OMIA:000240-8839 : Crest in Anas platyrhynchos (Mallard)
Categories: Integument (skin) phene
Links to MONDO diseases: No links.
Mendelian trait/disorder: yes
Considered a defect: yes
Key variant known: yes
Year key variant first reported: 2023
Cross-species summary: Also called feather-crested head.
Molecular basis: Chang et al. (2023) identified a likely causal variant for the crested cushion in Chinese crested ducks in the 5′UTR of TAS2R40 (123272114_c. G78A of TAS2R40).
Have human generated variants been created, e.g. through genetic engineering and gene editing

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
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.
