Of these ‘common oHCM-associated’ proteins, the combination of the proteins Fibrinogen gamma-chain (FGG) and Hsp90 co-chaperone Cdc37-like 1 (CDC37L1) was identified based on a binary logistic regression model with forward:wald selection as the optimal combination for differentiation between oHCM and either DCM or ISCM patients (Figure 4C). Here, FGG is linked to familial dilated cardiomyopathy.
