   • Child presenting a GH* deficiency defined by :

   Growth criteria of size (size) < 2 DS) Criteria of speed of growth (speed of growth < 1 DS over the last year) 2 tests of pharmacological stimulation of GH with peak GH max < 20 mUI

   • Child naïve of treatment by GH and that must begin a treatment with GH
   • Child covered by a national insurance scheme or an equivalent
   • Signature of the informed consent by one of both holders of the parental authority * The deficit in GH can be isolated or associated with one or several other hormonal deficits: deficit in TSH, deficit in ACTH, deficit in LH-FSH, deficit in prolactin. The child GHD can thus receive other treatments associated with the growth hormone.
