This may happen even earlier, especially if there is a period of rapid weight gain. Children may then enter puberty, which accelerates bone age even further. [rarediseases.org]
Features in “young” sporadic and familial cases indicating creatine deficiency are short stature, low weight gain and poor muscle build, hypotonia, movement disorder (extrapyramidal/spasticity), seizures, behavior and expressive language problems, and [latunisiemedicale.com]
Growth and puberty The mean birth weight was 2800 g (range 2000–3700 g), corresponding to the 3rd centile for gestation. Most parents described an exaggerated weight gain, particularly in the truncal region, in mid-childhood. [jmg.bmj.com]

There are two main types of clinical studies: Clinical trials determine if a new test or treatment for a disease is effective and safe by comparing groups receiving different tests/treatments. [rarediseases.info.nih.gov]
Make informed clinical choices for each patient, from diagnosis and treatment selection through post-treatment strategies and management of complications, with new evidence-based criteria throughout. [books.google.de]
With treatment, the condition can normally be completely cured. For some people, their condition settles down without needing treatment. [nhs.uk]
Treatment is usually given to help manage and improve the signs and symptoms. [dovemed.com]
