Abstract: Objectives To investigate the causes of short stature in Turner syndrome (TS). Methods 86 patients were di-agnosed with TS by karyotypes from 2004 to 2013. According to the deletion types of the X chromosome short arm, growth hor-mone (GH), insulin-like growth factor-1 (IGF-1) and thyroid function, the TS patients were divided into different groups and com-parison was made among groups. Results Ht SDS in three groups with different extent of the deletion of the X chromosome short arm were (-4.39±1.08), (-3.26±1.25) and (-2.84±0.15) (P<0.05). The proportion of growth hormone deifciency (GHD) in the three groups were 62.5%, 38.9%and 0%(P<0.05). Ht SDS in groups with different degree of IGF-1 level were (-4.37±1.10), (-3.82±1.07) and (-3.25±0.91) (P<0.05). There was no signiifcant difference of Ht SDS between hypothyroidism patients with and without GHD (P>0.05). Conclusions The deletion of X chromosome short arm may cause the short stature in TS. The GH-IGF-1 axis in TS is impaired, but GHD is not related to short stature in TS.
