OMIA 001612-9031 : Oligozeugodactyly in Gallus gallus
Category: Limbs / digit / tail phene
Links to MONDO diseases: No links.
Mendelian trait/disorder: yes
Considered a defect: yes
Key variant known: yes
Year key variant first reported: 2011
Species-specific symbol: ozd
History: This limb mutant was first reported by Ros et al. (2003).
Molecular basis: Maas et al. (2011) reported that "the spontaneously occurring chicken ozd mutant contains a large deletion in LMBR1-intron 5, eliminating most of the limb-specific enhancer conserved sequence."
Clinical features: "The limbs of this mutant have a longitudinal postaxial defect, lacking the posterior element in the zeugopod (ulna/fibula) and all digits except digit 1 in the leg." (Ros et al., 2003)

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.
