Our study aims at replicating our previous finding of an association between COMT rs4680 G/A polymorphism and early onset major depression (MD). We included 462 MD, 147 bipolar disorders (BD) subjects and 295 healthy controls. We could partially replicate previous findings. In particular, rs4680 GG + AG genotypes were more represented in the subgroup of early onset MD patients (p=0.04). Additionally, we observed an association between rs737865 alleles and early onset MD (p=0.04). Rs4680 genotype was associated with early onset BD as well (p=0.01). In conclusion, we partially replicated our previous findings confirming a possible influence of COMT variants in MD and BD, particularly in early onset subjects, though not with the same risk genotypes.

Abstract

Our study aims at replicating our previous finding of an association between COMT rs4680 G/A polymorphism and early onset major depression (MD). We included 462 MD, 147 bipolar disorders (BD) subjects and 295 healthy controls. We could partially replicate previous findings. In particular, rs4680 GG + AG genotypes were more represented in the subgroup of early onset MD patients (p=0.04). Additionally, we observed an association between rs737865 alleles and early onset MD (p=0.04). Rs4680 genotype was associated with early onset BD as well (p=0.01). In conclusion, we partially replicated our previous findings confirming a possible influence of COMT variants in MD and BD, particularly in early onset subjects, though not with the same risk genotypes.
