Overview
Screening
Genetic screening indications:[1]
- Early onset of growth failure
- Positive family history and possible consanguinity
- Height more than 3 sd below the mean
- Extremely low GH response to provocation tests, including GHRH, and very low IGF-I and IGF-binding protein-3 (IGFBP-3) levels
- GHD patients have been screened for mutations in the GH1 and GHRH gene.[2]
- A recent study recommended testing for GH1 and GHRHR mutations in children with severe GHD and a family history of GHD.[3]
- The patient with HMGA2 mutation had severe short stature, low IGF-I, abnormal response to provocative GH testing, and abnormal MRI, and responded well to growth hormone therapy.[4] The importance of the HMGA2 gene in growth has been described through a study of patients with 12q14 microdeletion syndrome, which is characterized by developmental delay, severe short stature, and abnormal facies.[5]
- Testing for a polymorphism in the IGFBP-3 gene may also aid in the diagnosis of GHD and prediction of response to therapy. [6]
- Understanding of genetic contributions to GHD opens the possibility for a more rational approach to the diagnosis and management of GHD.[7]
