OMIA 002126-9615 : Osteogenesis imperfecta, type III, COL1A1-related in Canis lupus familiaris

Possibly relevant human trait(s) and/or gene(s) (MIM number): 259420

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Dominant

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2000

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."

Breed: Golden Retriever.

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.
