As the child grows older, intellectual disability and learning differences are likely to become more obvious. Antibiotic medications to treat infections. Although neither FGF18 or TBX1 are expressed in the neural crest cells, TBX1 might have a role in the regulation of FGF18 expression, ensuring that the differentiation of these cells in the pharyngeal region is correct. Combating the loss of immune system T-cells is more challenging, though some children have benefited from a thymus transplant. Other complications of DiGeorge syndrome may include: You cant prevent DiGeorge syndrome. This means that a small portion of chromosome 22 is missing. Some individuals with DiGeorge Syndrome are nearly asymptomatic while others are affected more severely. Genetic analysis is normally performed using fluorescence in situ hybridization (FISH), which is able to detect microdeletions that standard karyotyping (e.g. School-age children do make progress with expressive language as they mature, but many continue to have delays and demonstrate difficulty when presented with language tasks such as verbally recalling narratives and producing longer and more complex sentences.
