Loss of heterozygosity of the second VHL allele can be consistently demonstrated in tumor tissue from these patients, suggesting that allelic deletion is a very early or even initiating event for tumorigenesis.

VariantEvidence: germline deletion on chromosome 3 (>35kb, <90kb) resulting in complete loss of VHL gene. Renal cell carcinoma sample from this patient shows a missense somatic mutation R69C(c.205C>T) in the second copy of VHL gene.
MutationType: missense_variant; transition
CivicName: Deletion AND R69C (c.205C>T)
MultipleGeneVariants: Germline, VHL, Gene deletion
