Genotype-phenotype correlations of 573 VHL patients 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). This missense mutation (c.538A>G), affecting residue within the pVHL protein core, was found in a VHL patient with renal cell carcinoma diagnosed at 27Y. ACMG codes as follows: Supporting evidence of pathogenicity because Missense variant in a gene that has a low rate of benign missense variation and where missense variants are a common mechanism of disease (PP2).
