in addition to the native protein, extra polypeptide sequences...

Mal de meleda (MdM), a rare autosomal recessive genodermatosis is characterized by erythema and hyperkeratosis of the palms and soles with a sharp demarcation and that progress with age (progrediens) and extend to the dorsal aspects of the hands and feet (transgrediens). It has been associated with various conditions albeit rarely with congenial cataract. Ocular lens and the skin have the same embryological origins. We hereby present this novel case report of Mal de meleda in association with congenital posterior subcapsular cataract which to the best of our knowledge has not been reported from India before...

BACKGROUND: SLURP1 is the causal gene for Mal de Meleda (MDM), an autosomal recessive skin disorder characterized by diffuse palmoplantar keratoderma and transgressive keratosis. Moreover, although SLURP1 likely serves as an important proliferation/differentiation factor in keratinocytes, the possible relation between SLURP1 and other skin diseases, such as psoriasis and atopic dermatitis, has not been studied, and the pathophysiological control of SLURP1 expression in keratinocytes is largely unknown...

Mal de Meleda is a rare autosomal recessive palmoplantar keratoderma (PPK) disease with an estimated prevalence of 1:100,000. Clinically, the onset of the disease is typically soon after birth and features a transgrediens (plantar surface progressing to dorsal surface) and progrediens (worsening with age) pattern of hyperkeratosis of the palms and soles. The disease can feature other potentially disfiguring effects on the hands and feet that can severely impact function. Histologically, the lesions show hyperkeratosis and acanthosis without epidermolysis in the epidermis, accompanied by perivascular lymphocytic infiltrate in the dermis...

Olmsted syndrome (OS) is a rare genodermatosis classically characterized by the combination of bilateral mutilating transgredient palmoplantar keratoderma (PPK) and periorificial keratotic plaques, but which shows considerable clinical heterogeneity. The disease starts usually at birth or in early childhood. About 73 cases have been reported worldwide. OS is observed in both sexes, although male cases are more frequent. The most suggestive symptoms associate PPK with pseudoainhum and periorificial keratotic plaques...

Mal de Meleda is a rare autosomal recessive genodermatosis caused by mutations in the ARS B (SLURP1) gene, with possible founder effects in the Mediterranean and Adriatic regions. We report an affected individual from Indonesia without known consanguinity in the family, suggesting that SLURP1 gene mutations are ubiquitous. Recognition of the phenotype can be confirmed by genetic testing, thus facilitating genetic counselling.

PURPOSE: Our previous study revealed the immunomodulatory property of the secreted lymphocyte antigen (Ly6)/urokinase-type plasminogen activator receptor (uPAR)-related protein-1 (SLURP1), abundantly expressed in the cornea and associated with the hyperkeratotic disorder Mal de Meleda. Here, we test the hypothesis that SLURP1 modulates the functions of membrane-tethered uPAR by acting as a soluble scavenger of its ligand urokinase-type plasminogen activator (uPA). METHODS: Human corneal limbal epithelial (HCLE) and mouse corneal stromal fibroblast MK/T-1 cells were employed to examine the effect of SLURP1 on cell proliferation and migration...

Meleda disease is an indigenous dermatological disease classified as a hereditary palmoplantar keratoderma. The disease was first described on the island of Mljet, Croatia, by Luko Stulli in 1826. We present a historical review of the literature data throughout the centuries till today. Recently, the gene responsible for the disease has been identified on chromosome 8qter within the cluster of Ly-6 homologous human genes. Various mutations in the secreted LY6/PLAUR-related protein1 gene (SLURP1) located on the aforementioned chromosome were identified as the cause of the disease...

Palmoplantar keratoderma of the Gamborg-Nielsen type (PPK-GN) is a rare autosomal recessive skin disorder described in patients from Sweden. Mal de Meleda (MDM) is also a rare autosomal recessive inherited PPK first reported in 5 families from the island of Meleda. The 2 conditions phenotypically overlap and are characterised by palmoplantar erythematous hyperkeratotic plaques. The genetic background giving rise to PPK-GN has hitherto been unknown, whereas MDM is known to be caused by mutations in the gene encoding secreted Ly-6/uPAR-related protein 1, SLURP-1...

Mutations in SLURP1 cause mal de Meleda, a rare palmoplantar keratoderma (PPK). SLURP1 is a secreted protein that is expressed highly in keratinocytes but has also been identified elsewhere (e.g., spinal cord neurons). Here, we examined Slurp1-deficient mice (Slurp1(-/-)) created by replacing exon 2 with β-gal and neo cassettes. Slurp1(-/-) mice developed severe PPK characterized by increased keratinocyte proliferation, an accumulation of lipid droplets in the stratum corneum, and a water barrier defect. In addition, Slurp1(-/-) mice exhibited reduced adiposity, protection from obesity on a high-fat diet, low plasma lipid levels, and a neuromuscular abnormality (hind-limb clasping)...
