Methodology and Principal Findings We used a sample of 238 adolescents from a community study characterised by the presence of the short allele of 5-HTTLPR (LL, LS, SS) and the presence or absence of exposure to CA before 6 years of age. We measured cognitive and emotional processing using a set of neuropsychological tasks selected predominantly from the CANTAB® battery. We found that adolescents homozygous for the short allele (SS) of 5-HTTLPR and exposed to CA were worse at classifying negative and neutral stimuli and made more errors in response to ambiguous negative feedback.

In addition, cognitive and emotional processing deficits were associated with diagnoses of anxiety and/or depressions.

Introduction Allelic variation in the promoter region of the serotonin transporter ( 5-HTTLPR), encoded by a single gene (SLC6A4), is partly responsible for regulating serotonergic (5-hydroxytryptamine, 5-HT) functions in the brain.

5-HTTLPR has been considered functionally bi-allelic, where the short (S) allele of this region is associated with lower transcriptional activity, less 5-HT uptake, binding and lower concentrations,. An in vivo study also showed higher rates of 5-HT uptake in platelets for the long (L) compared to the S allele. More recently, research has suggested that an A>G single-nucleotide polymorphism (SNP; rs25531) makes the L allele function similar to the S allele when it is L G rather than L A,,, although this literature is somewhat inconsistent,.
