The Expression of IGF Type 1 Receptor is Increased in Obese Children

Ricco Rafaela , Custodio Rodrigo , Atique Patricia , Liberatore Raphael , Ricco Rubens , Martinelli Carlos

Background: Obese children are often taller than non-obese ones before puberty. Reports on the GH/IGF system in obese children are not consistent and do not explain the increased height observed. Changes in IGF1 bioavailability/bioactivity have been claimed as a possible explanation, however, no data is available regarding the expression of the IGF type 1 receptor (IGF1R) gene.Objective and hypotheses: To study the expression of IGF1R gene in obese child...

Background: Growth spurt is a major event in central precocious puberty (CPP). GnRH analogue (GnRHa) therapy inhibits gonadal axis and decreases height velocity. However, serum IGF1 and IGFBP-3 remain high as before therapy. Reports on IGF type 1 receptor (IGF1R) in CPP are yet unavailable.Aim: To study IGF1R mRNA expression in girls with CPP before and during GnRHa therapy.Methods: 34 girls with CPP were studied. Sixteen of them (...

Introduction: Growth disorders are often caused by monogenic conditions, and genetic investigation should be guided by clinical findings. However, in children with ISS, the absence of specific clinical features prevents the candidate gene approach. ACMG practice guideline (2021) recommends that children with ISS could be evaluated using targeted panel sequencing or WES. In commercial laboratories, WES is often performed and the genetic evaluation is offered as...
