Most people are familiar with disorders like Autism, Down syndrome or ADHD, but there's a chromosome-based disorder out there so rare it doesn't even have a name and leaves kids looking like toddlers for the rest of their lives.
Tandy Palmes's son Angus is thought to be the only child in the world affected by this strange disorder, which caused him to stop growing at the age of three, so she went on This Morning to discuss the disorder:
Tandy explained to presenters Sarah Greene and Rylan Clark-Neal that doctors were concerned about his health after he was born, and sent him for testing to get to the bottom of things
"We had no idea there was anything wrong, although they had their suspicions," Tandy said.
"They took us in an ambulance to one of the Manchester hospitals and did some genetic tests and three weeks after that they told me they found this chromosome abnormality by accident."
The condition means that Angus, who is 13 years old, remains in the body of a toddler after he stopped growing when he was just three.
