Nucleic acids comprising the neuregulin 1 gene (NRG 1) and encoding NRG 1 polypeptides are disclosed. Also described are related nucleic acids encoding NRG 1 polypeptides; NRG 1 polypeptides; antibodies that bind to NRG 1 polypeptides; methods of diagnosis of susceptibility to schizophrenia; assays for agents that alter the activity ofNRG 1 polypeptide or which identify NRG 1 binding agents, and the agents or binding agents identified by the assays; NRG 1 therapeutic agents, including i the NRG 1 nucleic acids, NRG 1 polypeptides, or agents that alter the activity of an NRG 1 polypeptides; pharmaceutical compositions comprising the NRG 1 therapeutic agents; as well as methods of therapy of schizophrenia. Novel haplotypes with a common core haplotype in affected individuals are described, as well as their use in methods for screening for susceptibility to schizophrenia. Also described are hypomorphic mice for use in identifying phenotypes associated with schizophrenia, as well as for use in assessing agents of interest for neuroleptic activity and for potential therapeutic use for treatment of schizophrenia.

L'invention porte sur: des acides nucléiques comportant le gène de la neuréguline 1 (NRG1) et codant pour les polypeptides NRG1; sur des acides nucléiques codant pour les polypeptides NRG1; sur des acides nucléiques apparentés codant pour les polypeptides NRG1; sur les polypeptides NRG1; sur des anticorps se fixant aux polypeptides NRG1; sur des procédés de diagnostic de la susceptibilité à la schizophrénie; sur des essais de recherche ou d'identification d'agents modifiant l'activité des polypeptides NRG1, et sur les agents ainsi identifiés; sur des agents thérapeutiques du NRG1, dont les acides nucléiques du NRG1, les polypeptides NRG1, et les agents modifiant l'activité des polypeptides NRG1; sur des préparations pharmaceutiques comprenant des agents thérapeutiques du NRG1; et sur des procédés de traitement de la schizophrénie. L'invention porte également sur de nouveaux haplotypes à noyau commun de patients affectés et sur leur utilisation pour le criblage de la susceptibilité à la schizophrénie. L'invention porte en outre sur une souris hypomorphe servant à identifier les phénotypes associés à la schizophrénie, sur son utilisation pour déterminer des agents d'intérêt pour l'activité neuroleptique, et sur son utilisation thérapeutique potentielle dans le traitement de la schizophrénie.
