My brother Luke, and I were diagnosed in 1991 at Children’s Hospital in Buffalo, New York, with a rare genetic disorder called Cockayne Syndrome (CS), a form of dwarfism. Cockayne Syndrome (CS), is an autosomal (affects both boys and girls)recessive disease (implies that inheriting two genes, one from each parent is required). CS type 1 or classic CS is the most common form in which the first year
of life is basically normal with the onset of symptoms in the second year of life. CS type 2 or early-onset CS, symptoms are displayed within the first year. A mild form of CS type 3 has been identified in which children have only a few characteristics. Cockayne Syndrome is also a leukodystrophy, which is a progressive disorder that affects the brain, and causes a loss of the myelin sheath that surrounds and protects nerve fibers.
