Species-specific description: See also entries for osteogenesis imperfecta for which likely causal variants have so far not been identied: 'OMIA:000754-9615 : Osteogenesis imperfecta, generic' or types of the disease caused by variants in other genes, e.g., "OMIA:002112-9615 Osteogenesis imperfecta, COL1A2-related' and 'OMIA:001483-9615 Osteogenesis imperfecta, SERPINH1-related'

Molecular basis: By cloning and sequencing a very likely comparative candidate gene (based on the homologous human disorder), Campbell et al. (2000) showed that the disorder in a Golden Retriever was due to "a G to C point mutation for nucleotide 1,276 [of the COL1A1 gene], predicting a codon change from glycine (GGA) to alanine (GCA) for amino acid 208. This change disrupts the normal Gly-X-Y pattern of the collagen triple helix."

Clinical features: Campbell et al. (2000): "a 12-week-old male golden retriever puppy of small stature ... had multiple fractures in various stages of healing affecting the ribs and nearly every long bone. Dentinogenesis imperfecta was also present."

Breed: Golden Retriever (Dog) (VBO_0200610).

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.
