Abstract

AIM: Previous studies have shown an association between childhood attention deficit hyperactivity disorder (ADHD) and a down-regulated hypothalamus-pituitary-adrenal axis (HPA axis) with low diurnal cortisol levels. Given the role of the FK506 binding protein 5 (FKBP5) as an important regulator of the negative feedback system of the HPA axis, we set out to investigate possible associations between single nucleotide polymorphisms (SNPs) in FKBP5 in relation to ADHD and diurnal cortisol levels. METHODS: Children with ADHD (n = 81) and healthy comparisons (n = 88) collected saliva four times during a regular school day for radioimmunoassay analysis of cortisol and for genotyping of five SNPs in FKBP5 (rs9296158, rs1360780, rs9470080, rs7748266 and rs9394309). RESULTS: We found associations between SNP genotypes and ADHD as well as between genotypes and diurnal cortisol levels. One of these SNPs, rs9470080, was significantly associated with both ADHD and lower cortisol levels. CONCLUSION: This study contributes to previous findings on a down-regulated HPA axis in children with ADHD by demonstrating an association between ADHD, lower cortisol levels and SNPs of the FKBP5-gene. The relevance of these findings for the development and shaping of ADHD symptoms needs to be approached in larger samples, preferably also taking stress reactivity into consideration.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
