Natural history study of growth in children with type II collagen disorders
Part of Bones, joints & muscles, Genetic & congenital, Hormones & metabolism, Skin clinical trials.
This study follows children with certain inherited “type II collagen” conditions that cause short height, to better understand how growth changes over time. It does not test a new treatment; it mainly tracks health and growth so doctors can learn what to expect.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Child has a confirmed type II collagen disorder that causes short stature (such as Kniest, SEDc, SEMD, SED, or hypochondrogenesis)
- Child is younger than 13 years old at the time of consent/assent
- Parent/guardian can sign consent, and the child can give assent if required
- Child can attend scheduled study visits and follow study instructions
- No other non–type II-collagen cause of short height
- Not using growth-related medicines in the last 12 months (growth hormone, IGF-1, anabolic steroids, or similar)

This study is for children with hypochondroplasia, a condition that causes short stature. It will look at how the condition changes over time and aims to better understand it, with the goal of finding new treatments.
this study is a long-term extension of the main study for the drug which from Bio? bi? whatever? in the name? by?...????
This trial tests a new medicine for children with achondroplasia (a common form of dwarfism). It aims to see if the drug can improve growth. The study is for children aged 2.5 to under 11 years old who have not started puberty and can walk without help.
This study looks at your child’s growth history and performs genetic testing to better understand why some children are very short. It may help researchers identify possible underlying causes and improve care, using blood samples from the child and both parents.
This study tests whether an investigational drug can help children with idiopathic short stature (short height with no known cause) grow taller. It may be an option for children who are very short for their age and have not responded well to standard growth hormone therapy.
This study observes children with hypochondroplasia to learn more about the condition. It does not involve any treatment—just monitoring and data collection to help future research.
