Getting Tested

How to Get Diagnosed

Getting diagnosed for CHD2 typically involves a combination of genetic testing, a review of medical history, a physical examination, a neurological examination, imaging studies and EEGs to support the diagnosis and understand the effects of the mutation. A blood sample is taken for genetic analysis to confirm the presence of a CHD2 mutation. It is important to note that the diagnosis can only be confirmed through genetic testing.

A pathogenic variant in the CHD2 gene is identified by genetic testing.
