22q11.2 deletion syndrome is a spectrum disorder encompassing what was formerly called DiGeorge syndrome, velocardiofacial syndrome, conotruncal anomaly face syndrome, and cases of Opitz G/BBB syndrome, and Cayler cardiofacial syndrome. It is characterized by a variety of symptoms, including cleft palate, heart defects, unique facial characteristics, learning and feeding problems, immune system disorders, hypoparathyroidism, and scoliosis. Symptoms can vary greatly from patient to patient. It is caused by a missing piece (deletion) of chromosome 22. The deletion occurs near the middle of the chromosome at a location designated q11.2.
