Our study provides evidence for alterations in hippocampal shape and decreased integrity of the WM region associated with the hippocampus in MDD, and for the possible influence of BclI C/G polymorphism (rs41423247) on hippocampal shape and integrity of the parahippocampal subdivision of the cingulum in depression.
In a sample of 800 healthy participants, we genotyped for the BCL1 rs41423247 and the CHRNA4 rs1044396 single-nucleotide polymorphisms and assessed depressiveness by means of the Beck Depression Inventory.
