Abstract
BACKGROUND: A case of familial bilateral von Hippel-Lindauzon (VHL) renal cell carcinoma (RCC) was retrospectively reviewed and the etiological diagnosis was based on clinical characteristics and genetic testing. METHODS: The clinical manifestations and imaging data were gained from the hospital information system (HIS). Peripheral blood samples were collected and genomic DNA and RNA were extracted. Additionally, mutations of VHL gene such as tiny insertion and deletion of base, point mutation and large deletion of gene were then detected and analyzed by DNA sequencing, real-time quantitative PCR and RT-PCR. RESULTS: Real-time quantitative PCR and RT-PCR products sequencing showed that the number of VHL gene copies in peripheral blood of the patient was decreased, and pathological germline mutation was detected caused by single copy deletion of exon 2 of VHL gene. The patient was diagnosed as atypical VHL RCC according to clinical manifestations and genetic testing outcomes. CONCLUSIONS: VHL RCC can be diagnosed based on its clinical manifestations and genetic testing results. 2019 Annals of Translational Medicine. All rights reserved.
