This is usually identified by a blood test called a FISH analysis (for Fluorescent In Situ Hybridization). [31] Of the 3050 genes in the deleted region, a number have been identified as possibly playing a role in the development of some of the signs and symptoms. A small deletion on chromosome 22 causes the syndrome. For example, your child may be born with a cleft palate or other facial characteristics, such as a recessed jaw, flat cheeks, or a tubular nose. DiGeorge Syndrome is a primary immunodeficiency disease caused by abnormal migration and development of certain cells and tissues during fetal development. If there is a problem with the T-cells, precautions must be taken as with other children with congenital T-cell immunodeficiencies. In most cases, the causes of the syndrome are simply unknown. This may be due in part to structural differences such as a cleft palate (a hole in the roof of the mouth) or to functional difficulties (either VPI or oral apraxia). [7] Diagnosis is suspected based on the symptoms and confirmed by genetic testing. BY. [7] The syndrome was first described in 1968 by American physician Angelo DiGeorge.

Specifically, a piece of chromosome 22 is missing in individuals with DiGeorge syndrome. These original classifications included velocardiofacial syndrome, Shprintzen syndrome, DiGeorge sequence/syndrome, Sedlackova syndrome, and conotruncal anomaly face syndrome. The gene is autosomal dominant, meaning each child born to a person with the gene has a 50% chance of receiving the gene and manifesting the syndrome. When part of this chromosome is missing, related organs and systems dont develop normally. [19], Children with DiGeorge syndrome have a specific profile in neuropsychological tests. Click to Join.

Spotting issues early can enable you and your provider to prepare for your babys care after birth. Symptoms vary from person to person with DiGeorge syndrome. [56][57] This estimate is based on major birth defects and may be an underestimate, because some individuals with the deletion have few symptoms and may not have been formally diagnosed. Whats more likely (in 90 percent of cases) is that the deletion happens at random when the sperm meets the egg. The neural crest forms many of the structures affected in DiGeorge syndrome, including the skull bones, mesenchyme of the face and palate, the outflow tract of the heart, and the thymus and parathyroid stroma.
