Mammary gland, limb and yolk sac defects in mice lacking Tbx3,the gene mutated in human ulnar mammary syndrome

Abstract

Spontanteous mutations in the T-box gene TBX3, result in the human ulnar-mammary syndrome, a dominant developmental disorder characterized by abnormal forelimb and apocrine gland development. In order to develop a mouse model to study the role of this gene during development and disease, we produced a mutation in the mouse ortholog, Tbx3. The phenotype of the mutant mice verifies the role of this gene in limb and mammary gland development, and, in addition, reveals a previously unknown role for the gene in the yolk sac, a fetal membrane that is the site of hematopoiesis and is essential for survival during gestation. In homozygous mutant embryos, the yolk sac undergoes cell death and degeneration at midgestation and the fetuses die over a range of several days; none survive to birth. Tbx3 is the first T-box gene implicated in yolk sac development. Homozygous embryos show a deficiency of mammary gland induction, and exhibit both forelimb and hindlimb abnormalities. Although heterozygous mice, unlike their heterozygous human counterparts, have no apparent phenotype in limb or mammary gland, the homozygous defects in the development of these organs represent more severe manifestations of the defects characteristic of the ulnar-mammary syndrome.

  • The phenotypic features of Tbx3-/- embryos, including diminished liver size, have also been observed in another Tbx3 mutant mouse line, but such liver defects were only discussed as an effect of deficiencies in yolk sac or hematovascular development.

    “The phenotypic features of Tbx3 -/-embryos, including a diminished liver size, have also been observed in another Tbx3 mutant mouse line, but such liver defects were only discussed as an effect of deficiencies in the yolk sac or in hematovascular development (Davenport et al., 2003).”

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.
