The updated VCOG-CTCAE v2 guidelines contain several important updates and additions since the last update (v1.1) was released in 2011 published within Veterinary Comparative Oncology 2016. As Cooperative Group (VCOG) is no longer an active entity, original authors contributors to v1.0 v1.1 were consulted for input, additional co-authors sought expansion refinement of adverse event (AE) categories. includes expanded neurology, cardiac immunologic AE sections, addition procedural-specific...
Two FGF4 retrogenes on chromosomes 12 (12-FGF4RG) and 18 (18-FGF4RG) contribute to short-limbed phenotypes in dogs. 12-FGF4RG has also been associated with intervertebral disc disease (IVDD). Both of these were found be widespread among dog breeds allele frequencies ranging from 0.02 1; however, their additive contribution is unknown. Surgical cases IVDD (n = 569) evaluated for age onset, calcification, genotypes the retrogenes. Multivariable linear regression analysis identified presence...
