The present study aims to examine the potential correlation between the 4977 bp deletion of mitochondrial DNA (mtDNA) and MDD.Methods: The 4977 bp deletion of mtDNA was detected in the peripheral blood of 253 MDD patients and 257 healthy controls, with depression assessed by the Hamilton Depression Rating scale and functioning by the Global Assessment of Function Scale.Results: MDD patients had a higher incidence of the 4977 bp deletion, unaffected by demographic or clinical factors.Conclusion: The 4977 bp deletion may be a trait marker for MDD.Keywords: major depressive disorder, mitochondrial DNA deletion, mtDNA deletion, 4977 bp deletion
