Background: The type I IGF1R plays a role in intrauterine and postnatal growth. Heterozygous IGF1R mutations have been identified in over 20 families. Some of them are linked to the etiology of short stature in previous studies. In addition, we previously reported that a heterozygous nonsense mutation (p.Q1250X) of the IGF1R gene led to decrease IGF1R protein expression through endoplasmic reticulum-associated protein degradation (ERAD) mechanism, resulted in...
