Cardiovascular conditions

Hypertrophic cardiomyopathy
A familial incidence of HCM has been hypothesised in the Turkish Van. However, although this disease is anecdotally reported in this breed, to the authors’ knowledge there are no published reports within the scientific literature. In people and in Maine Coon cats HCM can be caused by inherited gene defect(s): as yet no defects have not been identified in the Turkish Van.
