Genotype-phenotype correlations of 573 VHL patients from 200 kindreds were analyzed and confirmed that higher risk of pheochromocytoma is associated with missense mutations that result in substitution of a surface amino acid or that disrupt the structural integrity of the VHL gene product (pVHL). Age-related risks of retinal hemangoblastomas and renal cell carcinoma were higher in patients with nonsense or frameshift mutations. Southern blot and/or MLPA analysis by whole blood detected this nonsense mutation. c.529A>T was found in 3 VHL families total. 2 families were grouped and detailed as affected with a total of 10 patients, 8 with retinal angioma, 4 with cerebellar hemangioblastoma, 1 with renal cell carcinoma (diagnosed at 50Y), and 1 with pheochromocytoma (diagnosed at 27Y). Another individual belonging to a separate family was written with the same nonsense mutation and retinal angiomas diagnosed at 28Y, cerebellar hemangioblastomas diagnosed at 22Y, and renal cell carcinoma diagnosed at 37Y.

Tissue analysis from 61 VHL patients, 30 sporadic renal cell carcinoma (RCC) tumor samples, and 6 sporadic RCC cell lines revealed 22 variants within VHL patients, 10 variants in tumor samples and variants in all cell lines. All mutations cluster to the 3’ end of the VHL gene open reading frame, implicating this region as important for the tumor-suppressor function of the VHL protein. RT-PCR analysis in RCC cell lines found a p.R177* (c.529A>T) mutation, stated in the paper as c.742A>T due to an older transcript. It was seen in cell line Caki-2. Any family information or other manifestations apart from RCC were unclear.
