Abstract
PURPOSE To report the efficacy of the oral hypoxia-inducible factor 2α inhibitor belzutifan in participants with von Hippel-Lindau disease-associated retinal hemangioblastomas in the LITESPARK-004 study. DESIGN Subgroup analysis of the phase 2, single-arm, open-label LITESPARK-004 study. PARTICIPANTS Adults with 1 or more von Hippel-Lindau disease-associated measurable renal cell carcinoma tumors not requiring immediate surgical intervention were eligible. METHODS Participants received oral belzutifan 120 mg once daily until disease progression or unacceptable treatment-related toxicity. MAIN OUTCOME MEASURES Efficacy of belzutifan in retinal hemangioblastomas was a secondary end point, measured as response (improved, stable, or progressed) by independent reading center-certified graders based on color fundus imaging performed every 12 weeks using the investigator's preferred imaging standards. Additional assessments, where available, included OCT and ultra-widefield fluorescein angiography. RESULTS Among 61 participants in LITESPARK-004, 12 had 1 or more evaluable active retinal hemangioblastomas in 16 eyes at baseline per independent reading center. As of April 1, 2022, the median follow-up for participants with ocular von Hippel-Lindau disease at baseline was 37.3 months. All 16 eyes were graded as improved, with a response rate of 100.0% (95% confidence interval, 79.4%-100%). No new retinal hemangioblastomas or ocular disease progression were reported as of data cutoff date. Eight participants underwent additional multimodal eye assessments performed at the National Institutes of Health study site. Among this subgroup, 10 of 24 hemangioblastomas in 8 eyes of 6 participants measured 500 μm or more in greatest linear dimension at baseline and were analyzed further. All 10 hemangioblastomas had a mean area reduction of 15% or more by month 12 and of 30% or more by month 24. CONCLUSIONS Belzutifan showed promising activity against ocular von Hippel-Lindau disease, including capacity to control retinal hemangioblastomas, with effects sustained for more than 2 years while treatment is ongoing.

Abstract
Von Hippel–Lindau disease (VHL) is a rare hereditary disease characterized by the predisposal to develop different types of highly vascularized tumors. VHL patients carry a VHL mutation that causes partial lack of functional VHL protein (pVHL) in all cells, and a total lack thereof in cells harboring a second hit mutation. Absence of pVHL generates a prolonged state of pseudo-hypoxia in the cell due to accumulation of hypoxia inducible factor, an important transcription factor regulating pro-tumorigenic genes. The work here presented focuses on characterizing the endothelium of VHL patients, by means of blood outgrowth endothelial cells (BOECs). Transcriptome analysis of VHL-derived BOECs, further supported by in vitro assays, shows that these cells are at a disadvantage, as evidenced by loss of cell adhesion capacity, angiogenesis defects, and immune response and oxidative metabolic gene downregulation, which induce oxidative stress. These results suggest that the endothelium of VHL patients is functionally compromised and more susceptible to tumor development. These findings contribute to shedding light on the vascular landscape of VHL patients preceding the second hit mutation in the VHL gene. This knowledge could be useful in searching for new therapies for these patients and other vascular diseases.

Abstract
Importance Asymmetric retinitis pigmentosa (RP) is a rare presentation of a normally symmetric condition. Histopathologic evidence should be examined to see if this asymmetry extends to the tissue and cellular levels. Objective To determine whether additional information can be obtained about asymmetric RP from studying clinical imaging and pathology correlates, including pathology samples from autopsied eyes. Design, Setting, and Participants In this case report, clinical and postmortem histopathological characteristics were compared in 2 eyes of a patient in her 50s with asymmetric RP. Individuals with rare mendelian diseases, such as RP, were studied using data from the curated National Eye Institute Eye Pathology collection. Main Outcome and Measures Results of clinical evaluation, multimodal retinal imaging, histopathology, and molecular genetic testing in a case of nonsyndromic asymmetric RP using resources from the ocular pathology collection. Results Eyes from a deceased patient in her 50s with nonsyndromic asymmetric RP found within the ocular pathology collection were studied. The patient was diagnosed with RP as an adolescent and presented in her 50s to the eye clinic with advanced RP, with the left eye affected much more severely than the right. The patient's phenotype was studied using in vivo imaging and postmortem histopathology to identify interocular differences in tissue degeneration. Extraction of blood-derived DNA and formalin-fixed paraffin-embedded DNA from autopsied eyes analyzed using next-generation sequencing did not yield a definitive molecular diagnosis nor significant tissue differences. Conclusions and Relevance This study demonstrates newly reported histopathological and molecular correlates in asymmetric RP. This report also highlights the relevance of studying previously seen patients and reevaluating their conditions using resources within the ocular pathology collection to gain further insight on their disease.

Abstract
OBJECTIVE Von Hippel-Lindau (VHL) syndrome is a rare disease that occurs in an autosomal-dominant genetic pattern. Due to the high genetic variability of VHL diseases, current studies have limited clinical value. Moreover, casual genetic variations in patients with VHL syndrome are still unclear. METHODS Here, we performed whole-exome sequencing of 25 individuals to identify reliable disease-related variations. Systemic computational analysis was performed for variant detection, and Sanger sequencing was used to validate detected mutations. RESULTS Most of the known mutations in the VHL gene were observed in the studied population. In addition, a large fragment deletion in VHL exon 2 in the immediate family members of the last family was detected. This had not been reported earlier. Moreover, we identified 3 novel mutation sites in the MAP2K3 gene that may be involved in the occurrence and development of the VHL disease. CONCLUSIONS These results demonstrated that the heterogeneous nature of VHL syndrome and novel mutational signatures may help to improve the diagnostic ability of VHL syndrome.

Abstract
BACKGROUND Von Hippel-Lindau (VHL) disease is an autosomal dominant genetic tumour syndrome resulting from mutations in the VHL gene lineage, and its prognosis is generally poor. This study aimed to provide a more valuable genotype-phenotype correlation based on the Elongin C binding site in VHL disease. METHODS This study included 553 patients (194 families) who were diagnosed with VHL disease in our centre from September 2010 to February 2019. According to the type of gene mutation, the patients were divided into the Elongin C binding site missense mutation (EM) group, the non-Elongin C binding site missense mutation (nEM) group and the truncation mutation (TR) group. We analysed and compared the age-related tumour risk and prognosis of the three groups. RESULTS A total of 14 new intragenic mutations were found in this cohort. The age-related risk of central nervous system haemangioblastoma (CHB) and pancreatic tumour in the EM group was lower than in the combined nEM-TR group, while the corresponding risk of pheochromocytoma (PHEO) was higher. Additionally, the prognoses of EM and nEM-TR were analysed. The median survival period in the EM group was longer than that in the nEM-TR group, and both the total survival and the CHB-specific survival of the EM group were better than those of the nEM-TR group. CONCLUSION In conclusion, our study demonstrated that the EM was an independent risk factor for PHEO. The EM is also an independent protective factor for CHB age-related risk, overall survival and CHB-specific survival in VHL disease. This modified genotype-phenotype correlation integrates gene mutation, the Elongin B binding site, and phenotypic diversity and provides a reference for clinical diagnosis.

Abstract
PURPOSE Von Hippel-Lindau (VHL) disease is a hereditary disorder that can lead to ophthalmic manifestations, including retinal capillary hemangioma (RCH). The diagnosis of RCH is often guided by wide-field fluorescein angiography. In some cases, optical coherence tomography angiography (OCT-A) serves as a non-invasive alternative to FA. Herein, we used OCT-A to examine the macular microvasculature in patients with VHL disease. SUBJECTS Subjects were selected from patients with a diagnosis of VHL. The control group included eyes without retinal diagnosis from patients with an episode of unilateral retinal detachment or trauma and age ≤ 50 years old. METHODS Subjects were scanned on the Optovue RTVue-XR device to acquire 3mm x 3mm OCT-A images of the superficial (SCP) and deep capillary plexus (DCP). SCP and DCP vessel density (VD) were calculated after the images were binarized. Furthermore, for subjects with RCH, each OCT-A image was divided equally into four quadrants. SCP and DCP VD of quadrants with RCH were compared to those without RCH. T-tests were performed for statistical analysis. RESULTS 67 eyes with a history of VHL disease were included as study subjects, while 16 eyes were included as controls. Significant increases in VD were found in patients with VHL disease for both the SCP (p = 0.0441) and DCP (p = 0.0344). When comparing quadrants with associated RCH development to those without, we found no significant difference in SCP VD (p = 0.160) or DCP VD (p = 0.484). CONCLUSIONS OCT-A can detect changes in the retinal microvasculature in the macula of patients with VHL disease. OCT-A imaging may be an additional tool for screening and early detection of patients at risk of developing ocular complications of VHL disease. Future studies should explore subtle progression on OCT-A associated with the pathogenesis and development of RCH, particularly with larger scan patterns.

Abstract
Pheochromocytomas and paragangliomas (PPGLs) are rare neuroendocrine tumors originating from chromaffin cells in the adrenal medulla (PCCs) or extra-adrenal sympathetic or parasympathetic paraganglia (PGLs). About 40% of PPGLs result from germline mutations and therefore they are highly inheritable. Although dysfunction of any one of a panel of more than 20 genes can lead to PPGLs, mutations in genes involved in the VHL/HIF axis including PHD, VHL, HIF-2A (EPAS1), and SDHx are more frequently found in PPGLs. Multiple lines of evidence indicate that pseudohypoxia plays a crucial role in the tumorigenesis of PPGLs, and therefore PPGLs are also known as metabolic diseases. However, the interplay between VHL/HIF-mediated pseudohypoxia and metabolic disorder in PPGLs cells is not well-defined. In this review, we will first discuss the VHL/HIF axis and genetic alterations in this axis. Then, we will dissect the underlying mechanisms in VHL/HIF axis-driven PPGL pathogenesis, with special attention paid to the interplay between the VHL/HIF axis and cancer cell metabolism. Finally, we will summarize the currently available compounds/drugs targeting this axis which could be potentially used as PPGLs treatment, as well as their underlying pharmacological mechanisms. The overall goal of this review is to better understand the role of VHL/HIF axis in PPGLs development, to establish more accurate tools in PPGLs diagnosis, and to pave the road toward efficacious therapeutics against metastatic PPGLs.

Abstract
Von Hippel-Lindau (Vhl) protein inhibits hypoxia-inducible factor (Hif), yet its deletion in murine retina does not cause the extensive angiogenesis expected with Hif induction. The mechanism is unclear. Here we show that retinoblastoma tumor suppressor (Rb1) constrains expression of Hif target genes in the Vhl-/- retina. Deleting Rb1 induced extensive retinal neovascularization and autophagic ablation of photoreceptors in the Vhl-/- retina. RNA-sequencing, ChIP, and reporter assays showed Rb1 recruitment to and repression of certain Hif target genes. Activating Rb1 by deleting cyclin D1 induced a partial defect in the retinal superficial vascular plexus. Unexpectedly, removing Vhl suppressed retinoblastoma formation in murine Rb1/Rbl1-deficient retina but generated subretinal vascular growths resembling retinal angiomatous proliferation (RAP) and retinal capillary hemangioblastoma (RCH). Most stromal cells in the RAP/RCH-like lesions were Sox9+, suggesting a Müller glia origin, and expressed Lgals3, a marker of human brain hemangioblastoma. Thus, the Rb family limit Hif target gene expression in the Vhl-/- retina, and removing this inhibitory signal generates new models for RAP and RCH.

Abstract
AIMS To investigate the association of peripheral retinal non-perfusion with retinal haemangioblastoma. METHODS Medical and widefield fluorescein angiography records of patients diagnosed with retinal haemangioblastoma from 1990 to 2018 were reviewed for patient demographics, tumour features, fluorescein angiography features and characteristics of peripheral retinal non-perfusion. RESULTS There were 41 eyes of 40 patients with retinal haemangioblastoma imaged by widefield fluorescein angiography during this time period. Of 41 eyes, 14 (34%) had haemangioblastoma-associated peripheral retinal non-perfusion on fluorescein angiography. A comparison of eyes with versus without non-perfusion revealed younger mean age at presentation (28 vs 43 years old, p=0.05), increased prevalence of von Hippel-Lindau (VHL) disease (62% vs 22%, p=0.01), greater mean largest tumour basal diameter (3.7 vs 2.5 mm, p=0.04), greater tumour distance from optic nerve (8.4 vs 1.9 mm, p<0.01) and increased prevalence of vascular leakage from the tumour (86% vs 52%, p=0.03). After mean follow-up of 97 versus 71 months (p=0.52), eyes with non-perfusion were significantly more likely to develop neovascularisation (40% vs 0%, p<0.01) and experience a three-line or greater decrease in visual acuity (60% vs 11%, p<0.01). CONCLUSION Peripheral retinal non-perfusion can be associated with retinal haemangioblastoma, and could be more common with larger, more peripheral tumours in younger patients with VHL disease. Eyes with haemangioblastoma-associated peripheral non-perfusion could be more likely to develop neovascularisation and lose visual acuity.

Abstract
Pheochromocytoma and paraganglioma (PCPGs) are rare neuroendocrine tumors that arise from the chromaffin tissue of adrenal medulla and sympathetic ganglia. Although metastatic PCPGs account for only 10% of clinical cases, morbidity and mortality are high because of the uncontrollable mass effect and catecholamine level generated by these tumors. Despite our expanding knowledge of PCPG genetics, the clinical options to effectively suppress PCPG progression remain limited. Several recent translational studies revealed that PCPGs with different molecular subtypes exhibit distinctive oncogenic pathways and spectrum of therapy resistance. This suggests that therapeutics can be adjusted based on the signature molecular and metabolic pathways of PCPGs. In this review, we summarized the latest findings on PCPG genetics, novel therapeutic targets, and perspectives for future personalized medicine.

Abstract
AbstractBackground:Central nervous system (CNS) hemangioblastoma (HB) is the most common tumor in the von Hippel Lindau (VHL) disorder, the hereditary tumor syndrome caused by the biallelic mutations of theVHLgene. The disrupted VHL and Elongin protein interaction on hypoxia-inducible factor-1α (HIF-1α) induces a set of hypoxia-inducible genes, resulting in an unchecked endothelial cell proliferation that then leads to hemangioblastoma formation. However, recent studies have shown that disruptive germline mutations ofVHLneed not result in hemangioblastoma, though it can cause other manifestations of the VHL syndrome. Similarly, sporadic hemangioblastoma can occur rarely without a somatic biallelicVHLmutation. The VHL protein was earlier found to be associated with the deposition of matrix fibronectin (FN) protein in the renal extracellular matrix.Methods:The present study was designed to investigate the deposition of the matrix FN protein in VHL-associated hemangioblastoma.Results:Seven HB tumor samples from the VHL syndrome had lower expressions of tissue FN compared to the control cerebellum samples or the control blood vessel sample. On comparing the VHL and FN protein expressions in a timed endothelial tube assay, the VHL protein expression was absent during the initial phase of tube formation but started expressing after 6 h. The levels of matrix form of FN gradually increased along with the VHL expression during the maturation of tube formation. Tube formation was found to be enhanced with extraneously added soluble FN and inhibited by matrix FN. Similarly, tube formation was inhibited by a modified tripeptide (RGD) inhibitor of integrin (-αVβ3), namely, Cyclo-Ala-Arg-Gly-Asp-3-aminomethylbenzoyl.Conclusions:Our study implicates that the extracellular deposition and matrix formation of FN is important for vascular endothelial proliferation, and that its absence has roles in the development of hemangioblastoma in the VHL syndrome.

Abstract
Background To describe a case of von Hippel-Lindau disease with peripheral retinal nonperfusion. Case presentation A 66-year-old female with known cerebellar and midbrain hemangioblastomas was evaluated for a retinal hemangioblastoma in the right eye. She underwent widefield fluorescein angiography, which showed hyperfluorescence localized to the hemangioblastoma surrounded by peripheral retinal nonperfusion in the same quadrant. Conclusions Further widefield imaging studies are required to determine if peripheral retinal nonperfusion is a common finding in von Hippel-Lindau disease.

Novel genotype-phenotype correlations in five Chinese families with Von Hippel-Lindau disease. Endocr Connect 2018; 7:870-878.

Abstract
CONTEXT Von Hippel-Lindau (VHL) disease manifests as a variety of benign and malignant neoplasms. Previous studies of VHL disease have documented several genotype-phenotype correlations; however, many such correlations are still unknown. Increased identification of new mutations and patients with previously described mutations will allow us to better understand how VHL mutations influence disease phenotypes. PATIENTS AND DESIGN A total of 45 individuals from five unrelated families were evaluated, of which 21 patients were either diagnosed with VHL disease or showed strong evidence related to this disease. We compared the patients' gene sequencing results with their medical records including CT or MRI scans, eye examinations and laboratory/pathological examinations. Patients were also interviewed to obtain information regarding their family history. RESULTS We identified four missense mutations: c.239G>T (p.Ser80Ile), linked with VHL Type 2B, was associated with renal cell carcinoma, pheochromocytoma and hemangioma in the cerebellum; c.232A>T (p.Asn78Tyr) manifested as RCC alone and likely caused VHL Type 1; c.500G>A (p.Arg167Gln) mutation was more likely to cause VHL Type 2 than Type 1 as it preferentially induced Pheo and HB in the retina, cerebellum and spinal cord; c.293A>G (p.Try98Cys) was associated with Pheo and thus likely induced VHL Type 2. CONCLUSIONS Characterizing VHL disease genotype-phenotype correlations can enhance the ability to predict the risk of individual patients developing different VHL-related phenotypes. Ultimately, such insight will improve the diagnostics, surveillance and treatment of VHL patients. PRECIS Four missense mutations in VHL have been identified in 21 individuals when five unrelated Chinese families with VHL disease were analyzed; VHL mutations are highly associated with unique disease phenotypes.
