Protein Effect | unknown |
Gene Variant Descriptions | VHL L169P does not lie within any known functional domains of the Vhl protein (UniProt.org). L169P retains the ability to degrade Hif1a and results in hypoxia regulation and protein stability similar to wild-type Vhl in culture in one study (PMID: 37069149), but results in a HIF-dependent growth defect similar to VHL loss in a high-throughput cell culture assay in another study (PMID: 38969834), and therefore, its effect on Vhl protein function is unknown. |

VHL mutant | islet cell tumor | sensitive | Belzutifan | Guideline | Actionable | Welireg (belzutifan) is included in guidelines for patients with well-differentiated Grade 1/2 progressive pancreatic neuroendocrine tumors harboring germline VHL mutations (NCCN.org). | detail... |
VHL mutant | renal cell carcinoma | sensitive | Everolimus | Phase I | Actionable | In a Phase I study, Afinitor (everolimus), as compared to Apitolisib (GDC-0980), resulted in a greater progression free survival and overall survival in patients with renal cell carcinoma harboring VHL mutations (J Clin Oncol 32:5s, 2014 (suppl; abstr 4525)). | detail... |
VHL mutant | renal cell carcinoma | predicted - sensitive | Sunitinib | Phase I | Actionable | In a Phase I trial, 33% (6/18) of renal cell carcinoma patients harboring a VHL mutation, as determined from archived patient specimens, demonstrated a partial response when treated with Sutent (sunitinib) (PMID: 22105611). | 22105611 |
VHL mutant | renal cell carcinoma | no benefit | Unspecified VEGFR inhibitor | Clinical Study - Meta-analysis | Actionable | In a meta-analysis of 6 clinical studies, VHL mutation status was not associated with overall response rate (relative risk=1.47, p=0.20), progression-free survival (HR=1.02, p=0.91), or overall survival (HR=0.80, p=0.21) in a total of 633 patients with renal cell carcinoma who received anti-VEGF therapies (PMID: 28103578). | 28103578 |
