If a patient has a genetic disorder, or suspects one, a doctor in this field is often good to see. Genetics is extremely complex and it is important that patients with these disorders get the most skilled care.

For example, a neurologist often treats those with epilepsy, as it is largely a neurological disorder. But this disorder also often runs in families, making it also hereditary in nature. A genetic specialist and a neurologist can work together to ensure the best and most comprehensive care for the patient.

Another example is a BRCA gene mutation. A genetic counselor and a molecular genetics specialist will work to determine whether the patient actually does have this gene. Once they've determined the patient is positive for this gene mutation, she will need to consult with other specialists, such as an OB/GYN, to determine whether surgery or other treatment options will lower her risk of breast, ovarian or other cancers associated with this gene. So, in this case, the genetic specialist initiates the patient's care and then refers her to the appropriate specialists, depending on the results of the testing.

A genetic specialist may also be necessary for patients with an undiagnosed illness. If the patient has been through testing with different specialists and still does not have a diagnosis, a genetic doctor may come in and help the other specialists determine whether the patient has a genetic disease or some type of genetic abnormality that could help the doctors give the patient the right diagnosis.
