      Case: M, Age Unknown, Mexican

      DiseaseAssertion: Asymptomatic

      FamilyInfo: Family composed of six affected individuals and three diseased subjects (III-2, III-3, III-4) were studied. III-4 (proband) presented with a CNS hemangioblastoma and a retinal hemangioblastoma. The mother (II-1) developed cerebellar, medullar and bilateral retinal HBs; two maternal aunts (II-2 and II-3) were affected by retinal and CNS HBs and unspecified renal tumors, whereas his grandfather (I-2) had unspecified abdominal tumors. All these relatives died in their early 30s. A 35-year-old sister (III-2) demonstrated cerebellar HB, right eye retinal HB and renal cell carcinoma, whereas a 32-year-old brother (III-3) presented with cerebellar HB, right eye retinal HB, renal cell carcinoma and pheochromocytoma. A mutation-carrier nephew (IV-2) presented only atrophy of the retinal pigment epithelium. All of these family members were found to have the R82P (c.245G>C) germline VHL variant. Eighteen additional healthy relatives were analyzed and tested negative for the mutation.

      CohortInfo: Two families and one apparently non-familial case were studied at the Institute of Ophthalmology ‘Conde de Valenciana’ (Mexico City, Mexico).

    1. A 3 year-old girl was admitted in the Department of Pediatric Oncology following several months history of febrile episodes, sweating and irritability. Symptoms were first interpreted as being of infectious causes, and that is why she received repeated antibiotic therapies. There was no improvement, and that is why more investigations were performed. An abdominal ultrasound performed in a pediatric hospital revealed a right adrenal tumor mass that prompted the transfer to our unit.Family history: the patient’s mother aged 38 was diagnosed with bilateral pheochromocytoma resected when she was the age of 18 years. She presented several relapses, the most recent one at the age of 32, when she was also diagnosed with cerebral angioma. Genetic testing revealed the presence of the VHL c 244 C>G (p. Arg 82 Gly) heterozygote mutation, while the tests for RET, SDHB, SDHC and SDHD were negative.The clinical examination of our patient revealed: pallor, paroxysmal febrile episodes with irritability and sweating, tachycardia (130/min), hypertension (170/126 mmHg). There was no palpable abdominal mass.Abdominal ultrasound: well delimited tumor of the right adrenal gland, 37/34/35 mm in diameter, irregular with transonic inclusions.Magnetic resonance imaging (MRI): right adrenal tumor, 35/42/43 mm in diameter, well delimited, irregular, with marked heterogenous contrast intake, presenting cystic and necrotic areas (Figure 1).Open in a separate windowFigure 1Right adrenal tumor.Serum markers: urinary vanillylmandelic acid (VMA) 31.1 mg/24 h (normal <6.6), neuron specific enolase (NSE) 59.79 ng/ml (normal <17), ferritin 306.6 ng/ml (normal range 6–67), lactic dehydrogenase (LDH) 333 IU/L (normal range 125–300).Genetic examination: VHL c 244 C>G (p. Arg 82 Gly) heterozygotic mutation.Management: Complete surgical resection was performed with special precautions, but it was uneventful and blood pressure instantly dropped to normal.Go to:PathologyMacroscopic encapsuled 40/40/30 mm tumor, delimited by a bright yellow rim. The tumor is nodular with small hemorrhagic and necrotic areas.Microscopy: adrenal gland is compressed by a well delimited tumor made by cell nests of variable dimensions, separated by a reduced vascular connective stroma (Zellballen), with relatively numerous mitoses (8/10 High Power Field - HPF), most of them typical, very few atypical, extensive necrosis and vascular invasion. The aspect is suggestive for a malignant pheochromocytoma with Pheochromocytoma of the Adrenal gland Scaled Score (PASS) score 7: vascular invasion (1), necrosis (2), mitoses (2) (Figure 2).Open in a separate windowFigure 2Example of light microscopy image of sections from the excised tumor showing characteristics of malignant pheochromocytoma (Zellballen with central necrosis), hematoxylin eosin (HE) stain (10X).Go to:OutcomeAfter 6 months of follow-up, the patient is without any clinical symptoms, with normal blood pressure, no tumor markers, no evidence of tumor on cerebral and abdominal MRI and a normal ophthalmoscopy.

      FamilyInfo: The patient’s mother and two brothers had died with cerebellar hemangioblastoma, although genetic testing was not performed. One of the patient’s four children, a 46Y male, also presented with a small renal tumour, renal cysts, and pancreatic cysts; he was found to carry the same mutation the patient carried. One of the patient’s grandsons, a 10Y male, was also found to carry the same mutation as the patient but was asymptomatic. Genealogical inquiry also revealed that the patient was distantly related to a known VHL family; one member, a 47Y male, was previously operated on for CNS hemangioblastoma, RCC and symptomatic pheochromocytoma and was found to carry the same mutation as the proband. Another female member had previously presented with retinal hemangioblastoma before becoming deceased at 37Y. The paper also asserted that the patient’s grandmother and two distant relatives carried the mutation, although genotyping was not performed and phenotypic information was not provided.

      CaseHPOFreeText: The patient was originally diagnosed with metastatic bilateral clear cell renal cell carcinoma at 68Y and underwent chemotherapy for three months. The metastases were later reinterpreted to be a cystic hemangioblastoma and a benign serous cystadenoma. The patient was also found to have a non-secreting adrenal pheochromocytoma at 73Y and a clear cell renal cell carcinoma metastasis in the thyroid at 74Y. The patient had also previously presented with retinal lesions, although detailed records were unavailable.

    1. The proband (III-4) was a 28-year-old male who consulted because of a history of VHL disease in his family. The mother (II-1) developed cerebellar, medullar and bilateral retinal HBs; two maternal aunts (II-2 and II-3) were affected by retinal and CNS HBs and unspecified renal tumours, whereas his grandfather (I-2) had unspecified abdominal tumours. All these relatives died in their early 30s (Table 1). Magnetic resonance (MR) imaging of brain and spine was performed in this subject demonstrating cerebellar HB. Ophthalmologic examination revealed VA of 6/6 in both eyes, and IOP of 14 mmHg in the right eye and of 18 mmHg in the left eye. No anomalies were found at biomicroscopic inspection; funduscopic evaluation of the right eye showed a well defined orange-red mass corresponding to a peripheral retinal HB of approximately 1 disc diameter associated with a prominent feeding artery and to a draining vein. FAG demonstrated hyperfluorescence of this retinal angioma as well as enlargement and tortuosity of retinal blood vessels.

      FamilyInfo: Family composed of six affected individuals and three diseased subjects (III-2, III-3, III-4) were studied. III-4 (proband) presented with a CNS hemangioblastoma and a retinal hemangioblastoma. The mother (II-1) developed cerebellar, medullar and bilateral retinal HBs; two maternal aunts (II-2 and II-3) were affected by retinal and CNS HBs and unspecified renal tumors, whereas his grandfather (I-2) had unspecified abdominal tumors. All these relatives died in their early 30s. A 35-year-old sister (III-2) demonstrated cerebellar HB, right eye retinal HB and renal cell carcinoma, whereas a 32-year-old brother (III-3) presented with cerebellar HB, right eye retinal HB, renal cell carcinoma and pheochromocytoma. A mutation-carrier nephew (IV-2) presented only atrophy of the retinal pigment epithelium. All of these family members were found to have the R82P (c.245G>C) germline VHL variant. Eighteen additional healthy relatives were analyzed and tested negative for the mutation.

      CohortInfo: Two families and one apparently non-familial case were studied at the Institute of Ophthalmology ‘Conde de Valenciana’ (Mexico City, Mexico).

    1. The index case was a 14 year-old boy who presented to us in 1971 with severe hypertension. On evaluation he was found to have a right adrenal mass with elevated urinary VMA (normal <7 mg/24 hr), confirming the diagnosis of a right adrenal pheochromocytoma. He underwent right adrenalectomy and the post-operative period was uneventful. He was subsequently lost to follow. In 1979, he presented to us again with severe headache and recurrent seizures. On examination his pulse rate was 100/min, blood pressure was 160/130 mm of Hg. Cardiac auscultation revealed a loud 2nd heart sound and a 3rd heart sound. There were no murmurs. Examination of the abdomen revealed a palpable mass in the left hypochondrium. This mass was confirmed as a pheochromocytoma. After adequately controlling his blood pressure he underwent left cortical sparing adrenalectomy. The post-operative period was uneventful. He was on steroid replacement that was subsequently withdrawn after his serum cortisol levels had normalized. His 8 AM cortisol after withdrawal of steroids was 12 µg/dl.He subsequently got married and had two children as shown in Figure 1, who also eventually developed similar tumors.

      FamilyInfo: The patient’s mother, deceased at 37Y, previously presented with retinal hemangioblastoma and was found to carry the same mutation as the proband. Genealogical inquiry also revealed that the patient was distantly related to a known VHL family; three members had died with cerebellar hemangioblastoma, although genetic testing was not performed. Another member presented with cerebellar hemangioblastoma, retinal hemangioblastoma, clear cell renal cell carcinoma, and serous cystadenoma at 68Y, adrenal pheochromocytoma at 73Y, and clear cell renal cell carcinoma metastasis in the thyroid at 74Y; he was found to carry the same mutation the patient carried. Another distant member, a 46Y male, also presented with a small renal tumour, renal cysts, and pancreatic cysts. As well, a 10Y male was found to carry the mutation but was asymptomatic. The paper also asserted that two close relatives and a distant relative carried the mutation, although genotyping was not performed and phenotypic information was not provided.

Results for individual PALB2 variants were normalized relative to WT-PALB2 and the p.Tyr551ter (p.Y551X) truncating variant on a 1:5 scale with the fold change in GFP-positive cells for WT set at 5.0 and fold change GFP-positive cells for p.Y551X set at 1.0. The p.L24S (c.71T>C), p.L35P (c.104T>C), p.I944N (c.2831T>A), and p.L1070P (c.3209T>C) variants and all protein-truncating frame-shift and deletion variants tested were deficient in HDR activity, with normalized fold change <2.0 (approximately 40% activity) (Fig. 1a).

      AssayResult: 4.4

      AssayResultAssertion: Indeterminate

      StandardErrorMean: 0.21

      Comment: This variant was reported as c.398C>G p.(Ser133Thr), however the given allele from reference sequence is incorrect and does not match the actual sequence at the given position. The opposite nucleotide change, c.398G>C, gives the reported protein change (p.(Ser133Thr)), and was assumed to be the intended variant. Use this evidence with caution.
