About this trial
Retrospective, single-centre, non-profit, observational study on pubertal development in patients with RASopathies.
Literature data shows that puberty can be delayed by about 2 years in patients with RASopathies and this has been associated with a reduced peak growth rate. To date, only a few numerically limited case series without molecular characterisation have been published.
This descriptive study should improve knowledge of pubertal development and its influence on growth and final stature. The primary aims are to describe the age of onset and progression of pubertal development in the cohort of patients with RASopathies, both male and female, and to describe the influence of pubertal development on statural growth and final stature in the same cohort.
