This can happen by chance when sperm and eggs are made. It is not a result of anything you did before or during the pregnancy. In these cases, there's usually no family history of DiGeorge syndrome and the risk of it happening again to other children is very small. This applies to each pregnancy. Speak to a GP if you're planning a pregnancy and you have a family history of DiGeorge syndrome, or you have a child with it.
They may refer you for a genetic test and talk about your level of risk and discuss your options. These may include:. There's currently no cure for DiGeorge syndrome. Children and adults with the condition will be closely monitored to check for problems, and these can be treated as they happen, if needed.
You may find it useful to speak to a social worker, psychologist or counsellor, who you can contact directly or through a doctor. Charities such as Max Appeal!
Read more advice about caring for a disabled child. Everyone with DiGeorge syndrome is affected differently and it's difficult to predict how severe the condition will be. The syndrome usually starts as a random event during fertilization, either on the maternal or paternal side.
It may happen during the time of fetal development. However, in around 10 percent of cases, it is passed from a parent to a child. If a child has DiGeorge syndrome, parents or caregivers may notice that they have:. They include :. Other symptoms may include hearing impairment , visual abnormalities, and altered kidney function. Due to the significant variability of DiGeorge syndrome, the type and severity of symptoms are typically determined by the organ system affected. DiGeorge syndrome can become evident at birth, in infancy or during early childhood.
A health care provider is likely to request a FISH analysis if a child has symptoms that may indicate DiGeorge syndrome, or if there are signs of a heart defect. Certain types of heart defect are strongly associated with the condition. Treatment depends on the organ systems involved. It can involve a wide range of health professionals. Treatment includes supplementation with vitamin D or calcium and with parathyroid hormone. Treatment and vaccine scheduling is usually the same as for children without the condition.
The immune function usually becomes stonger as the child gets older. Severe thymus dysfunction poses a risk of severe infection. Thymus tissue transplantation, bone marrow transplant, stem cell transplant, or transplant of disease-fighting blood cells may be necessary.
Currently, there is no cure for DiGeorge syndrome, and it is a lifelong condition. Genetic counselors are important in this process in order to fully inform families of their options prior to conception.
One alternative is preimplantation genetic diagnosis PGD. PGD makes it possible for us to analyze embryos for specific genetic disorders [14]. This process involves in vitro fertilization, and can therefore be quite costly and has limited availability. The proband was a year-old female with no clinical symptoms of DiGeorge Syndrome, but did present with the classic facial features.
She received her diagnosis after the birth of a severely affected child, with a 22q None of the three PGD attempts resulted in a pregnancy in this case [15]. In , Shefi et al reported a successful PGD in a year-old woman with DiGeorge syndrome, with typical facial features and velopharyngeal anomaly.
She has a 3-year-old daughter who was diagnosed with DiGeorge syndrome shortly after birth.
