Sex differences in brain expression of X- and Y-linked genes

Xu, Jun, Disteche, Christine M.·2006·Brain Research

Abstract

The X chromosome plays an important role in brain development and function, as evidenced by its disproportionately high content of genes whose mutations cause mental retardation. These X-linked brain genes may play a role in sexual differentiation if they are expressed at a higher level in XX females than in XY males, due to incomplete X inactivation in females. The expression of several X escapee genes is indeed higher in brain tissues from females when compared to males. In mouse, some of the sex differences are only found in adult brains but not in other tissues. Determining the brain expression pattern of these X escapee genes is important for a better understanding of their role in the neurological phenotypes of XO Turner syndrome.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

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.
