We have previously reported an association between the BDNF Val66Met polymorphism and bipolar disorder (BD). However, the possibility that genomic imprinting in BDNF gene affects risk for BD has not been investigated. To examine the possibility of genomic imprinting in the BDNF gene in BD, we analyzed the parent-of-origin effect (POE) and differential expression of the BDNF Val66Met alleles in BD. We performed a family-based association study and ETDT analyses of the Val66Met polymorphism in 312 BD nuclear families, and compared allele-specific mRNA levels in both post-mortem brain samples and B lymphoblasts from BD patients and controls. The BDNF Val66 allele was transmitted significantly more often to patients with BD (maternal transmissions: 46/22, p=0.003; paternal transmissions: 55/30, p=0.006). There was no significant difference between maternal and paternal transmission ratios. There was no significant difference in the ratio of Val/Met-specific mRNA expression between BD and controls, in either brain or B lymphoblasts. The Val/Met ratio was much lower in the brain vs. B lymphoblasts. These data do not support a role for genomic imprinting as a modifier of the contribution of BDNF gene to risk of susceptibility to BD.
