Frank-Ter Haar syndrome (FTHS), Winchester syndrome (WS), and multicentric osteolysis, nodulosis, and arthropathy (MONA) are ultra-rare multisystem disorders characterized by craniofacial malformations, reduced bone density, skeletal and cardiac anomalies, and dermal fibrosis. These autosomal recessive syndromes are caused by homozygous mutation or deletion of respectively SH3PXD2B (SH3 and PX Domains 2B), MMP14 (matrix metalloproteinase 14), or MMP2. Here, we give an overview of the clinical features of 63 previously reported patients with an SH3PXD2B, MMP14, or MMP2 mutation, demonstrating considerable clinical overlap between FTHS, WS, and MONA.

Torg-Winchester syndrome: lack of efficacy of pamidronate therapy.

Clin Dysmorphol 2007 Apr;16(2):95-100

Department of Medical Genetics, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, India Department of Human Genetics, Mount Sinai School of Medicine, New York, USA.

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

Department of Medical Genetics, Archet 2 Hospital, CHU Nice, France.

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

Winchester syndrome caused by a homozygous mutation affecting the active site of matrix metalloproteinase 2.

Clin Genet 2005 Mar;67(3):261-6

Division of Molecular Pediatrics, Center Hospitalier Universitaire Vaudois, CH-1011 Lausanne, Switzerland.

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.

Progressive multilayered banded skin in Winchester syndrome.

J Am Acad Dermatol 2004 Feb;50(2 Suppl):S53-6

Department of Dermatology (Hammersmith Hospitals Trust), Chelsea and Westminster Hospital, 369 Fulham Road, London SW10 9NH, UK.

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.

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

Unité de Génétique Médicale du CHU de Nice.

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

Familial vanishing limbs: four generations of idiopathic multicentric osteolysis.

Clin Radiol 1983 Sep;34(5):585-8

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.
