Abstract

The mammalian cerebral cortex is characterized by complex patterns of anatomical and functional areas that differ markedly between species, but the molecular basis for this functional subdivision is largely unknown. Here, we show that mutations in GPR56 , which encodes an orphan G protein–coupled receptor (GPCR) with a large extracellular domain, cause a human brain cortical malformation called bilateral frontoparietal polymicrogyria (BFPP). BFPP is characterized by disorganized cortical lamination that is most severe in frontal cortex. Our data suggest that GPCR signaling plays an essential role in regional development of human cerebral cortex.

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?

  • Mutations in GPR56 coding sequences cause polymicrogyria in most of the neocortex.

    “Mutations in the coding sequences cause polymicrogyria (‘too many small gyri’) in most of the neocortex (Piao et al., 2004).”

    From Genetic Changes Shaping the Human Brain (2015) · cites this paper as Piao et al., 2004

  • GPR56 encodes an adhesion heterotrimeric G protein-coupled receptor that is highly expressed in cortical progenitors and binds extracellular matrix proteins.

    “GPR56 encodes an adhesion heterotrimeric guanine nucleotide–binding protein (G protein)–coupled receptor that is highly expressed in cortical progenitors (7, 16) and binds extracellular matrix proteins (17).”

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.
