This retinal degeneration mutation was discovered in conjunction with Scn8anmf5 during an ENU mutagenesis screen at the Neuroscience Mutagenesis Facility at The Jackson Laboratory. Genetic studies demonstrated that a separate gene other than Scn8a was responsible for the retinal phenotype. Candidate gene testing showed that no coding or splice site mutation was present in Pde1b.
