Strain description

IRD2 mice become spontaneous inheritable rod dysfunction, and they are observed late-onset progressive retinal degeneration. It's considered that the cause of rod dysfunction is the deletion of Trα protein caused by nonsense mutation of Gnat1 gene. The rod function is normal. It's considered that this strain is useful for the research of inheritable retinal disease. This strain is derived from Crj:CD-1(ICR). It's possible to supply IRD1 mice observed rod and cone dysfunction.
