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 ]
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.
22q11 microduplication syndrome [3] is the opposite of the 22q11 deletion syndrome; in this condition, a band of q.11.2 section of chromosome 22 is duplicated. Individuals carrying this deficiency are relatively "normal", as in they do not possess any major birth defects or major medical illnesses.
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 ...

The majority of 22q11 duplications are inherited often from a parent with a normal or near-normal phenotype. This is in sharp distinction to 22q11 deletion syndrome where about 90% of cases are caused by mutations that occur de novo. [citation needed] Genetic testing . Blood samples
