Inheritance: Having no access to cats related to the affected kitten born to a stray cat, Takanosu and Kagawa (2022) rightly point out that "we cannot conclude that this disease is inherited." However, as they explain, available evidence (homozygosity for the likely causal variant; mutations in this same gene cause similar inherited disorders in humans and in mice) strongly supports autosomal recessive inheritance.

Molecular basis: Takanosu and Kagawa (2022) described a kitten born to a stray cat in Japan. Having diagnosed the kitten as being affected with osteogenesis imperfecta, the authors performed a whole-genome sequence and then searched for mutations in comparative (human) candidate genes, finding just one likely causal variant, namely a "2-bp deletion in exon 3 of CREB3L1 (c.370_371delTG). This mutation was detected in all sequenced contigs except for the vector end, which indicated homozygosity . . . . The 2-bp deletion mutation caused a frameshift and induced a premature stop codon. (p.C124fs). Sequencing of the PCR product from RT-PCR revealed a 2-bp deletion in the cDNA of CREB3L1 . . . as well."

Clinical features: Takanosu and Kagawa (2022): "Blood and radiographic examinations were performed on presentation. Radiographs revealed decreased opacity of numerous bones. Fractures were observed in some long bones, including femur and tibia."

Pathology: Takanosu and Kagawa (2022): "Histologic examination of the tibia showed decreased osteoid and osteoblasts at the primary spongiosa extending from the growth plate. The periosteum was thickened, and cortical bone and osteoblasts were decreased. Consequently, osteogenesis imperfecta was diagnosed."

Prevalence: Not having access to any family samples from the affected stray cat, Takanosu and Kagawa (2022) genotyped 136 normal cats, none of which carried the likely causal variant.

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.
