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.
