The causes of short stature in Turner syndrome / 临床儿科杂志

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) (P0.05). 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.
