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: patient has a germline deletion of VHL gene demonstrated by loss of one open-reading frame signal detected by g7 cDNA probe. Renal cell carcinoma sample from this patient shows a missense somatic mutation I151S(c.452T>G) in the second copy of VHL gene.
MutationType: missense_variant; transversion
