A Butterfly Walk for Hannah Crego, a fourth grader at Fairley Elementary School, will be held April 28 at 1 p.m at the Hannibal Central School Track.
Crego has Cockayne Syndrome, or CS, a rare genetic disorder characterized by poor growth, premature aging, sensitivity to sunlight, moderate to profound developmental and neurological delays and a shortened lifespan.
Crego, who will turn 12 in August, appeared to be an average little girl until the age four. It wasn’t until the age of eight and trips to see geneticists and specialists at the Cleveland Clinic in Ohio, Rochester and Boston, that Crego was diagnosed with CS type 2. CS type 1 presents at birth.
Cockayne syndrome type 2 appears during early childhood. Crego’s local physician, Dr. Stuart Trust had never seen a case like hers.
Cockayne syndrome is very rare, and in Hannah’s case, one in a million. In order for a child to be affected by CS, he or she must inherit a mutation in the same CS gene from both parents.
Hannah’s parents Jennifer and Jason Crego of Martville are both carriers of a single CS gene. A couple has a one in four chance of having another child with CS. Their son, and Hannah’s brother Nathan, does not exhibit any symptoms of the syndrome.
