Mutations are changes in DNA that can lead to short stature by disrupting the intricate process of bone growth, primarily affecting the growth plate, where bone elongation occurs. Specific examples include mutations in the ACAN gene, which affects cartilage, and genes like IHH and those in the RAS-MAPK pathway, impacting chondrocyte function and signaling vital for bone development. These genetic changes can cause abnormal cartilage matrix synthesis or disrupt signaling pathways, resulting in a spectrum of growth abnormalities, from minor limb shortening to severe skeletal deformities.Â
