Pathology

- heterozygous loss-of-function mutations in GDF1 contribute to cardiac defects ranging from tetralogy of Fallot (ToF) to transposition of the great arteries (TGA)

  • decreased TGFbeta signaling (TGFBs)
  • perturbations of the TGFbeta signaling pathway (TGFBs) is involved in a major subclass of human cardiac malformations.

- cardiac malformations (congenital heart defects) (CHDs)
- left-right patterning

  • left-right patterning could contribute to the pathogenesis of selected cardiac defects by interfering with the extrinsic cues leading to the proper looping and vessel remodeling of the normally asymmetrically developed heart and vessels.
