The chances of a person with DiGeorge syndrome having an affected child is 50% for each pregnancy; (2) Parents who have affected children, but who were unaware of their own genetic conditions, are now being diagnosed as genetic testing become available; (3) Molecular genetics techniques such as FISH (fluorescence in situ hybridization) have limitations and have not been able to detect all 22q11.2 deletions. In a small number of cases, DiGeorge syndrome is hereditary (passed from a parent to a child). We do not endorse non-Cleveland Clinic products or services. DiGeorge syndrome occurs in about 1 in 4,000 people. These genes include the FOXN1, TBX1, TBX2, and the PAX1 genes. 1. Feeding problems due to cleft lip or palate.

In some patients with DGS, the T-lymphocyte defect is significant enough to cause the B-lymphocytes to fail to make sufficient antibodies. In such instances, the infants are kept in isolation right away. As part of the developmental defect, the thymus gland may be affected and T-lymphocyte production may be impaired, resulting in low T-lymphocyte numbers and frequent infections.
