Cornelia de Lange Syndrome is a rare congenital malformation syndrome with typical craniofacial abnormalities and can affect the musculoskeletal, cardiovascular, gastrointestinal, genitourinary, and central nervous systems. Not all the patients look alike as the phenotypic appearance is seen on a spectrum. A classic case of CdLS has been reviewed in this article and we have discussed diagnosis, management, and anticipatory guidance. Maintaining consistent health supervision visits and outpatient therapy is vital for these children. Referring the parents to a genetic counselor is recommended if the family desires to have more children. The CdLS foundation Webpage is www.cdlsusa.org.
