Benefits of Impact’s Retinoblastoma Genetic Test

Unilateral Retinoblastoma

1. Risk of additional cancers
Genetic testing is the only way to determine whether additional tumors are likely to grow in the same and/or other eye. If tumor is available for testing, results are most precise. Without tumor, there is a 4% risk of missing the mutation.

2. Future cancer surveillance
If the genetic mutations of a tumor (retinoblastoma or second cancer) are known, a highly sensitive test may be used to monitor for spread of cancer.

3. Family
Knowing the disease causing genetic mutation in the patient makes it possible to look for the same mutation in family members. Surveillance and treatment of family members is improved if we know whether they carry the mutation.

Bilateral Retinoblastoma

1. Family
Knowing the disease causing genetic mutation in the patient makes it possible to look for the same mutation in family members. Surveillance and treatment of family members is improved if we know whether they carry the mutation.

2. Future cancer surveillance
If the genetic mutations of a tumor (retinoblastoma or second cancer) are known, a highly sensitive test may be used to monitor for spread of cancer.
