Species-specific description: Information about ACAN related dwarfism in Bos indicus cattle was moved from OMIA:001271-9913 : Dwarfism, ACAN-related in Bos taurus to this Bos indicus entry [19/06/2023]
Molecular basis: Struck et al. (2018) reported a different likely causal variant (ACAN:c.5686insC; p.Val1898fsTer9), homozygosity for which results in a very similar type of dwarfism in the Miniature Zebu breed: the variant was "homozygous in the affected calf and heterozygous in its [Miniature Zebu] parents".
Have human generated variants been created, e.g. through genetic engineering and gene editing
Miniature Zebu, United Kingdom of Great Britain and Northern Ireland (Cattle) (VBO_0004799).
Breeds in which the phene has been documented. For breeds in which a likely causal variant has been documented, see the variant table below

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.
