    2. Approach
      1. Determine if growth is truly delayed (see indications above)
        1. See Calculation of Growth Delay
      2. Determine when growth delay began (in-utero, perinatal or childhood)

    6. Dysmorphic non-proportional
      1. Consider chondrodystrophy
    7. Normal Growth Velocity (>5 cm/year) and delayed Bone Age
      1. Constitutional growth delay (or Delayed Puberty)
