What Does NxGen MDx Screen For?

Neuronal Ceroid Lipofuscinosis, CLN3-Related

What Your Test Results Mean:

Test results indicate that you are a carrier of neuronal ceroid lipofuscinosis, CLN3-related. Carriers typically show no symptoms. You and your partner would both have to be carriers of neuronal ceroid lipofuscinosis, CLN3-related for there to be an increased chance to have a child with symptoms; this is known as autosomal recessive inheritance. Carrier testing of your partner or donor is recommended in addition to consultation with a genetic counselor for a more detailed risk assessment.

Since this is an inherited gene change, this information may be helpful to share with family members as it may impact their family planning and their own personal clinical management.

Neuronal ceroid lipofuscinosis, CLN3-related typically causes blindness and leads to early death. Symptoms begin between the ages of four and 10, usually with vision loss, progressing to seizures, developmental delays, muscle stiffness, and behavioral and psychiatric symptoms, such as attention deficits and aggression.


Prognosis is generally unfavorable. Neuronal ceroid lipofuscinosis, CLN3-related causes blindness and progressive loss of mental and motor functions. Death usually occurs in the late teens to twenties. Some people with the disease have lived into their thirties.
