Figure 4From: Whole exome sequencing detects homozygosity for ABCA4 p.Arg602Trp missense mutation in a pediatric patient with rapidly progressive retinal dystrophy Shows the normal electroretinogram (ERG) responses for a child at this age and the ERG responses obtained at 4 months and 25 months after initial consultation. The ERG is consistent with a modest decrease in both rod and cone mediated retinal function over the course of 21 months.Back to article page
