Some are able to attend mainstream schools, while others are home-schooled or in special classes. Surgery can be performed before any immune defects are corrected. DiGeorge syndrome is a condition present from birth that can cause a range of lifelong problems, including heart defects and learning difficulties. [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. [19], Children with DiGeorge syndrome have a specific profile in neuropsychological tests. [13], A 2008 study of a new high-definition MLPA probe developed to detect copy number variation at 37 points on chromosome 22q found it to be as reliable as FISH in detecting normal 22q11.2 deletions.
