The IGF1 gene influences circulating levels of the IGF1 hormone which is necessary for muscle growth and development. We test for two variations of the IGF1 gene (IGF1 and IGF1_2), which code for the same protein, but have a slightly different effect on the protein’s function, and ultimately on the physical trait of performance. Your FitnessGenes result for IGF1_2 will identify how your circulating IGF1 levels are affected and how this impacts you.
