High adherence is important because timely and adequate treatment with GH enables children with GHD and non-GHD conditions, such as chronic renal failure, Turner syndrome and for children born SGA, to achieve an adult height close to or within the normal range.[37–39] Strengths of the use of case studies include their obvious real-world clinical relevance, while their weakness is in the specificity of the individual cases, which do not allow generalized extrapolation to other patients. The gene discussed is GH1; the disease is Turner syndrome.
