Mode of inheritance: Autosomal dominant
Disease-related: yes
Key variant known: yes
Year key variant first reported: 2025
Cross-species summary: Abnormally brittle bones that fracture easily due to variants in the COL1A2 gene.
Molecular basis: Jacinto et al. (2025) investigated two aborted half-sib Stabiliser calves with osteogenesis imperfecta. Whole genome sequencing identified a likely "heterozygous missense variant in exon 21 of [the functional candidate gene] COL1A2, located in the triple-helical region (Chr4:g.11792118G > A; c.1156G > A; p.Gly386Arg) [omia.variant:1837]. ... The variant may be a de novo mutation inherited from a germinal mosaic sire."
Breed:
Stabiliser, United Kingdom of Great Britain and Northern Ireland (Cattle) (VBO_0004811).
Breeds in which the phene or likely causal variants have been documented. If a likely causal variant has been documented, see variant-specific breed information in the variant table. (Breed information may be incomplete).

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.
