The human receptor tyrosine-protein kinase erbB-4 (ERBB4) gene mediates neuregulin 1 (NRG1) signaling, and is involved in neuronal migration and differentiation. Despite the potential significance of ERBB4 in the development of schizophrenia, relatively few genetic studies for the association of ERBB4 with schizophrenia were performed in the populations including Ashkenazi Jews, Americans including Caucasians and African Americans, and Han Chinese. In this study, differences in ERBB4 variations were investigated to determine association with schizophrenia and smooth pursuit eye movement (SPEM) abnormality in a Korean population. Seven polymorphisms in ERBB4 gene were genotyped in 435 schizophrenia cases and 390 unrelated healthy controls. In order to investigate the relationship between ERBB4 and the risk of schizophrenia and SPEM abnormality, differences in SNP and haplotype distribution were analyzed using logistic and multiple regression analyses. However, we failed to replicate the associations reported by previous studies in other populations. Although statistically not significant, the tendency towards associations between ERBB4 polymorphisms and the risk of schizophrenia and SPEM abnormality in this study from a Korean population would be helpful for further genetic etiology studies in schizophrenia.
