Several genes have been associated with higher risk of SCD including lamin A/C protein, phospholamban (PLN), sodium voltage-gated channel alpha subunit 5 (SCN5A), RNA binding motif protein 20 (RBM20), filamin C (FLNC), and desmoplakin (DSP) [34, 35]. Here, PLN is linked to Schnyder corneal dystrophy.
