چکیده
The DiGeorge Syndrome results from microdeletion in a small segment of the chromosome 22. When inherited from parents, it follows autosomal dominant patterns. There are variable clinical features related to the DiGeorge Syndrome. The most common ones are congenital heart diseases, thymic hypoplasia, learning difficulties, characteristic facial appearance, hypocalcaemia, and psychotic disorders later in adolescence.

Immunodeficiency in DiGeorge Syndrome and Options for Treating Cases with Complete Athymia
The commonest association of thymic stromal deficiency resulting in T-cell immunodeficiency is the DiGeorge syndrome (DGS). This results from abnormal development of the third and fourth pharyngeal arches and is most commonly associated with a microdeletion at chromosome 22q11 though other genetic and non-genetic causes have been described. The immunological competence of affected individuals i...
متن کاملComplete DiGeorge anomaly in the absence of neonatal hypocalcemia and velofacial and cardiac defects.
We report an atypical case of complete DiGeorge (DG) anomaly that presented initially exclusively as severe combined immunodeficiency (SCID). The child had severe infections at diagnosis, in keeping with the SCID phenotype; however, normal lymphocyte counts and immunoglobulin levels were noted at admission, which delayed diagnosis. Importantly, the child presented without neonatal hypocalcemia ...
متن کاملAtypical Omenn Syndrome Due to RAG2 Gene Mutation, a Case Report
Severe Combined Immunodeficiency (SCID), characterized by a profound decrease in both the number and function of T cells, is related to more than 20 different mutations. Recombination-activating gene (RAG) 1 and 2 seem to be two of the most common forms presenting with various manifestations, including typical SCID, Omenn syndrome (OS), atypical SCID (AS), or delayed onset combined immunodefici...
متن کاملSevere combined immunodeficiency presented with septic arthritis: A case report
Severe combined immunodeficiency is a rare, fatal syndrome of diverse genetic cause in which there is combined absence of T-lymphocyte and B-lymphocyte function (and in many cases also natural killer, or NK lymphocyte function). These defects lead to extreme susceptibility to serious infections. Without intervention, the T and B-cell dysfunction usually results in severe infection and death in ...
متن کاملDigeorge syndrome presenting with uncommon cardiac anomaly and hepatomegaly
Digeorge syndrome is caused by microdeletion of a large region of chromosome 22q11.2 lead to the abnormal development of the third and fourth pharyngeal pouches. This syndrome is characterized by hypoparathyroidism, cellular immune deficiency secondary to thymic hypoplasia, congenital heart disease and dysmorphic facial features. In this case report, we describe a 4month old boy who presented w...
