The use of polymorphic DNA segments as markers for the gene for the multiple endocrine neoplasia (MEN) syndrome, type 2a, allows the identification of family members at high risk for developing medullary carcinoma of the thyroid and other tumors, especially pheochromocytoma. Several families have also been identified in which medullary thyroid carcinoma is inherited, but pheochromocytoma is not seen. We have analysed 18 families, 9 with MEN 2A and 9 with medullary carcinoma of the thyroid without pheochromocytoma, with probes specific for the pericentromeric region of chromosome 10 and conclude that the mutations for the two presentations are closely situated. Genetic heterogeneity of the susceptibility locus was not seen among this sample of 18 families. The genetic mutation for medullary carcinoma was in disequilibrium with the marker alleles of the two closely linked probes, IRBPH4 and MCK2. These data suggest that different mutant alleles of the same gene or closely linked mutations account for the variation in penetrance of pheochromocytoma in families with hereditary medullary thyroid carcinoma.
