1. To identify specific mutations of MEN1 gen in the DNA of patients with proven or highly suspicious multiple endocrine neoplasia type 1 (MEN1).
2. To determine the molecular basis and extent of genotype-phenotype correlation of MEN1. At present, most unrelated MEN1 kindreds have unique mutations, suggesting that few mutation "hotspots" exist in the MEN1 gene. This study will identify the frequency of mutations by exon location as well as the prevalence of shared genotypes across kindreds.
3. To confirm or rule out the MEN1 diagnosis in patients with a component of the disease, but who do not fully meet the clinical diagnostic criteria for MEN1, thereby allowing for appropriate screening and treatment of all involved endocrine systems in the patient and facilitating genetic screening in their at-risk relatives.
4. To identify specific mutations of the MEN1 gene in the DNA of members of families with known MEN1 mutations. |
