Case: M, Age Unknown, German

DiseaseAssertion: Asymptomatic

FamilyInfo: The patient's father (patient 8) was had both mutations and presented with pheochromocytoma. The patient's brother (patient 10) did not carry the mutation and was unaffected. The patient's maternal grandfather (patient 3) presented with pheochromocytoma and carried both mutations. The patient's materal grandmother (patient 4) was unaffected and did not carry either mutation. The patient's great aunt (patient 2) presented with pheochromocytoma and had both mutations. Her husband (patient 1) was unaffected and did not carry either mutation. They had four children; one died and presented with pheochromocytoma, two (patient 5 and 7) had both mutations and presented with pheochromocytoma, and one child (patient 6) was unaffected and carried neither mutation. Patient 7 had a child (patient 9) who also carried both mutations and presented with pheochromocytoma. See Figure 3 for family pedigree.

FamilyInfo: The patient's father (patient 1) was unaffected and did not carry the mutation. The patient's mother (patient 2) presented with pheochromocytoma and carried the mutation. The patient had three siblings; one died and was affected, another (patient 5) had both mutations and presented with pheochromocytoma, and the third (patient 6) was unaffected and carried neither mutation. This patient (patient 7) had a child (patient 9) who also carried both mutations and presented with pheochromocytoma. The patient's uncle (patient 3) carried the mutation and was affected. He had a child with patient (4) who was unaffected. Their child (patient 8) carried both mutations and presented with pheochromocytoma. Patient 8 had two children; one that did not carry the mutation and was unaffected (patient 10) and another that carried both mutations but was disease free (patient 11).
