Case: F, Age Unknown, German

DiseaseAssertion: VHL

FamilyInfo: This patient and her unaffected spouse (patient 1) had four children; one died and was affected, 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. Furthermore, this patient's brother (patient 3) carried both mutations and presented with pheochromocytoma. 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). See Figure 3 for family pedigree.

GroupHPOFreeText: All 9 patients had pheochromocytoma, 2 of the 9 patients (unspecified) also had thyroid C-cell tumors, 1 (unspecified) had medullary thyroid carcinoma, and 1 (unspecified) had C-cell hyperplasia. 3 of the 9 patients (unspecified) also developed extra-adrenal pheochromocytoma.
