DiGeorge syndrome is a genetic disorder caused by a microdeletion on chromosome 22. It can affect many parts of the body, including the face, heart, immune system, and brain. Learn about the characteristic facial features, such as hypertelorism, short palpebral fissures, and cleft palate, and other common symptoms of this syndrome.
The 22q11.2 deletion is one of the most common genetic microdeletions, affecting approximately 1 in 4000 live births in humans. A 1.5 to 2.5 Mb hemizygous deletion of chromosome 22q11.2 causes DiGeorge syndrome (DGS) and velocardiofacial syndrome ...

DiGeorge syndrome presents with distinct facial features, immune deficiencies, heart defects, and developmental delays due to a chromosome 22q11.2 deletion.
DiGeorge syndrome is a primary immunodeficiency disorder caused by the deletion of a small part of chromosome 22. This chromosomal deletion disrupts the development of multiple body systems, leading to a wide range of clinical symptoms. It is characterized by congenital heart defects, immunodeficiency, characteristic facial features, developmental delays, and metabolic abnormalities such as ...

Most patients with the clinical features of DiGeorge, velocardiofacial, and conotruncal anomaly face syndromes share a common genetic cause, namely, a deletion of chromosome 22q11, and define the most common deletion syndrome known at this time. The clinical features of the 22q11 deletion syndrome are highly variable between individuals; some have subtle findings, whereas others are severely ...

DiGeorge syndrome, also known as 'CATCH 22', is the most common deletion in humans and is one of the velocardiofacial syndromes. It is characterized by a specific facial phenotype, and structural and functional abnormalities in the cardiac and ...
The features associated with DGS result from dysmorphogenesis of the 3rd and 4th pharyngeal pouches during embryogenesis, leading to thymus or parathyroid gland hypoplasia or aplasia. Related anomalies involve structures forming around the same time, including the great vessels, esophagus, uvula, heart, facial, and ear anomalies. 4
DiGeorge syndrome, or 22q11.2 deletion syndrome, is a chromosomal disorder affecting the 22nd chromosome, leading to various developmental and health issues, including congenital heart defects and behavioral problems. Approximately 90% of cases result from a deletion at the 22q11.2 locus, with symptoms ranging from specific facial features to learning disabilities. Diagnosis is typically made ...
Velocardiofacial syndrome, DiGeorge syndrome, and some other clinical syndromes have in common a high frequency of hemizygous deletions of chromosome 22q11.2. This deletion syndrome is very common, affecting nearly one in 3000 children. Here, we focus on recent advances in cardiac assessment, speech, immunology, and pathophysiology of velocardiofacial syndrome. The complex medical care of ...
DiGeorge syndrome was first described in 1968 as a rare developmental field defect affecting structures derived from the third and fourth embryonic pharyngeal arches [1,2]. Characteristic features included distinct facial features, hypoplasia or aplasia of the thymus, hypoplasia or aplasia of the parathyroid glands, and conotruncal cardiac defects. Infants presented with hypocalcemia ...
Chromosome 22q11.2 deletion syndrome (22qDS) includes DGS and other similar syndromes, such as velocardiofacial syndrome. The classic triad of features of DGS on presentation is conotruncal cardiac anomalies, hypoplastic thymus, and hypocalcemia (resulting from parathyroid hypoplasia). Thymic defects in DGS result in a range of T cell deficits.
DiGeorge syndrome DiGeorge syndrome is characterized by classical facial features and defects of the heart, parathyroid glands, and thymus [70]. Although DiGeorge syndrome often is grouped with the 22q11.2 deletion syndrome, only approximately 90% of the patients have this anomaly [71]. Defects in the thymus result in variable degrees of immunodeficiency. Those who have below-normal T-cell ...

What is DiGeorge Syndrome? DiGeorge syndrome is a genetic condition where a small part of chromosome 22 is missing. A patient with DiGeorge syndrome is missing a segment in one copy of chromosome 22 at a location called q11.2 (22q11.2 deletion syndrome). The deletion can involve many genes that are close together. The signs and symptoms vary depending on the number of genes lost. Depending on ...
The 22q11.2 deletion is one of the most common genetic microdeletions, affecting approximately 1 in 4000 live births in humans. A 1.5 to 2.5 Mb hemizygous deletion of chromosome 22q11.2 causes DiGeorge syndrome (DGS) and velocardiofacial syndrome (VCFS). DGS/VCFS are associated with prevalent cardiac malformations, thymic and parathyroid hypoplasia, and craniofacial defects. Patients with DGS ...

DiGeorge syndrome, also known as 22q11.2 deletion syndrome, is a syndrome caused by the deletion of a small segment of chromosome 22. [7] While the symptoms can vary, they often include congenital heart problems, specific facial features, frequent infections, developmental delay, learning problems and cleft palate. [7]
The term 22q11.2 deletion syndrome covers terms once thought to be different conditions. These terms include DiGeorge syndrome, velocardiofacial (vel-oh-cahr-dee-oh-fay-shell) syndrome and other conditions caused by the same missing part of chromosome 22. But features may vary slightly.
Symptoms of DiGeorge syndrome may include: Heart issues, such as problems with the structure of the heart and vessels, or a heart murmur and bluish skin because of poor circulation of blood, also known as cyanosis. Frequent infections. Distinctive facial features, such as an underdeveloped chin, ears that look different, wide-set eyes, hooded eyes and an enlarged nose tip. Asymmetric crying ...
DiGeorge syndrome symptoms Facial anomalies - underdeveloped chin, ears rotated back, and big eyelids. Cardiac issues - It affects the aortic chamber of the heart. People with DiGeorge syndrome have a mild heart defect. abnormalities of the thymus gland - The thymus gland plays an important role in the development of the immune system.
What are the main symptoms of 22q11.2 Deletion syndrome? 22q11.2 deletion syndrome and DiGeorge syndrome represent a spectrum of syndromes that share congenital heart defects, immunological abnormalities, and variable facial features. The main symptoms of 22q11.2 deletion syndrome can vary significantly between individuals.

People with complete DiGeorge syndrome have no thymus or parathyroid glands. Risk Factors Maternal diabetes is thought to ...
DiGeorge syndrome is a rare congenital (i.e. present at birth) disease whose symptoms vary greatly between individuals but commonly include a history of recurrent infection, heart defects, and characteristic facial features.
Digeorge Syndrome: Per Mayo Clinic facial features may include "small, low-set ears, short width of eye openings (palpebral fissures), hooded eyes, a relatively long face, an enlarged nose tip (bulbous), or a short or flattened groove in the upper lip." cleft palate w or w/o cleft lip can occur. There may be few or many of these features.
