What is the cleft lip and palate study?
The purpose of this research study is to identify the genes and environmental factors causing isolated cleft lip and palate. We are collecting information about pregnancy specific exposures and obtaining blood samples from which DNA (genetic material) will be made. We will use the DNA to determine whether specific genes are associated with cleft lip and palate. We will also correlate whether specific types of exposures are linked to cleft lip and palate.
