Von Hippel-Lindau Syndrome: VHL gene analysis

Diagnostic Use

Von Hippel-Lindau syndrome (VHL) is a dominantly inherited familial cancer syndrome predisposing to a variety of malignant and benign neoplasms, most frequently retinal, cerebellar and spinal hemangioblastoma, renal cell carcinoma, pheochromocytoma and pancreatic tumors.

Ambient (8 - 24 degrees Celsius)

Additional Referral/Aliquot Information

Please don’t centrifuge or freeze the EDTA blood tube.
If storing blood tube prior to delivery please refrigerate at 4 degrees (transport still at ambient temperature).

Interpretation

The reported frequency of detection of VHL germline mutations has varied from 39 to 80%. A number of symptomatic patients may not have mutations in the VHL gene due to gene rearrangements, intronic mutations or deletions affecting the VHL gene.

Test Method

Patient DNA is analysed using a Twist Bioscience next generation sequencing (NGS) custom panel on an Illumina MiSeq instrument. The panel targets coding regions and intron-exon boundaries of the VHL gene (LRG_322).

Deletion analysis by MLPA may also be required.
