Canine hip dysplasia (CHD) is a common congenital hereditary disease characterized predominantly byhip joint relaxation. While both environmental and genetic factors are known to contribute to the disease, the underlyingmechanism of pathogenesis remains unknown. In recent years, significant progress has been achieved in the genomics ofCHD. For example, a quantitative trait locus (QTL) was identified for CHD that is associated with the Norberg angle of thehip joint, the dorsolateral subluxation score and the separation index. In addition, genes such as FBN2, LRR1, COL6A3and FN1 have been shown to be associated with CHD. In this review, we summarize current research in this field, withparticular focus on the chromosomal position of the identified QLT and the known functions of candidate disease-causing genes associated with CHD.
