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 mutation: c.272T>A and 273C>A mutations (HGVS nomenclature as c.272_273delinsAA) which leads to this nonsense mutation. It was found in a VHL patient with retinal hemangioblastomas diagnosed at 21Y and cerebellar hemangioblastomas at 23Y. No other family info mentioned.
