An interaction between BDNF and ELS increased the risk of non-melancholia by 3.327, whereas the interaction between 5-HTT and ELS increased risk by 2.406.
Functional polymorphisms in the interleukin-6 and serotonin transporter genes, and depression and fatigue induced by interferon-alpha and ribavirin treatment.
Also, the more active 5-HTTLPR/5-HTTrs25531 haplotype L(A)L(A) conveyed a significant risk for melancholic depression (OR 2.0; 95%CI 1.3-3.1; P=0.001), again only in the female subsample of patients (OR 2.1; 95%CI 1.1-4.1; P=0.02).
Also, the more active 5-HTTLPR/5-HTT rs25531 haplotype L(A)L(A) conveyed a significant risk for melancholic depression (OR 2.0; 95%CI 1.3-3.1; P=0.001), again only in the female subsample of patients (OR 2.1; 95%CI 1.1-4.1; P=0.02).
Melancholic depression was associated with the 5-HTTLPR long (l) allele and atypical depression with the 5-HTTLPR s-allele (two-sided Fisher's exact test: genotype distribution: P=0.0038; allele frequencies: P=0.007).

The aim of our study was to (a) test for an association between the BDNFVal66Met polymorphism and childhood-onset melancholic depression and (b) to examine the interactive effects of stressful life events (SLE) and the Val66Met polymorphism on the risk of childhood-onset melancholic depression.
Recent post hoc analyses indicated a potential association of three polymorphisms in the BDNF gene with worse treatment outcome in patients with the subtype of melancholic depression.
Increased expression of the Vesicular Glutamate Transporter-1 (VGLUT1) in the prefrontal cortex correlates with differential vulnerability to chronic stress in various mouse strains: effects of fluoxetine and MK-801.

However, BDNFrs7103411 and rs6265 similarly predicted worse treatment response over 6 wk in clinical subtypes of depression such as melancholic depression only (rs7103411: TT < CC, p = 0.003; rs6265: GG < AA, p = 0.001).

No association between polymorphisms and haplotypes of the AVPR1b, CRHR1 and NR3C1 genes and depression with melancholic features in the course of bipolar disorder.
