To understand this process, it can be helpful to think of the thymus as a schoolhouse. The gene coding for C22orf25 is located on chromosome 22 and the location q11.21, so it is often associated with 22q11.2 deletion syndrome. DiGeorge syndrome, more accurately known by a broader term 22q11.2 deletion syndrome is a disorder caused when a small part of chromosome 22 is missing.

Some infants who do not have a thymus or have an underdeveloped thymus have mothers who are diabetic. By definition, complete DiGeorge syndrome is characterized by absence or underdevelopment (hypoplasia) of the thymus resulting in very low T cell counts. The researchers studied the clinical information of 106 participants and photographs of 101 participants with the disease from 11 countries in Africa, Asia and Latin America.
