Abstract: | Neuregulin-1 (NRG1) is associated with schizophrenia. As one of the receptors of NRG1, v-erb-a erythroblastic leukemia viral oncogene homolog 4 (ErbB4) has also been reported to be associated with schizophrenia. Since there can be shared genetic variants among bipolar affective disorder, major depressive disorder and schizophrenia, we tested the association between ErbB4 and these three major psychiatric disorders in the Han Chinese population. Five single nucleotide polymorphisms (SNPs) were selected based on previous positive reports and linkage disequilibrium information of the HapMap Han Chinese individuals from Beijing (CHB) + individuals from Tokyo, Japan (JPT) population. These SNPs were genotyped in 1140 bipolar affective disorder (BPAD) patients, 1140 schizophrenia (SCZ) patients, 1139 major depressive disorder (MDD) patients and 1140 normal controls. Two SNPs (rs707284 and rs839523) showed nominal significance in the BPAD patients but this was eliminated after permutation. No significant association between ErbB4 and the two other psychiatric disorders was observed, nor did haplotype analysis reveal any positive signal. |
