LaSalud.mx.- September 20 marks the International Child Growth Awareness Day, one of its objectives is to sensitize the public and health professionals about the conditions, and the importance of knowing the rates of child growth.

More than 200 conditions are currently known to affect growth, including severe primary insulin-like growth factor I (IGF-1) deficiency. This is a very rare autosomal recessive situation, it occurs one in 1 million. It is characterized by a severe delay in the growth of children caused by the genetic inheritance of two copies of a mutated (changed) gene, one from the father and one from the mother. Because of this, low levels of IGF-1 (a hormone produced in the liver) occur.

Among the clinical and metabolic characteristics of those with this condition are: frontal protrusion, high voice, hypoplasia of the midface and nasal bridge, blue sclerae, scant hair, and hypoglycemia.

Rare diseases on many occasions can cause death or permanent disability, for this reason, their study and research is difficult, which causes deficient treatments.

It is important that parents record the growth of their children and go to periodic and comprehensive reviews with the pediatrician or treating doctor to determine if the child or adolescent requires a study to evaluate their development.
