Abstract

Comings et al. [1991: JAMA 266: 1793–1800] have recently reported a highly significant association between Tourette's syndrome (TS) and a restriction fragment length polymorphism (RFLP) of the dopamine D 2 receptor gene (DRD2) locus. The A1 allele of the DRD2 Taq I RFLP was present in 45% of the Tourette patients compared with 25% of controls. We tried to replicate this finding by using the haplotype relative risk (HRR) method for association analysis. This method overcomes a major problem of conventional case‐control studies, where undetected ethnic differences between patients and controls may result in a false‐positive finding, by using parental alleles not inherited to the proband as control alleles. Sixtyone nuclear families encompassing an affected child and parents were typed for the DRD2 Taq I polymorphism. No significant differences in DRD2 A1 allele frequency were observed between TS probands, subpopulations of probands classified according to tic severity, or parental control alleles. Our data do not support the hypothesis that the DRD2 locus may act as a modifying gene in the expression of the disorder in TS probands. © 1994 Wiley‐Liss, Inc.

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.
