Motivation: Identifying drug-target protein interaction is a crucial step in the process of drug research and development. Wet-lab experiment are laborious, time-consuming and expensive. Hence, there is a strong demand for the development of a novel theoretical method to identify potential interaction between drug and target protein. Read More

​Multicentric osteolysis nodulosis and arthropathy (MONA) is an infrequently described autosomal recessive skeletal dysplasia characterized by progressive osteolysis and arthropathy. Inactivating mutations in MMP2, encoding matrix metalloproteinase-2, are known to cause this disorder. Fifteen families with mutations in MMP2 have been reported in literature. Read More

Infantile systemic hyalinosis (ISH) is a rare autosomal recessive disorder caused by a mutation in the ANTXR2 gene encoding a transmembranous protein involved in endothelial development. The ANTXR2 (also known as CMG2) locus is on chromosome 4q21. ISH is a common disorder in children of consanguineous parents in Arab countries. Read More

Torg and Winchester syndromes and patients reported by Al-AqeelSawairi as well as nodulosis-arthropathy-osteolysis (NAO) patients, patients with multicentric NAO share autosomal recessive inheritance. The common presenting symptomatology includes progressive osteolysis chiefly affecting the carpal, tarsal and interphalangeal joints. Here, we report a patient with Torg syndrome. Read More

The "vanishing bone" syndromes represent a group of rare skeletal disorders characterized by osteolysis and joint destruction, which can mimic severe rheumatoid arthritis. Winchester syndrome was one of the first recognized autosomal-recessive, multicentric forms of the disorder. It was originally described nearly 50 years ago in two sisters with a severe crippling osteolysis. Read More

The two well-described osteolysis syndromes associated with matrix metalloproteinase-2 deficiency and mutations in the metalloproteinase-2 gene are Torg-Winchester syndrome and nodulosis-arthropathy-osteolysis variant. They are characterized by carpal-tarsal destruction, subcutaneous nodules, and generalized osteoporosis and show autosomal recessive inheritance. Herein, we report two siblings affected with a novel mutation in matrix metalloproteinase 2 gene and discuss their clinical and radiographic findings. Read More

Torg-Winchester syndrome, which includes nodular arthropathy with osteolysis (OMIM 605156), is a condition associated with generalized osteoporosis. On the basis of usefulness of pamidronate in conditions with osteoporosis, we hypothesized that the drug will improve osteolysis and/or osteoporosis in this condition. After obtaining informed consent from the parents, two siblings affected with Torg-Winchester syndrome were administered intravenous pamidronate over a period of 3 years. Read More

We identified mutations in the MMP2 gene in a patient with Torg syndrome that resulted in complete loss of MMP2 activity. MMP2 mutations were previously identified in patients with NAO and Winchester syndrome. Read More

The 2001 International Classification of Constitutional Disorders of Bone has included in the group of multicentric hands and feet osteolysis syndromes three autosomal recessive inherited disorders: Winchester, Torg and nodulosis-arthropathy-osteolysis (NAO) syndromes. Nosographic delineations of these rare syndromes are difficult to define, and there is no consensus. In 2001, two mutations in the matrix metalloproteinase 2 gene (MMP2) have been identified in two families with a NAO phenotype. Read More

The inherited osteolysis syndromes are a heterogeneous group of skeletal disorders whose classification is still uncertain. Three osteolysis syndromes show autosomal recessive inheritance and multicentric involvement: Torg syndrome (OMIM 259600), Winchester syndrome (OMIM 277950) and Nodulosis-Arthropathy-Osteolysis syndrome (NAO; OMIM 605156). The 2001 Nosology of the International Skeletal Dysplasia Society (Hall CM, Am J Med Genet 2002: 113: 65) classifies NAO as a variant of Torg syndrome, while Winchester syndrome is considered as a separate disorder.

Winchester syndrome is a rare genetic disorder, one of the inherited osteolysis disorders which are a group of diseases characterized by destruction and resorption of affected bones with consequent skeletal deformities and functional impairment. The syndrome is characterized by dissolution of carpal and tarsal bones with generalized osteoporosis, progressive joint contractures, short stature, peripheral corneal opacities, and coarse facial features, though there is variability within the clinical features. Phenotypic heterogeneity of cutaneous features are also reported to date of diffusely thickened leathery skin, hypertrichosis, patches of hyperpigmented, hypertrichotic leathery skin in annular or linear distribution, widespread acne, subcutaneous nodules, and gingival hypertrophy.

Winchester syndrome was first described in 1969 and since then nine patients have been reported in the literature. The syndrome is characterized by short stature, coarse face, corneal opacities, generalized osteolysis and progressive painful arthropathy with joint stiffness and contractures of distal phalanges in combination with skin changes. The etiology is unknown. Read More

The mucopolysaccharidoses are a group of inherited lysosomal storage diseases that are caused by a deficiency of specific enzymes. The acid mucopolysaccharides are stored in tissue and excreted in large quantities in the urine. The storage of this material leads to effects on a wide variety of tissues and to remarkable changes in morphologic features. Read More

Two new familial cases of Winchester syndrome with the characteristic features allowed to be more explicit on a few data of this syndrome. As reported in a previous paper an abnormal oligosaccharide was detected in urine of patients but the pathological significance of this oligosaccharide must be discussed and its finding in patients with Winchester syndrome does not lead to further elucidation of the aetiology of this condition. Cultured fibroblasts were obtained from a skin biopsy performed in thickened area. Read More

We present our findings in two unrelated patients with the characteristic clinical and radiological features of the Winchester syndrome. The histological findings in gum and skin biopsies taken from one of the subjects, indicated excessive collagen turnover (active phagocytosis, an active endoplasmic reticulum, and an abundance of fibrillogranular material of probable collagen origin). An abnormal oligosaccharide was detected in urine from both patients which was identified as a trisaccharide containing one fucose and two galactose residues. Read More

A family is described which has exhibited in four generations a bizarre form of arthritis mutilans and osteolysis, the features of which seem to fit most closely with a diagnosis of hereditary multicentric osteolysis, a subgroup of idiopathic multicentric osteolysis. The differential diagnosis of arthritis mutilans associated with osteolysis is discussed; this includes a wide variety of disorders ranging from rheumatoid arthritis to rare conditions such as the Winchester syndrome.

The Winchester syndrome, a rare inherited disorder, is characterized by dwarfism, carpal-tarsal osteolysis, rheumatoid-like small joint destruction, corneal opacities, and thickening and hypertrichosis of the skin, unlike that seen in other genodermatoses. The early stages of cutaneous abnormalities are characterized by proliferation of fibroblasts deep in the dermis, while hypocellular homogenization of the collagen is evident later. Ultrastructural peculiarities of fibroblasts include dilated and vacuolated mitochondria, the presence of varying amounts of myofilaments in the cytoplasm, and a prominent fibrous nuclear lamina.
