A canine chromosome 7 locus confers compulsive disorder susceptibility

Molecular Psychiatry volume 15, pages 8–10 (2010)Cite this article

Human and canine compulsive disorders (CCDs) manifest as time-consuming, repetitive behaviors causing distress and functional impairment. CCDs derive from normal behaviors such as grooming (acral lick dermatitis), predatory behavior (tail chasing, fly snapping), eating/suckling (pica and flank sucking (FS)/blanket sucking (BS)) or locomotion (pacing/circling). They commonly appear between pre-pubescence and early social maturity1 and may be precipitated by anxiety or stress. However, the behavior soon becomes ‘fixed’ and is shown even in the absence of obvious stressors. CCD has compelling parallels with human obsessive–compulsive disorder (OCD).2, 3 OCD, characterized by recurring obsessions and/or compulsions, affects millions of individuals.4 Here, we describe the novel association of Doberman pincher CCD with a chromosome 7 locus containing CDH2, an attractive candidate.
