The H-score in vigilin IHC showed a weak correlation with D2-40 and calretinin.  Finally, chi-square tests of the RhoA and vigilin IHC(positive for epithelioid MM and negativity for lung cancer) showed no significant difference compared to the calretinin IHC (p > 0.05) (Table 4). This evidence concerns the gene RHOA and Miyoshi myopathy.
