As CHARGE Syndrome was only identified in 1981, there are people who are living their lives undiagnosed. We do not know how many people there are across Australia and New Zealand with CHARGE Syndrome. How many people with CHARGE syndrome are there in Australia/New Zealand? Always confirm the information relevant to your family with your medical geneticist or genetic counsellor. People in the family with the same CHD7 change, may or may not have similar features. Īn individual with CHARGE syndrome, has a 50% chance of having a baby with CHARGE. Read more about recurrence risks on The CHARGE Foundation website. Always confirm the information relevant to your family, with your medical geneticist or genetic counsellor. The CHARGE Syndrome Foundation website states that “Based on the experience of thousands of families, the recurrence risk is 1-2% on average.” However, if a parent tests positive for the CHD7 change detected in the affected child, there is a 50% chance of passing on the gene to another baby. Although individuals with CHARGE may remain medically fragile, they are able to adapt and lead productive and fulfilling lives. In the first few years there is an increased risk of serious medical issues. What is the life expectancy for people with CHARGE syndrome? Professionals with an understanding of the challenges will be able to identify the most effective interventions to support positive outcomes. Intelligence in children with CHARGE is often difficult to measure and underestimated due to the impact of multi-sensory impairment and other developmental challenges. How does CHARGE syndrome affect cognitive abilities? With these supports in place individuals with CHARGE have every opportunity to reach their developmental potential. In addition, early intervention and appropriate educational and vocational programs specific to their developmental needs, are essential. Individuals with CHARGE need medical care appropriate to their particular features. The range of outcomes in individuals with CHARGE is as broad as it could possibly be. What are the expected outcomes likely to be? Read more about diagnosis and testing on The CHARGE Syndrome Foundation website. CHARGE syndrome is still diagnosed by a medical geneticist primarily based on clinical features. On the other hand, if a CHD7 change is not identified, it does not rule out CHARGE syndrome. If a change in CHD7 is identified in a child with CHARGE syndrome features, then the diagnosis is confirmed. However, it does not always provide answers. CHD7 gene testing can be ordered (by itself or as part of a panel of genes) and the test takes several weeks to be completed. More than 80% of children with CHARGE have identifiable changes in the CHD7 gene. Is there a test to confirm CHARGE syndrome? CHARGE syndrome does not usually affect other members of a family and it is not caused by any known exposures during pregnancy.
Most of the time, the CHD7 change happened only in the one sperm or egg that formed your child with CHARGE syndrome. Major characteristicsįor more information about each of these features, visit the Signs & Symptoms page of the CHARGE Foundation website.ĬHARGE syndrome is caused by a change in the gene CHD7. In 1998, Dr Kim Blake and colleagues reclassified the major and minor characteristics of CHARGE syndrome.
What are the features of CHARGE syndrome?
