When was vhl discovered

No significant difference in age-related risks of other symptoms was discovered among the three M subgroups. Figure 3. Finally, 87 of patients were diagnosed as type 2 VHL disease. Patients in M group with mutations in exon 2 vs. Table 4. The univariate and multivariate cox analyses of age-related risks of PCT.

The estimated median lifespan of all patients was 62 year. Missense mutations carriers seemed to have longer estimated median survival than others 63 vs. The estimated median survival of patients in NoF1 subgroup was 9 years longer than those in NoF2 subgroup 64 vs. Figure 4. Comparison of survival in patients with different mutation groups.

B Comparison of survival in type 1 and type 2 patients. A total of of patients had died of some causes, which were categorized as CHB related, RCC related, and other causes of death. A total of Their death age ranged from 11 to 71 with a median of The VHL disease is characterized by lifelong multiorgan and multisite tumors risks.

Genotype-phenotype correlations are crucial to clinical genetic counseling. Several previous studies have focused on genotype-phenotype correlations of the VHL disease, but there was still a lack of authoritative consensus Ong et al. In our study, type 1 patients were associated with higher lifetime risks of CHB and worse survival compared with type 2 patients.

Our study suggests that MO subgroup should be treated as a separate subgroup independent of ME and MH subgroup, and NoF1 subgroup should be seen as a separate subgroup with a relatively better prognosis independent of the N2TR subgroup. These discoveries have the potential to improve and detail clinical counseling of VHL disease and reveal the underlying molecular mechanisms.

The small number of people in MO subgroup and not long enough follow-up time limited more detailed genotype-phenotype research. It might explain this divergence that we defined the new MO subgroup from non-MH missense mutations carriers and we expanded the sample size. However, there is a lack of evidence at molecular levels to support the rationality of this classification method, which is mainly based on VHL-HIF pathway.

Mutations at different locations are likely to change the intrinsic structure and interfaces of the VHL protein Minervini et al. Further studies should classify mutations based on their effects on the structure and functions of the VHL protein rather than merely on the basis of mutation locations.

In our cohort, the estimated median lifespan of all patients is 62 year. For PCT, patients in M group with mutations in exon 2 vs. This conclusion is inconsistent with Tirosh et al.

In view of the divergences and uncertainties, more research is needed to explore the risk factors of PCT in VHL patients. At present, the main management measures of VHL disease are active surveillance and surgical intervention when necessary.

Clinicians need to weigh the risks of tumor progression and metastasis against the risks of surgical intervention and complication. There is a lack of scientific and authoritative surgical indications for each of five main symptoms to refer to. Existing standards often focus mainly on clinical parameters but ignore mutation types of patients. According to the current mainstream view, only symptomatic tumors need to be resected Dornbos et al.

Peng et al. For patients with a PNET diameter between 1. In the following studies, the VHL genotype should be taken into consideration to determine whether surgical treatments are needed or not, to predict the risk of tumor recurrence, progression, and metastasis, and to predict therapeutic effects of non-surgical interventions. The correlation tries to subgroup truncating mutations and missense mutations, predicting tumor penetrance and survival of VHL patients.

Our results will work as a VHL disease risk stratification method and provide more detailed information for genetic counseling. The studies involving human participants were reviewed and approved by the Institutional Ethics Committee of the Peking University First Hospital. Written informed consent to participate in this study was provided by all patients or their legal guardians.

Clifford, S. Czyzyk-Krzeska, M. Trends Mol. Dornbos, D. The only way to diagnose VHL is with genetic testing. There are no universal guidelines regarding who should be screened for VHL. However, VHL should be suspected when a person has:. If a person has a family history of VHL, they are suspected of also having VHL if the person has any 1 symptom, such as hemangioblastoma of the brain, spine, or eye, kidney cancer, pancreatic cysts, pheochromocytoma, or endolymphatic sac tumor.

Please note that this link takes you to a separate, independent website. In general, treatment for kidney cancer is similar regardless of whether a patient has VHL. However, there is some evidence about specific VHL considerations regarding surgery. For a person with VHL and kidney cancer, surgery for a kidney tumor is generally considered when the largest tumor reaches 3 centimeters cm in size.

This is generally done with enucleative resection, taking zero margins as the tumor capsule is separated from the surrounding adjaent parenchyma. Similarly, the main treatment for tumors arising in other organs is also surgery, which is done when the tumor reaches a specific size or causes symptoms.

Researchers are also actively investigating the use of systemic medications earlier in the disease stage when patients cannot have surgery. Belzutifan Welireg is a medication taken by mouth orally that targets hypoxia-inducible factor-2 alpha HIF2a. A recent study NCT included 61 people with VHL-associated tumors, mostly in the kidney, that did not need surgery right away. In this study, Screening for new tumors or active surveillance for known tumors are both very important aspects of VHL care.

If tumors are found early, there is a much better chance that treatment will be successful. There are clear recommendations on the frequency and type of screening that should be performed.

As VHL manifestations can vary, recommendations for a person's medical surveillance will change over their lifetime. These recommendations are expected to change over time as more information is made available and new technologies are developed specific to VHL.

It is important to talk with your health care team about appropriate screening tests.
