Understanding Your Results
Normal
Clinical action: No increased risk of Huntington's disease. No medical action needed.
Intermediate
Clinical action: The individual will not develop HD but the allele may expand in offspring; genetic counseling is advised.
Reduced Penetrance
Clinical action: There is a risk of developing HD; regular neurological follow-up and genetic counseling recommended.
Full Penetrance
Clinical action: The individual will develop Huntington's disease within their lifetime. Refer to a neurologist and genetic counselor for management and family planning.
If you have a parent or sibling with Huntington's disease, or if you experience symptoms such as uncontrolled movements, mood changes, or difficulty thinking without other cause, consult a neurologist or medical geneticist for genetic testing.
