The following phenotype information may relate to a genetic background differing from this JAX® Mice strain.
In(4)56Rk/+ Rd4/Rd4+
involves: C57BL/6J * DBA/2J
- vision/eye phenotype
- abnormal eye electrophysiology
- in mutants, the electroretinogram is never normal (MGI Ref ID J:41514)
- abnormal ocular fundus morphology

| Allele Symbol | In(4)56Rk | ||
|---|---|---|---|
| Allele Name | inversion, Chr 4, Roderick 56 | ||
| Allele Type | Radiation induced | ||
| Strain of Origin | (DBA/2J x C57BL/6J)F1 | ||
| Gene Symbol and Name | In(4)56Rk, inversion, Chr 4, Roderick 56 | ||
| Chromosome | 4 | ||
| Gene Common Name(s) | In56Rk; | ||
| General Note | This inversion is homozygous lethal. | ||
| Molecular Note | This is a large inversion on Chromosome 4 which arose in a DBA/2J male exposed to 1000R of radiation. It covers most of chromosome 4 with the breakpoints in G bands 4A1 and 4E2. The distal breakpoint of the inversion is in the second intron of the Gnb1gene and the proximal breakpoint lies within the centromere. [MGI Ref ID J:108450] [MGI Ref ID J:41514] | ||
| Allele Symbol | Rd4 | ||
| Allele Name | retinal degeneration 4 | ||
| Allele Type | Spontaneous | ||
| Strain of Origin | DBA/2J-In(4)56Rk | ||
| Gene Symbol and Name | Rd4, retinal degeneration 4 | ||
| Chromosome | 4 | ||
| General Note | The Rd4 mutation is an autosomal dominant retinal degeneration found in a stock carrying the large Chr 4 inversion In(4)56Rk. The inversion is homozygous lethal and in heterozygotes is always associated with retinal degeneration. The distal break point of In(4)56Rk is in Gnb1. | ||
| Molecular Note | Rd4 is an autosomal dominant retinal degeneration found in a stock carrying the large Chr 4 inversion In(4)56Rk. Rd4 did not recombine with the inversion in an outcross, suggesting that the Rd4 locus is located very close to or is disrupted by one of thebreakpoints of the inversion on Chr. 4, either near the centromere or near the telomere. | ||
