DiGeorge syndrome (DGS; also known as Velo-cardio-facial syndrome) is associated with hemizygous deletion of a region of human chromosome 22q11, causing a range of abnormalities including cardiovascular defects, hypoplasia of the thymus and parathyroid gland, and craniofacial abnormalities.Three research groups have identified the TBX1 gene, a member of the T-box family of transcription factors, as a key determinant of the DGS phenotype.
