NCT00474331

Brief Summary

The investigator's goal for this project is to examine the causes of the wide variability of the expression of Hereditary Multiple Exostoses (HME). Previous work completed by our group shows that there exists a correlation between genotype and phenotype such that certain mutations or affected genes cause certain patterns of presentation, symptoms, and signs. The investigators intend to achieve this goal by increasing our study sample size to build upon the results generated from the pilot project of this study, in order to obtain statistical significance. This will be achieved by performing genotype-phenotype analysis on new families presenting with HME in British Columbia.
