Since no pathogenic mutations were detected in the von Hippel-Lindau (VHL) gene, we can rule out that VHL deficiency is causing the general reduction of OXPHOS enzymes observed in the PCs investigated.

Pheochromocytomas are rare catecholamine-producing tumors derived in more than 30% of cases from mutations in 9 tumor-susceptibility genes identified to date, including von Hippel-Lindau tumor suppressor (VHL); succinate dehydrogenase complex, subunit B, iron sulfur (Ip) (SDHB); and succinate dehydrogenase complex, subunit D, integral membrane protein (SDHD).

The same VHL mutation has been reported in a patient who developed a pheochromocytoma at the age of 10 years; therefore, for known VHL Q164R mutation carriers, we suggest screening for pheochromocytoma beginning at 2 years of age.
