DiGeorge syndrome, also known as 22q11.2 deletion syndrome, is a syndrome caused by a microdeletion on the long arm of chromosome 22. [7] While the symptoms can vary, they often include congenital heart problems , specific facial features, frequent infections, developmental disability , intellectual disability and cleft palate . [ 7 ]
Thymus transplantation is used to treat infants with DiGeorge syndrome, which results in an absent or hypoplastic thymus, in turn causing problems with the immune system's T-cell mediated response. It is used in people with complete DiGeorge anomaly, which are entirely athymic. This subgroup represents less than 1% of DiGeorge syndrome patients ...
22q11.2 distal deletion syndrome is a rare genetic condition caused by a tiny missing part of one of the body's 46 chromosomes – chromosome 22. 22q11.2 distal deletion syndrome appears to be a recurrent genomic disorder distinct from 22q11.2 deletion syndrome also known as DiGeorge syndrome (DGS; 188400) and velocardiofacial syndrome (VCFS; 192430).
Alright as a quick recap, DiGeorge syndrome or 22q11.2 deletion syndrome, is a genetic condition where the q11.2 portion of DNA on chromosome 22 is deleted, which can cause developmental issues like thymic and parathyroid hypoplasia, congenital heart defects, facial abnormalities, mental health conditions, and others.
A significant T cell deficiency, recurrent infections, susceptibility to opportunistic infections, and a tendency to develop autologous graft-versus-host disease (GVHD) or, in the case of complete DiGeorge syndrome, a "atypical" phenotype are characteristics of congenital athymia. [3] [4]
Curative treatment consists of open heart surgery soon after birth, preferably immediately after diagnosis. [2] Often, a synthetic patch is used to recreate the lost section of aorta. [ 2 ] Recent research has revealed that an initial single-stage repair using direct anastomoses and repair of any existing cardiac defects is the preferred ...
This condition is identified when a band in the q11.2 section of the arm of chromosome 22 is missing or deleted. This condition has several different names: 22q11.2 deletion syndrome, velocardiofacial syndrome, DiGeorge syndrome, conotruncal anomaly face syndrome, Opitz G/BBB syndrome, and Cayler cardiofacial syndrome.
Genetic factors linked to TOF include various gene mutations or deletions. Gene deletions associated with TOF include chromosome 22 deletion as well as DiGeorge syndrome. [24] Specific genes associations with TOF include: JAG1 codes for ligands within the Notch family of proteins and is highly expressed in the developing heart. [25]
