Abstract

Sagittal craniosynostosis is the most common form of craniosynostosis, affecting approximately one in 5,000 newborns. We conducted, to our knowledge, the first genome-wide association study for nonsyndromic sagittal craniosynostosis (sNSC) using 130 non-Hispanic case-parent trios of European ancestry (NHW). We found robust associations in a 120-kb region downstream of BMP2 flanked by rs1884302 (P = 1.13 × 10(-14), odds ratio (OR) = 4.58) and rs6140226 (P = 3.40 × 10(-11), OR = 0.24) and within a 167-kb region of BBS9 between rs10262453 (P = 1.61 × 10(-10), OR = 0.19) and rs17724206 (P = 1.50 × 10(-8), OR = 0.22). We replicated the associations to both loci (rs1884302, P = 4.39 × 10(-31) and rs10262453, P = 3.50 × 10(-14)) in an independent NHW population of 172 unrelated probands with sNSC and 548 controls. Both BMP2 and BBS9 are genes with roles in skeletal development that warrant functional studies to further understand the etiology of sNSC.

  • The penetrance of SMAD6 variants appears to be modified by common regulatory variation near BMP2.

    “Strong evidence supports a role for the BMP/SMAD pathway, particularly through SMAD6, whose variants represent one of the most consistent findings in midline NCS [62]; importantly, their penetrance appears to be modified by common regulatory variation near BMP2, supporting a two-locus model rather than a simple monogenic one [76].”

    From Genetics versus environment in the pathophysiology of sagittal synostosis (2026) · cites this paper as [76]

    The paper reports common variants associated with sagittal craniosynostosis near BMP2 and predicts a regulatory element in that region (association findings and discussion; page unavailable). It does not report SMAD6 variants or show that BMP2-region variation modifies their penetrance. Its discussion treats gene–gene interactions as a possibility, not an established two-locus model. (LLM, conf=0.86)

  • A two-locus model rather than a simple monogenic model is supported for SMAD6/BMP2 in sCS.

    “Strong evidence supports a role for the BMP/SMAD pathway, particularly through SMAD6, whose variants represent one of the most consistent findings in midline NCS [62]; importantly, their penetrance appears to be modified by common regulatory variation near BMP2, supporting a two-locus model rather than a simple monogenic one [76].”

    From Genetics versus environment in the pathophysiology of sagittal synostosis (2026) · cites this paper as [76]

    The paper reports an association between variation near BMP2 and sagittal craniosynostosis and says the lack of Mendelian segregation suggests complex inheritance (Abstract; page unavailable). It does not establish that BMP2 variation modifies the penetrance of SMAD6 variants or support the specific SMAD6/BMP2 two-locus model; its tested gene–gene interactions were not significant after correction (Abstract; page unavailable). (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Susceptibility loci near BMP2 and within BBS9, as well as functional evidence implicating ciliogenesis and primary cilium biology, are relevant to sagittal suture homeostasis.

    “This is further reinforced by the identification of susceptibility loci near BMP2 and within BBS9, as well as functional evidence implicating ciliogenesis and primary cilium biology in sagittal suture homeostasis [44, 76].”

    From Genetics versus environment in the pathophysiology of sagittal synostosis (2026) · cites this paper as [76]

    The Abstract (page unavailable) reports replicated susceptibility loci near BMP2 and within BBS9. It also links BBS9 to ciliary transport and discusses primary-cilium signaling, but says that BBS9’s effect on suture fusion remains unknown. It does not provide functional evidence that ciliogenesis or primary cilia maintain sagittal suture homeostasis. (LLM, conf=0.88)

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.
