Description
VHL is a tumor suppressor gene involved in the oxygen-sensing pathway whose germline mutations predispose to distinct phenotypes. Heterozygous mutations predispose to von Hippel-Lindau disease characterized by the development of multiple tumors (including hemangioblastomas, renal cell carcinomas and pheochromocytomas)1-3. More recently, a specific VHL-R200W mutation was shown to be responsible for Chuvash Polycythemia in homozygous carriers whereas heterozygous individuals have no clinical manifestation4. We report here a family carrying, on the same allele, VHL mutations characteristics of the two types of disease (a Chuvash polycythemia-R200W mutation and a von Hippel-Lindau disease-R161Q mutation). Genotyping, modeling analysis and functional studies, including transcriptomic profile of the distinct mutants validated for the first time on direct HIF target genes, show a gradual capacity of the VHL mutants to regulate the hypoxia responsive pathway that correlate with the severity of the developed phenotype. Our study provide original results that illuminate genotype/phenotype correlations in von Hippel-Lindau disease.
