Insensitivity5
- Primary (congenital/hereditary) GH insensitivity may result from growth hormone receptor defects, as in the case of Laron syndrome, but can also be caused by defective post-receptor signal transduction (STAT5B), abnormalities of the IGF-1 gene or IGF-1 receptor. (wikipedia.org)

- IGF-I deficiency can be the result of GH resistance or insensitivity due to genetic disorders of the GH receptor causing GH receptor deficiency (growth hormone receptor deficiency [GHRD], Laron syndrome) or postreceptor defects, including the principal transduction agent STAT5b, the IGF-I/IGFBP3 stabilizer acid labile subunit (ALS), the IGF-I gene, or the IGF-I receptor.

Dwarfism2
