The central research finding is that mutations in the gene AFF4 disrupt a crucial group of proteins called the super elongation complex (SEC). CHOPS Syndrome: Early Development Genetic Syndrome. But the discovery also became important for other reasons. Life tables can also be used to compare how life expectancy has improved or declined over time. CHOPS syndrome is a disorder involving multiple abnormalities that are present from birth (congenital). It allows us to find other children and adults with the same condition that in turn gives us a better understanding of the clinical issues and best options for management and to provide some idea of prognosis for families.
