19-year-old Broc Brown from Michigan is already a record breaking 7ft 8 inches.

But he's still growing at a rate of 6 inches a year - which could see him achieve his ambition of overtaking the current world record. That's held by Sultan Kosen who is 8ft 2 inches.

His incredible growth is due to Sotos Syndrome which he was diagnosed with at the age of five - by which time he was already 5ft 2 inches.

Broc and his mother Darci spoke with Emma Barnett about the challenges of living with the syndrome.
