DiGeorge syndrome is a genetic disorder caused by a chromosomal abnormality. This condition is characterized by a wide range of symptoms and presentations, which have led to various names being used in the past, such as Shprintzen syndrome, Velocardiofacial syndrome, and CATCH 22 syndrome. The impact of DiGeorge syndrome can vary greatly from one child to another, affecting different body systems to different extents. The management of this condition depends on the severity of symptoms and the specific systems affected, often involving surgical interventions and therapies.
Cause of DiGeorge Syndrome
DiGeorge syndrome is a genetic disorder that occurs due to a defect in chromosome 22. In individuals with this condition, a specific segment of chromosome 22 is missing. The prevalence of DiGeorge syndrome is estimated to be approximately one in 4,000 individuals. However, some experts believe that the actual number may be higher as some children may present with milder symptoms.
Understanding DiGeorge Syndrome
DiGeorge syndrome is a genetic disorder that affects individuals who inherit two copies of chromosome 22 from their parents. However, in this condition, one of these copies is missing an essential segment known as 11.2. This segment is crucial as it contains up to 40 genes that play a significant role in the body’s genetic makeup. The deletion of this segment can occur randomly, either during fertilization or early fetal development.
It is important to note that DiGeorge syndrome is rarely an inherited condition. Instead, it is typically caused by a sporadic deletion that happens by chance. This means that the syndrome is not passed down from parents to their children.
