The authors described the growth kinetics of 96 renal tumours in 64 VHL patients (32 males, 32 females). All patients had VHL disease with renal involvement. 54/64 had undergone renal surgery or a radiofrequency thermal ablation procedure for RCC. In 10/64 patients, at least one or more RCC was diagnosed. However, at the time of diagnosis, an indication for treatment was not yet present. For all patients, several CT/MRI scans existed for retrospective description of tumour growth kinetics. 10-ml EDTA anticoagulated blood samples were available from each patient for mutation screening of all exons of the VHL gene. Genomic DNA from blood samples was extracted using standard methods. Small deletions/insertions or point mutations were identified by DNA sequencing followed by complete mutation screening using PCR/single-strand conformation polymorphism and denaturing high-performance liquid chromatography. A germline deletion p.R177Dfs*25 (c.528del) was identified in patient #49. This mutation was noted as c.740delG in the paper due to a difference in reference transcript used (see Table S5). No family information is available for this patient.
