Abstract
This paper describes a pedigree with Huntington's disease (HD), in which three cases of obsessive‐compulsive disorder (OCD) and two cases of pathological gambling (PG) were identified. The mutation analysis of the HD gene was carried out in the examined individuals who were at risk for HD. In fact, OCD and PG only occurred in carriers of the HD expansion. The possible implications of this finding are discussed.
