摘要: RASopathies are a heterogeneous group of syndromes caused by germline mutations in genes encoding components the RAS/MAPK pathway. Postnatal short stature is cardinal feature RASopathies. Although pathophysiology these conditions not fully understood to date, growth hormone insensitivity one possibility, based on observation low IGF-1 values, generally preserved GH secretion and suboptimal response recombinant human therapy. In this review, we will discuss clinical experimental evidence patients with Noonan syndrome other RASopathies, as well their molecular basis.
