Height of STAT5B deficient patients are comparable to GHR deficient patients. Height SDS values of GHI patients with GHR mutations (black) were compared with height SDS values of STAT5B mutation carriers (blue). Growth Hormone Receptor (GHR) Defects: AR, Autosomal Recessive GHR mutations (n=100); AR pseudoexon, GHR pseudoexon 6Ψ mutations (n=21); DN, Dominant Negative GHR mutations (n=16). STAT5B Defects: DN, Dominant Negative STAT5B mutations (n=11); AR, Autosomal Recessive STAT5B mutations (n=10); AR Carriers, STAT5B mutation carriers (n=14). Box (median, 25th and 75th percentiles) and whiskers (minimum and maximum values) plots; statistical analysis by Student’s t-test, * P<0.05; *** P<0.001; n.s., not significant.
