The Genetic Test You Received

• Comprehensive MELARIS ^®: Full sequence analysis of the p16 gene.
  

Your Test Result

• Genetic Variant of Uncertain Significance

Overview of Your Test Result

Mutations in the p16 gene are the most common known cause of hereditary melanoma syndrome.

• A change was detected in the p16 gene but it is not known if this change is linked to cancer.
• This change is called a genetic variant of uncertain significance.
• Ongoing efforts to gather information about genetic variants of uncertain significance, such as the one identified in your test, will continue.
• If new information becomes available about your variant, it will be sent to the healthcare provider who ordered your test.

Your Cancer Risks

• Your cancer risks should be estimated based on your personal and family history of cancer.
• Your healthcare provider can assist you in understanding these risks.
• The possibility remains that your cancer risks could be increased due to:
  • Ultimately finding that your variant causes hereditary melanoma syndrome.
  • Other non-hereditary factors (for example: environment).
  • Another hereditary cancer syndrome.
  • A mutation in p16 that current technology cannot detect.

Managing Your Risks

• It is best to manage your cancer risks based on your personal and family history.
• You and your healthcare provider can develop the most appropriate plan for your medical management.
• Your healthcare provider can help you determine whether any further genetic testing should be offered to you or to a family member.

It’s a Family Affair

• Based on your test result it is not clear if hereditary melanoma syndrome caused by the p16 gene runs in your family.
• Some of your relatives may be offered research testing at no charge to gather more information about your variant. Talk to your healthcare provider about this option.

If you need a copy of your genetic test result, please contact the healthcare provider who ordered your test.

• Obtain a copy of your test result.
• Schedule consultations with appropriate healthcare providers.
• Create a plan for medical management.
