Dr. John Mulliken studies the long-term outcomes of his patients with repaired cleft lip/palate. He collaborates with geneticists at the University of Texas on the molecular basis for non-syndromic cleft lip/palate. This research involves the genetic-sequencing of DNA from blood samples drawn from the parent and child. By pooling data from hundreds of families, the laboratory continues to locate genes that are likely responsible for common cleft lip/palate.
