DiGeorge syndrome is characterized by a range of symptoms resulting from a deletion of a small segment of chromosome 22. One of the hallmark features of this condition is the presence of congenital heart disease, specifically conotruncal anomalies such as tetralogy of Fallot or truncus arteriosus. This association demonstrates how the chromosomal abnormality impacts cardiovascular development, leading to structural heart defects.

While the other options may represent symptoms or conditions found in various syndromes or disorders, they are not specifically linked to DiGeorge syndrome. An enlarged thyroid gland is typically related to conditions like goiter or autoimmune diseases, excessive sweating can be seen in a variety of clinical settings including hormonal disorders, and a persistent cough may be indicative of respiratory infections or chronic lung conditions, but none of these are defining characteristics of DiGeorge syndrome. The connection between congenital heart disease and DiGeorge syndrome underscores the importance of genetic evaluation in patients presenting with heart anomalies and related health issues.
