XXI. SCF LAYMAN’S SUMMARY
Ellis–van Creveld syndrome is a rare inherited developmental disorder caused by mutations affecting proteins that regulate primary cilia and Hedgehog signaling. These abnormalities disrupt normal skeletal growth, limb development, heart formation, teeth development, and nail formation. Individuals typically have short stature, extra fingers or toes, congenital heart defects, and characteristic dental findings. SCF interprets Ellis–van Creveld syndrome as a developmental communication disorder involving ciliary signaling failure, morphogenic dysregulation, skeletal-cardiac developmental instability, and loss of synchronized embryologic patterning.
