OMIA:001366-9031 : Retinal dysplasia and degeneration in Gallus gallus (chicken) |
Categories: Vision / eye phene
Links to possible relevant human trait(s) and/or gene(s) in OMIM: 603785 (gene) , 615219 (trait)
Mendelian trait/disorder: yes
Mode of inheritance: Z-linked
Disease-related: yes
Key variant known: yes
Year key variant first reported: 2011
Species-specific symbol: rdd
Species-specific description: First reported in Scottish commercial chickens by Randall et al. (1979), this disorder was mapped to the Z chromosome by Burt et al. (2003). Comparative mapping suggests a number of candidate genes that are now under investigation (FN: 7 Oct 2003)
Mapping: "Linkage analysis mapped the rdd locus to a small region of the chicken Z chromosome with homologies to human chromosomes 5q and 9p." (Burt et al., 2003)
Molecular basis: Ali et al. (2011) identified a nonsense mutation in the MPDZ gene as the cause of this disorder.
Associated gene:

Variants
By default, variants are sorted chronologically by year of publication, to provide a historical perspective.
Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending
order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column
headers.
WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
