Аннотация
BACKGROUND: Von Hippel-Lindau (VHL) syndrome is a familial autosomal dominant hereditary neoplastic disease caused by mutations in the VHL gene. Approximately 503 kinds of VHL gene mutations have been reported. Different types of mutations manifest various clinical phenotypes, from benign to malignant tumours or coexisting cysts. Thus, a gene mutation test is essential in the diagnosis of VHL syndrome.
CASE PRESENTATION: We reported two cases in which a novel mutation site in the c530-536delGACTGGA region in exon 3 of the VHL gene resulted in the development of VHL syndrome. According to the ACMG guidelines, this variation is pathogenic and consistent with autosomal dominant inheritance. This variation has not been reported anywhere in the databases or literature.
CONCLUSION: This report will add a new mutation site to VHL gene databases. The newly added gene mutation and its associated clinical phenotypes will help improve the accuracy of VHL diagnosis and benefit the community of VHL gene mutation carriers.
