IED is characterized by recurrent episodes of aggression in which individuals act impulsively and grossly out of proportion from the involved stressors. Previous studies have identified genetic variants in the serotonergic pathway that play a role in susceptibility to this behavior, but additional contributors have not been identified. Therefore, to further delineate possible genetic influences, we investigated CNVs in individuals diagnosed with IED and\/or personality disorder (PD). We carried out array comparative genomic hybridization on 113 samples of individuals with isolated features of IED (n\u2009=\u200990) or PD (n\u2009=\u200923). We detected a recurrent 1.35\u2010Mbp deletion on chromosome 1q21.1 in one IED subject and a novel \u223c350\u2010kbp deletion on chromosome 16q22.3q23.1 in another IED subject. While five recent reports have suggested the involvement of an \u223c1.6\u2010Mbp 15q13.3 deletion in individuals with behavioral problems, particularly aggression, we report an absence of such events in our study of individuals specifically selected for aggression. We did, however, detect a smaller \u223c430\u2010kbp 15q13.3 duplication containing <jats:italic>CHRNA7<\/jats:italic> in one individual with PD. While these results suggest a possible role for rare CNVs in identifying genes underlying IED or PD, further studies on a large number of well\u2010characterized individuals are necessary. \u00a9 2011
