Abstract

Significance: Skeletal diseases place a huge burden on patients and society, and yet their genetic basis remains poorly understood. In this article, we identify Speckle-type POZ protein (Spop) as a regulator of skeletal development, loss of which leads to shorter digit bones and lower bone density. We also show that, in striking contrast to the current dogma positing Spop as a negative regulator of Hedgehog (Hh) signaling, Spop regulates skeletal development by promoting Indian Hedgehog (Ihh) signaling. Therefore, our work represents an important conceptual advance in the understanding of Ihh signaling and skeletal development and provides a potential new target for the diagnosis and intervention of bone diseases such as osteoporosis.

  • Among genes harboring an excess of HF SNCs associated with specific facial features, we find RUNX2, EDAR, GLI3, NFATC1, SPOP, DDR2 and NELL1, possibly carrying changes in regulatory regions.

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.
