Regardless of the cutoff used, in the differential diagnosis with clear cell renal cell carcinoma, a statistically significant correlation was found with MiT family translocation renal cell carcinomas and negative expression of CA9 (p = 0.0001) and CD13 (p = 0.0001), with MiT family translocation renal cell carcinomas and positive expression of AMACR (p = 0.0001), cathepsin K (p = 0.0001), and parvalbumin (p = 0.0001 with a 5% cutoff and p = 0.0007 with both a 10% and a 20% cutoff). The gene discussed is PVALB; the disease is hereditary clear cell renal cell carcinoma.
