Historical values of GH in blood up to 12 months prior to enrollment in the study will be acceptable. An MRI performed up to 2 years before inclusion in the study is acceptable; History of growth velocity below the mean for the normal population for at least 6 months prior to inclusion in the study, according to the table of VC Tanner (must be historical height data with a minimum of 6 months and maximum of 18 months. Researcher must ensure that the measurements were performed in a standardized way in standard stadiometer (rigid deck and rigid ruler); Baseline IGF-I -0.5 SD for age and sex (results provided by the central laboratory).
