For patients
What this test and program do
If you or your child developed cataracts in both eyes at a young age, there may be a genetic reason, and finding out could change how the condition is managed. The Scout program provides no-cost genetic testing that looks at 66 genes connected to inherited cataracts, including metabolic causes like cerebrotendinous xanthomatosis (CTX) that may benefit from early treatment. The program is sponsored by Mirum Pharmaceuticals and performed by Prevention Genetics, so there is no bill sent to you or your insurance. Your doctor can determine whether you qualify and take care of the entire process.

FAQ
Common questions about this program
What is the Scout genetic testing program for early-onset bilateral cataracts?
The Scout program is a sponsored genetic testing program designed for people who developed cataracts in both eyes early in life. It uses a 66-gene panel to look for inherited causes of bilateral cataracts, including metabolic conditions such as CTX. The test is performed by Prevention Genetics and is available to eligible patients in the United States at no cost.
Is the Scout bilateral cataracts genetic test really free, and who pays for it?
Yes, the Scout program is completely free to you. Mirum Pharmaceuticals sponsors the program and covers the full cost of testing, so you will not receive a bill, a copay, or any charge. Your only step is to work with your doctor, who will determine if you meet the program's criteria and coordinate everything.
What kind of sample is needed for the Scout early-onset bilateral cataracts test?
The Scout program accepts either a simple blood draw or a buccal swab, which involves gently rubbing the inside of the cheek. Your doctor's office will order a free sample collection kit and let you know which option works best for your situation. Neither method requires any special preparation.
How long does it take to get results from the Scout bilateral cataracts genetic test?
Results from the Scout early-onset bilateral cataracts panel are typically returned within 2 to 3 weeks after the lab receives your sample. Your ordering provider will review the results with you and explain what they mean for your care or your child's care.
Why does genetic testing matter if I already know I have bilateral cataracts?
Even when cataracts have already been diagnosed, genetic testing through the Scout program can reveal the underlying cause, which may affect how your condition is managed going forward. For example, the 66-gene panel checks for metabolic disorders like CTX that can be treated more effectively when caught early. Understanding the genetic basis can also provide important information for family members who may be at risk.
Will I receive genetic counseling with the Scout cataracts testing program?
Your ordering provider oversees the entire testing process, including helping you understand your results. If you have questions about what a genetic finding means for you or your family, your doctor can connect you with a genetic counselor or other specialist who can walk you through the details.
Who qualifies for Scout Early-Onset Bilateral Cataracts genetic testing?
Patients may qualify for Scout if they meet the program's eligibility criteria:
- You must be 18 months to 35 years old.
- You may qualify if you have current or past bilateral cataracts that do not have a known cause such as infection or trauma.
- You must live in the United States.
