Deletion syndrome is a disorder that involves many different areas of the body and can vary greatly in severity among people with the condition. Signs and symptoms may include: cleft palate, heart defects, recurrent infections, unique facial characteristics, feeding problems, kidney abnormalities, hypoparathyroidism, thrombocytopenia, scoliosis, hearing loss, developmental delay, and learning disabilities. People with this condition are also more likely to develop certain autoimmune disorders and personality disorders. 22q11.2 deletion syndrome is caused by a deletion of a small part of chromosome 22 near the middle of the chromosome at a location known as q11.2.
