We performed a prospective genotype-phenotype study using molecular screening and clinical assessment to compare the severity of disease and the risk of sarcoma in 172 individuals (78 families) with hereditary multiple exostoses. We calculated the severity of disease including stature, number of exostoses, number of surgical procedures that were necessary,(More)
Hereditary multiple exostoses (HME), the most frequent of all skeletal dysplasias, is an autosomal dominant disorder characterized by the presence of multiple exostoses localized mainly at the end of long bones. HME is genetically heterogeneous, with at least three loci, on 8q24.1 (EXT1), 11p11-p13 (EXT2), and 19p (EXT3). Both the EXT1 and EXT2 genes have(More)
Endoprosthetic replacement of the pelvis is one of the most challenging types of limb-salvage surgery, with a high rate of complications. In an attempt to reduce this and build greater versatility into the reconstruction process, a new type of pelvic endoprosthesis was developed in 2003, based on the old McKee-Farrar prosthesis. This study reviews the(More)
EXT1 and EXT2 are two genes responsible for the majority of cases of hereditary multiple exostoses (HME), a dominantly inherited bone disorder. In order to develop an efficient screening strategy for mutations in these genes, we performed two independent blind screens of EXT1 and EXT2 in 34 unrelated patients with HME, using denaturing high-performance(More)
Hereditary multiple exostoses (HME) is traditionally described as a skeletal dysplasia. However, the discovery that the EXT family of tumour suppressor genes are responsible for HME suggests that it is more appropriate to classify HME as a familial neoplastic trait. In a clinical and radiographic analysis of paired bone length and exostoses number and(More)
Eight breast cancer pedigrees with a high probability of containing individuals with the BRCA1 gene mutation (odds 79.2-99.9 per cent) were identified through genetic linkage analysis using probes located within q12-22 on the long arm of chromosome 17. Some 102 female relatives were successfully typed with one or both of adjacent markers D17S588 and(More)
Familial clustering of breast cancer has been recognised for over a century but until recently a genetic basis has been suspected rather than proven. Epidemiological studies have tended to support the view that an autosomal dominant gene, with high but incomplete penetrance, accounts for most breast cancer families. However, it is likely that several(More)
PURPOSE Intramedullary (IM) nailing and plating are recognised fixation methods for both-bone midshaft forearm fractures. Although both methods are effective, IM nailing has recently been the accepted operative treatment for the paediatric population. The aim of the study was to compare the differences in the radiographic and functional outcomes of an age-(More)
We studied the pedigrees of 17 index patients with osteosarcoma, recording malignant disease and cause of death for first- and second-degree relatives. There were seven cancers and five cancer deaths per 2151.5 person-years in first-degree relatives of osteosarcoma patients under the age of 50 years, a significantly greater incidence than in an age- and(More)
HYPOTHESIS Patients with hereditary multiple exostoses (HME) in association with palpable shoulder exostoses are more severely affected by their disease. MATERIALS AND METHODS From a prospective database of 78 families with HME identified, 172 patients were identified. Demographic details, deformity, functional scores, standing height, number of(More)
