A gene for regulating normal growth / development

IGF1 (insulin-like growth factor 1), a hormone that promotes cell growth and cell division in both children and adults, is transported through the blood by a molecule called IGF-binding protein 3 (coded by the IGFBP3 gene). It regulates the activity of IGF1 by protecting it against breakdown and preventing it from binding to its receptor.  Variations in this gene affect the levels of IGFBP-3 and IGF1 and may affect body composition.


You can find more information about the IGFBP3 gene in our member area at member.fitnessgenes.com where you can also find your results and what this means for you after your DNA has been analyzed by us. Head over to the shop to order your Fitnessgenes DNA analysis and genetic training system
