![]() ![]() Changes in gene expression during embryonic development likely cause the signs and symptoms of CHARGE SyndromeĪbout one-third of individuals with CHARGE Syndrome do not have an identified mutation in the CHD7 gene. ![]() ![]() Most mutations in the CHD7 gene lead to the production of an abnormally short, nonfunctional CHD7 protein, which is thought to disrupt the regulation of gene expression.The CHD7 gene provides instructions for making a protein that most likely regulates gene activity (expression).However, autosomal dominant inheritance with transmission from parent to child has been reported in rare cases.Almost all mutations in affected individuals are de novo, which means they occur for the first time as new mutations and are not inherited from a parent.What are the Causes of CHARGE Syndrome? (Etiology)ĬHARGE Syndrome is caused by mutations in the CHD7 gene in the majority of cases. It is always important to discuss the effect of risk factors with your healthcare provider. Some risk factors are more important than others.Īlso, not having a risk factor does not mean that an individual will not get the condition. A risk factor increases one’s chances of getting a condition compared to an individual without the risk factors. It is important to note that having a risk factor does not mean that one will get the condition. Currently, no other risk factors have been clearly identified for the syndrome.A positive family history may be an important risk factor, since CHARGE Syndrome is an inherited condition.What are the Risk Factors for CHARGE Syndrome? (Predisposing Factors) Worldwide, individuals of all racial and ethnic groups may be affected.The presentation of symptoms may occur at birth CHARGE Syndrome is a rare, congenital disorder.(Source: CHARGE Syndrome Genetic and Rare Diseases Information Center (GARD) of National Center for Advancing Translational Sciences (NCATS), USA.) Who gets CHARGE Syndrome? (Age and Sex Distribution) A team of doctors is often needed to figure out the treatment options for each person Although there is no specific treatment or cure, there may be ways to manage the symptoms.When caused by a mutation in the CHD7 gene, it can be inherited in an autosomal dominant pattern although most cases result from new (de novo) mutations in the gene and occur in people with no history of the condition in their family.In more than half of all cases, mutations in the CHD7 gene cause CHARGE Syndrome The diagnosis of CHARGE Syndrome is based on a combination of major and minor characteristics.Signs and symptoms vary among people with this condition however, infants often have multiple life-threatening medical conditions.CHARGE stands for Coloboma, Heart defect, Atresia choanae (also known as choanal atresia), Restricted growth and development, Genital abnormality, and Ear abnormality CHARGE Syndrome is a congenital condition (present from birth) that affects many areas of the body.What is CHARGE Syndrome?
