There are close to 750 congenital anomalies identified with an ICD-9 code. A non-comprehensive list can be found here: Congenital Anomalies (Links to an external site.). Each person in your group will pick a different anomaly and explore the structure of the body that is affected, the chromosome, and gene to share with the rest of the group.  What type of mutation to the gene causes this anomaly?  Is there more than one type of known mutation? If so, be sure to include them.  Also, include the symptoms and treatment options for an infant born with this anomaly.  What is the prognosis in most cases?
