    • 3. Chronic systemic disorders.
    • 4. Endocrine abnormalities.
  2. Achondroplasia
    • AD; short-limbed dwarfism.
    • activated point-mutation of the fibroblast growth factor receptor 3 (at 4p16.3).
    • incidence increases with paternal age.
    • Epiphyseal growth cartilage fails, but  normal bone formation and repair. homozygous form is usually fatal.
  3. Achondroplasia
    May be diagnosed radiographically at birth, or becomes obvious within the first year with disparity between a large skull, normal trunk length and short limbs.

    X-rays show metaphyseal irregularity, flaring in the long bones, and late-appearing irregular epiphyses
