ABSTRACT
【Objective】 To explore the mutation type, clinical characteristics, molecular genetics and the two-hit type of a patient with familial Von Hippel Lindau (VHL) syndrome. 【Methods】 The data of the patient were collected. DNA was extracted from the peripheral blood and renal cell carcinoma sample. The VHL gene germline mutation site was detected with high throughput sequencing next generation sequencing (NGS). The two-hit site was identified with UCSCXena database, methylation-specific PCR (MSP) and microsatellite stability detection. 【Results】 The mutation site of the embryo line was located in c.500G>A R167Q mutation. The patient had single nucleotide polymorphism, but no clear loss of heterozygosity, methylation or system mutation. 【Conclusion】 The germline mutation in exon 3 is the basis for the clinical features of this familial renal cell carcinoma proband. The identification of the two-hit site is key to the occurrence of the disease, which is significant for the diagnosis and treatment. The use of the databases can guide the screening of mutations and methylation sites in familial renal cell carcinoma.
