Insulin-like growth factor 1 resistance

The insensitivity of the insulin-like growth factor receptor is caused by loss-of-funtion mutations of the IGF1R gene. The pattern of inheritance is variable. Depending on the type of mutation, it may be autosomal dominant or recessive.

Laboratory tests

Labtests show rather elevated EGF1 levels and a normal response to growth hormone stimulation.
