PatientID: 2

KindredID: 2

Case: F, 50Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: See figure 3 for pedigree. In family 2, the proband (Patient 2 in the paper) was a 50 year old female who presented with bilateral renal cell carcinoma, pancreatic neuroendocrine tumor, and a renal cyst. The proband's sister was diagnosed with a pancratic NET and died of a hemorrhagic stroke at 40 years of age. Their mother also died of a stroke at 50 years of age. Genetic analysis revealed a c.232A>T (p.Asn78Tyr) mutation in the VHL gene of the proband. Based on her clinical presentation and family history, the proband was diagnosed with VHL type 1. Sanger sequencing on her family members detected the same mutation in her mother, sister, brother, and nephew.The proband's brother and nephew refused further VHL-related examination.

CaseHPOFreeText: Referred to hospital in August 2011 for masses in her left kidney. The CT scan showed several masses in her left kidney and the largest one was about 3.1 × 2.4 cm. She underwent a radical nephrectomy 5 years ago for the tumor in her right kidney.
