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 ]
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.
22q13 deletion syndrome, known as Phelan–McDermid syndrome (PMS), is a genetic disorder caused by deletions or rearrangements on the q terminal end (long arm) of chromosome 22. Any abnormal genetic variation in the q13 region that presents with significant manifestations ( phenotype ) typical of a terminal deletion may be diagnosed as 22q13 ...
22q11.2 deletion syndrome: Most people with 22q11.2 deletion syndrome are missing about 3 million base pairs on one copy of chromosome 22 in each cell. The deletion occurs near the middle of the chromosome at a location designated as q11.2. This region contains about 30 genes, but many of these genes have not been well characterized.
Collins had 22q deletion syndrome, also known as DiGeorge syndrome, the second-most common genetic disorder behind Down’s syndrome, according to the International 22q11.3 Foundation.Her family ...
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 ...
