This study included 25 children diagnosed with CHARGE syndrome with positive CHD7 mutations through the Children's Hospital of Philadelphia genetics program. The overwhelming majority of children with VCF have a microdeletion (tiny missing piece) of chromosome 22 (deletion 22q11.2) which can also be detected by a special lab technique called FISH (fluorescent in-situ hybridization) or chromosomal microarray (which is a broader test which shows the size of the deletion and detects other chromosomal abnormalities too).

Some children with CHARGE appear to have poor immune responses to infections. Husu E, Hove HD, Farholt S, et al. In many cases, the external ear can be unique enough to suspect the diagnosis of CHARGE before examining other features, and a temporal bone CT scan to look for absent semicircular canals and evaluate the choanae for atresia or stenosis should prompt mutation analysis of CHD7 to confirm the diagnosis. CHARGE stands for coloboma, heart defect, atresia choanae (also known as choanal atresia), restricted growth and development, genital abnormality, and ear abnormality.

Affected individuals frequently have hypogonadotropic hypogonadism, which affects the production of hormones that direct sexual development. Symptoms may start to appearas a Newborn. In rare cases, CHARGE has run in families, either two affected children or a parent and child affected, either because of parental mosaicism for a CHD7 mutation, which results in a parent being mildly affected or not affected at all.
