What is the life expectancy for Cockayne syndrome?
People with this type of Cockayne syndrome live into adulthood, with an average lifespan of 40 to 50 years.
What causes Cockayne syndrome?
Cockayne syndrome can result from mutations in either the ERCC6 gene (also known as CSB) or the ERCC8 gene (also known as CSA). These genes provide instructions for making proteins that are involved in repairing damaged DNA .
When was Cockayne syndrome discovered?
Cockayne syndrome (CS) is a rare, autosomal-recessive disorder that was first described in 1936 by Edward Cockayne. Early descriptions of CS identified the cardinal clinical features of the disorder: microcephaly and growth failure.
