Case: M, 33Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: Genetic analysis of the patient's parents and brothers, who were unaffected, confirmed a diagnosis of de novo VHL disease.

CaseHPOFreeText: He was admitted to the hospital with a two-month history of progressive right flank pain, accompanied by a one-month history of recurrent painless gross hematuria. The patient's previous medical history included urological surgery at the age of 23 years due to an epididymal cyst and an ophthalmologic surgery at 26 years of age for retinal detachment resulting from bilateral retinal angiomatosis. Contrast-enhanced computed tomography (CT) scanning and angiography were used to detect the presence of quasi-circular enhancing lesions in the middle of the left kidney and large irregular enhancing lesions in the right kidney, extending into the vena cava, that formed an embolus. In addition, multiple cysts in the pancreas and kidney were detected radiologically. The patient underwent a radical nephrectomy with an embolectomy of the right kidney for treatment of T3b-stage renal cell carcinoma. After three months, he successfully underwent laparoscopic nephron-sparing surgery (NSS) of the left kidney. Histological analysis of the renal tissue revealed clear cell carcinomas.

Case: M, 35Y0M, Hungarian

DiseaseAssertion: VHL

FamilyInfo: Index patient presented with cerebellar hemangioblastoma, renal cysts, pancreatic cyst and bilateral renal cell carcinomas. Family members were not available for clinical and genetic screening except a brother whose screening revealed no abnormality.

CasePresentingHPOs: HP:0006880; HP:0005562; HP:0005584; HP:0001737 (Cerebellar hemangioblastoma, Multiple renal cysts, Renal cell carcinoma, Pancreatic cysts)

CaseHPOFreeText: Patient was operated for cerebellar hemangioblastoma at the age of 33 years. Preoperative clinical screening also showed renal cysts. Two years later, a pancreatic cyst and bilateral renal cell carcinomas were found and the patients underwent bilateral nephrectomy with subsequent chronic hemodialysis. Diagnosed with VHL Type 1.

VariantEvidence: A point mutation (c.712C>T) was found. Being that this variant is out of bound with respect to the NM_000551.3 reference sequence, it was concluded that this variant is noted in the Latif et al. (1993) reference and was translated to c.499C>T (NM_000551.3).
