    1. Relative telomere length assessment Genomic DNA was isolated from peripheral blood by using a blood DNA extraction kit (Tiangene). We followed the method described by Cawthon to quantify relative telomere length by measuring copy number ratio of telomere repeats (T) to the single copy gene 36B4 (S) using qRT-PCR (24). The 10-μL PCR mixture contained 2X SYBR master mix (Takara) 5 μL, genomic DNA 30 ng, 300 nmol/L telomere primer Tel1 (5′-GGTTTTTGAGGGTGAGGGTGAGGGTGAGGGTGAGGGT) and 900 nmol/L Tel2 (5′-TCCCGACTATCCCTATCCCTATCCCTATCCCTATCCCTA), or 200 nmol/L single copy gene primer 36B4u (5′-CAGCAAGTGGGAAGGTGTAATCC), and 500 nmol/L 36B4d (5′-CCCATTCTATCATCAACGGGTACAA; ref. 19). qRT-PCR was run in an ABI 7500 PCR instrument using the profile of 95°C for 30 seconds and 40 cycles of 95°C for 15 seconds, 54°C for 2 minutes, and 72°C for 15 seconds. A standard curve from a control DNA sample (male, 45 years old) by serial 1/4 dilutions from 50 ng to 0.19 ng was constructed to evaluate the amplification efficiency (E), and this sample was measured in every batch of PCRs as the inter-run calibration. Threshold cycle (Ct) values were automatically determined by the 7500 software v2.0.5. The measurements of telomere length and single copy gene 36B4 were triplicate in one batch for each sample, and the mean of the three Ct values (Cm) was used for the calculation. PCR efficiency and the calibration of copy numbers were also enrolled in the telomere length calculation (19, 25). The formula to calculate the copy number ratio of telomere repeats (T) to single copy gene 36B4 (S) is as follows, and T/S represents the value of relative telomere length. <img class="highwire-embed" alt="Embedded Image" src="https://cancerres-aacrjournals-org.uhn.idm.oclc.org/sites/default/files/highwire/canres/74/14/3802/embed/graphic-1.gif"/> The relationship between age and relative telomere length in 325 normal controls can be expressed by the linear regression equation of Y = 1.4503-0.0117*X (see Fig. 2). Normal relative telomere length at the DNA sample-obtained age can then be predicted by this equation. The difference between predicted normal relative telomere length at the DNA-obtained age and the relative telomere length actually measured was the age-adjusted relative telomere length (19), which was used for the comparison among patients with VHL in generations. Telomere length measurement by Southern blot analysis The oligonucleotide (TTAGGG)4 was tailed with DIG-dUTP as the probe by using terminal transferase. Two micrograms of genomic DNA were digested with HinfI/RsaI and separated in 0.8% agarose gel. The DNA fragments in the gel were then transferred onto a Hybond-N membrane by Southern blotting. After UV cross-link and prehybridization, the membrane was hybridized in a solution containing 2 pmol/mL probe, 50% formamide, 2× SSC, 0.1% lauroyl sarcosine, 0.02% SDS, and 1% milk powder at 42°C for 6 hours, washed at room temperature in 2× SSC, 0.1% SDS for two times, and in 0.1× SSC, 0.1% SDS, 15 minutes for two times. Hybridized probe on the membrane was recognized by alkaline phosphatase conjugated anti-DIG antibody and chemiluminescent method. The luminescent image was developed on a phosphoimager. The telomere length was calculated by a telomeric software (version 1.2; ref. 26).
    1. (c.269A > T)

      A 35 year old woman was admitted with long-standing dyspepsia and pancreatic cysts. There were no other symptoms. The past medical and family histories were not of significance. Imaging studies showed the presence of multiple cysts in the head and tail of the pancreas suggesting pancreatic serous cystadenomas. Cysts were also found within the left kidney and spleen. MRI of the brain and entire spine found no hemangioblastomas and abdominal MRI scan excluded renal carcinoma. Pheochromocytoma, angiomas of the retina and endolymphatic sac tumors were also excluded. Genetic testing revealed a germline missense mutation N90I (c.269A>T) in the VHL gene. This variant was also found in her 7 year old daughter. Phenotypic information for the daughter was not described. Authors state this variant as being likely de novo in the proband.

    1. Patient II‐1 was admitted to the Department of Urinary Surgery and Neurosurgery in October 2007 and again in December 2015. In the first hospitalization, a serendipitous left kidney mass was found, but no symptoms. Abdominal CT revealed a solid cystic mass on the inside of the left kidney with irregular enhancement (Figure ​(Figure2b),2b), indicating a radiological diagnosis of RCCC. A laparoscopic radical nephrectomy was performed, and pathology confirmed the diagnosis of clear cell carcinoma. In the second hospitalization, the patient was admitted with complaints of headache and dizziness for 2 months. A brain MRI showed a right CH (Figure ​(Figure2c).2c). Tumor resection was performed through a posterior approach, and pathology confirmed the diagnosis of hemangioblastoma. In the most recent follow‐up, his symptoms had disappeared, and radiological imaging revealed no recurrence in either the brain or abdomen.

    2. The proband (Patient III‐1) was admitted into our ward in October 2015 with a complaint of an occipital headache for 1 month. He was conscious, and a physical examination did not reveal ataxia. Tests for cranial nerve function, limb sensation and motor function were unremarkable. Contrast‐enhanced brain magnetic resonance imaging (MRI) revealed a solid‐cystic mass in the vermis cerebelli and left cerebellar hemisphere (Figure ​(Figure2a),2a), indicating a radiological diagnosis of CH. Cerebellar tumor resection was performed through a sub‐occipital craniotomy under general anesthesia, and the tumor was completely removed. The tumor, which was 30 mm in diameter, was pink and soft and composed of dilated veins and dense blood capillaries. A postoperative pathological analysis of the tumor indicated a hemangioblastoma. The patient completed outpatient follow‐up in October 2018. The occipital headache had disappeared, brain MRI showed no recurrence, and abdominal computerized tomography (CT) revealed no neoplasms.

      During the period from 2009 to 2012, 39 families with VHL disease were diagnosed with hereditary VHL disease at Peking University First Hospital Department of Urology were described as part of a broader study examining telomere length and anticipation. In these families, 19 families had two or more than two patients in two or more than two generations, including one family with obscure onset age. Therefore, a total of 57 patients with VHL disease from 18 families were enrolled in this study. Using peripheral blood and southern blotting, DNA sequencing was completed on the following patients. Family 4 involved three affected members, however only two of which were known to have a c.269A>T change leading to a p.Asn90Ile protein change. The male proband presented with hemangioblastoma at 22 and retinal capillary hemangioma at 32. His mother presented with renal cell carcinoma at 63. The proband’s brother died before diagnosis; thus no DNA sample available, however he was affected with hemangioblastoma at age 19Y. Of family 9, the male proband presented with hemangioblastoma at 28, renal cell carcinoma at 38, and pancreatic cysts at 38. His mother, aunt and cousin all died before diagnosis; thus no DNA sample available. The mother was last observed at 33Y with CNS hemangioblastoma; the aunt at 32Y with hemangioblastoma, and the cousin at 30Y with hemangioblastoma. ACMG Evidence Code: 'PP4' because the patients' phenotypes and family histories are highly specific for VHL disease.

    1. c.269A > T p.Asn90Ile

      216 patients with clinically expected VHL disease due to family history or presence of VHL typical tumours were routinely examined in an eye centre in Germany between January 2019 and January 2020, majority of which were of European descent (~95%). Since data on the genotype–phenotype correlation of the onset of Retinal Hemangioblastoma (RH) is scarce in relation to VHL disease, this study wanted to inversitage the relationship between VHL gene variants (truncating vs single amino acid substitutions) and the ocular phenotype of the disease. 42 different rare VHL gene variants in 148 patients were detected - some of whom had RH and some who did not. Although date of onset of RH, as well as data on central nervous system haemangioblastomas (CNSH), pheochromocytoma/paraganglioma (PPGL), clear cell renalcell carcinoma (ccRCC) and pancreatic neuroendocrine neoplasm (PNEN) were collected, it was not reported on a per patient basis and therefore could not be discussed per variant. There was 1 patient reported with the c.269A>T (p.N90I) mutation. This member presented with retinal hemangiomas. No family information was provided.

    1. This case concerns a 35-year-old woman referred to our Gastroenterology Department with long-standing dyspepsia and pancreatic cysts detected by ultrasound examination. There were no other symptoms, such as abdominal pain, weight loss, visual or hearing changes, headache or urinary complaints. The past medical and family histories were not of significance. There were no abnormal findings on examination.The patient underwent an abdominal computed tomography (CT) scan (Figure ​(Figure1),1), which showed an enlargement of the pancreas, especially in the cephalic region, with heterogeneous density due to the presence of multiple hypodense nodules dispersed throughout the parenchyma. The majority of these lesions were small, but one larger contrast-enhancing lesion of 22 mm was present in the uncinate process.Open in a separate windowFigure 1Computed tomography abdominal scan. A: Small cystic lesions dispersed throughout the pancreas; B: The largest lesion.Given the findings of the CT scan, we performed an abdominal magnetic resonance imaging (MRI) (Figure ​(Figure2),2), which revealed several cysts that had a high signal intensity on T2 weighted images.Open in a separate windowFigure 2Magnetic resonance imaging. Cyst lesions are bright on T2-weighted images.The patient underwent endosonography that confirmed the presence of multiple simple cysts throughout the entirety of the pancreas. The majority of the cysts were less than 1 cm in diameter, but two cysts were larger than 1 cm. One of the larger cysts was 16 mm in diameter and was located at the isthmus-body transition. This cyst and did not communicate with the main pancreatic duct and was aspirated. The content had a serous appearance, and cytological analysis revealed amorphous material, few erythrocytes and inflammatory cells (Figure ​(Figure33).Open in a separate windowFigure 3Endosonography. A, B show a large cyst of 16 mm in diameter without communication or dilatation of the pancreatic duct; C: Demonstrates aspiration of the cyst; D: Demonstrates its appearance after total aspiration.The largest cyst was 23 mm in diameter and was located in the head of the pancreas. The cyst had a honeycomb appearance characteristic of serous cystadenomas (Figure ​(Figure4A).4A). The cytology did not show evidence of cellular atypia (Figure ​(Figure4B).4B). The carninoembryonic antigen was < 0.6 ng/dL, and the amylase in the cystic content was 135 U/L.Open in a separate windowFigure 4The largest cyst was 23 mm in diameter and was located in the head of the pancreas. A: Endosonography. Cyst with a honeycomb appearance; B: Cytology (papanicolaou stain, × 100). Benign pancreatic cysts.The endosonography also showed cysts in the left kidney and in the spleen (Figure ​(Figure5).5). The findings described were compatible with simple cysts and pancreatic serous cystadenomas and provided an indication for genetic testing for VHL. The sequencing of the VHL gene revealed one pathogenic heterozygous mutation in exon 1 (c.269A > T), confirming the diagnosis of VHL disease.Open in a separate windowFigure 5Endosonography. A: A cyst in the renal cortex; B: A cyst in the spleen.The patient underwent a MRI of the brain and entire spine and no hemangioblastomas were detected. The abdominal MRI scan excluded renal carcinoma. The plasma and urinary catecholamines and the urinary vanilmandelic acid were normal, excluding pheocromocytoma. The patient was also referred for examination of the retina and ear, nose and throat, including audiometry. There were no abnormal findings, which excluded angiomas of the retina and endolymphatic sac tumors, respectively.
