Blandford boy 'only one' with genetic disorder

A two-year-old boy from Dorset is thought to be the only person in the world diagnosed with a rare genetic disorder.

Lewis Preuss, from Blandford, was inexplicably born missing part of chromosome number eight.

As a result he suffers from a range of medical and developmental problems.

Every day is a learning curve for his parents, who are hoping to raise awareness of such conditions.

South Today's Jo Kent has been to meet the family.
