Mice lacking paternal expression of imprintedGrb10show a number of social behaviour deficits, including an enhanced allogrooming phenotype. However, this could also index compulsive behaviour, and the increased whisker barbering seen inGrb10+/pmice has been suggested to be indicative of a trichotillomania-type behaviour. Here we test whether compulsive behaviour is a more general phenotype inGrb10+/pmice by examining marble burying at three different adult ages (2, 6 and 10 months). We also examined the mice for potentially confounding anxiety phenotypes using the elevated plus maze (EPM).Grb10+/pmice showed no difference from wild-type littermate controls on any measure in the marble burying test at any age. There was no difference in standard anxiety measures either, althoughGrb10+/pmice displayed more risk-taking behaviours on the EPM than wild-type mice. These data suggest thatGrb10+/pmice are not generally more compulsive, and that the enhanced allogrooming is probably indicative of altered social behaviour. Furthermore, the altered behaviours seen on the EPM adds to other published findings suggesting thatGrb10, and imprinted genes more generally, have a role in mediating risk-taking behaviour.
