218 Also shown is the approximate location of the S206R substitution and the splice junction mutation on the predicted topological map of RmP. Right: ISCEV standard responses and high intensity rod and cone a-waves. Dashed lines show the best ®t of the photoreceptor cone b-waves were signi®cantly delayed in implicit time.
