Expression of the dopamine transporter gene is regulated by the 3′ UTR VNTR: Evidence from brain and lymphocytes using quantitative RT-PCR

Abstract

Genetic association studies provide considerable evidence that the 10-repeat allele of a variable number tandem repeat (VNTR) in the 3'-untranslated region (3'-UTR) of the dopamine transporter gene (DAT1) is associated with a range of psychiatric phenotypes, most notably, attention deficit hyperactivity disorder. The mechanism for this association is not yet understood, although several lines of evidence implicate variation in gene expression. In this study, we measured DAT1 messenger RNA levels in cerebellum, temporal lobe, and lymphocytes using quantitative real-time reverse-transcription polymerase chain reaction. Relative to a set of four control housekeeping genes (beta-actin, GAPD, ribosomal 18S, and beta2-microglobulin) we observed that increased levels of DAT1 expression were associated with the number of 10-repeat alleles. These data provide direct evidence that the VNTR, or another polymorphism in linkage disequilibrium with the VNTR, is involved in regulating expression of this gene.

  • DAT binding site density is significantly less for the 9-repeat allele than the 10-repeat allele, linking the 9-repeat allele with reduced DAT expression and greater striatal synaptic DA, although some studies suggest the opposite.

    “The DAT binding site density for the most common repeat alleles (9-repeat and 10-repeat) is significantly less for the 9-repeat allele than the 10-repeat allele, linking the 9-repeat allele with reduced DAT expression and greater striatal synaptic DA (Fuke, Suo et al. 2001; Mill, Asherson et al. 2002; VanNess, Owens et al. 2005), although some studies have suggested the opposite (Mill, Asherson et”

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.
