Effect of ATP8A2 deficiency on visual function as measured by electroretinograms (ERGs). Representative traces of (A) rod (scotopic) and (B) cone (photopic) ERG for 1-month-old WT (black line) and wl/wl (blue line) mice. Quantification of (C) scotopic a-wave and (D) b-wave amplitudes for WT and heterozygous (Het) (n = 9), knockout (n = 6) and wl/wl mice (n = 4). The a- and b- waves are markedly smaller in the mutant mice. **P<0.05 between WT and knockout or wl/wl mice. Error values represent s.e.
