Primary Outcome Measures:
- Genetic risk factor for oral clefts
In a collaborative effort with the IBN AL-NAFEES Hospital (Damascus, Syrian Arab Republic), individuals from multiplex families determined to have hereditary oral clefts will be studied. The purpose of this study is to identify the gene(s) involved in heritable oral clefts by linkage analysis and gene mapping strategies. Characterization of genes involved in inherited oral clefts could provide important insight into the inheritance and pathogenesis of this disease.
