CACNA1F and retinal degeneration: Mild progressive retinal degeneration occurs in α1F KO mice, but the more striking morphological feature is that in the absence of Cav1.4 the outer plexiform layer is reduced in thickness by half consistent with defective development of the presynaptic terminal (Mansergh et al., 2005; Chang et al., 2006; Specht et al., 2009; Regus-Leidig et al., 2014; Dai et al., 2019).
