Abstract
Background Classical von Hippel Lindau (VHL) disease/syndrome includes CNS hemangioblastoma, renal or pancreatic cysts, pheochromocytoma, renal carcinoma and exodermic cystadenoma. The syndrome is caused by mutation of VHL tumor suppressor gene. The most prevalent mutations are present in VHL syndrome. To date, > 500 mutations of gene related to the progression of VHL syndrome have been reported. VHL gene mutation presented in single lung or pancreatic tumor has been reported occasionally, but there is no report of both. Methods In this paper, we used CT scan, pathological and genetic examination methods to diagnose a rare atypical VHL syndrome. Results We reported a rare case of atypical VHL syndrome with authenticated VHL mutation at p.Arg167Gln, that was associated with not only bilateral pheochromocytoma but also lung carcinoid and neuroendocrine tumor of pancreas. Based on literature reviews, the patient was recommended to be further subjected to octreotide-based radionuclide therapy. Conclusions Combined with gene detection and clinical diagnosis, we found the inherent relationship between VHL genotype and phenotype, and constructed the standard diagnosis and treatment process of disease with rare VHL mutation from the perspective of gene therapy.

Abstract
Background The Von Hippel-Lindau (VHL) p.Tyr98His (Y98H) mutation is designated as the "Black Forest" founder mutation and has been previously reported in Western countries. This study reports the first recorded Chinese VHL family with the "Black Forest" mutation in Asia. Methods Paired whole-exome sequencing (WES), Sanger sequencing and immunohistochemistry (IHC) were performed on samples from a large Chinese family to confirm the causative mutation and mutation carriers in the family. Clinical manifestations of the family were summarized and compared with those reported from other patients with the VHL Y98H mutation. Results The Chinese pheochromocytoma (PCC) family was identified as a VHL type 2 family with a Y98H mutation. There were 4 VHL patients and 11 currently healthy individuals with the mutation. Copy number analysis and SDHB IHC were performed to exclude interference from other pathogenic genes of PCC or paraganglioma (PGL). Conclusions We report the first recorded instance of a Chinese VHL type 2 family with the "Black Forest" mutation by using WES and Sanger sequencing, which widens the currently recorded presence of the "Black Forest" mutation to China and potentially elsewhere in Asia and indicates that the "Black Forest" mutation does not uniquely evolve in occidental countries. A personalized surveillance approach, which may be more appropriate for affected families, has been recommended to improve quality of life.
