No-charge genetic testing for acute hepatic porphyria

Invitae and Alnylam have partnered to offer genetic testing at no charge for individuals who may carry a gene mutation known to be associated with acute hepatic porphyria (AHPs).

On average, it takes 15 years from symptom onset for a patient to receive a correct diagnosis of AHP.1 The Alnylam Act® program was developed to reduce barriers to genetic testing and counseling in order to help people make more informed decisions about their health.

While Alnylam provides financial support for this program, tests and services are performed by independent third parties. Healthcare professionals must confirm that patients meet certain criteria to use the program. Alnylam receives de-identified patient data from this program, but at no time does Alnylam receive patient identifiable information. Alnylam receives contact information for health care providers who use this program. Genetic testing is available in the US and Canada. Genetic counseling is only available in the US. Healthcare professionals who use this program have no obligation to recommend, purchase, order, prescribe, promote, administer, use or support any Alnylam product.

What is porphyria?

Porphyrias are a group of rarely diagnosed disorders that are classified based on the predominant site of enzyme defect and where heme precursors accumulate in the heme biosynthesis pathway.

The acute hepatic porphyrias—including acute intermittent porphyria (AIP), variegate porphyria (VP), hereditary coproporphyria (HCP), and ALAD-deficient porphyria (ADP)—are characterized by acute, potentially life-threatening attacks and chronic, debilitating symptoms that negatively impact patients’ quality of life.

    • Autonomic nervous system manifestations occurring around the time of abdominal pain (i.e., hyponatremia [Na < LLN], tachycardia, hypertension, nausea and vomiting, constipation)

Benefits of testing

The benefits of genetic testing include the ability to:

  • Identify risk of disease for patients and their family members
  • Shorten the time to diagnosis and help prevent misdiagnoses
  • Help determine if patients are eligible to participate in clinical trials
  • Provide information about support services such as patient advocacy organizations

Family testing

If the test comes back positive, Invitae encourages genetic testing for first-degree relatives of the original patient.

  • If a family member meets eligibility criteria, order testing through the Alnylam Act program.

  • Family members who don't meet eligibility criteria do not currently qualify for testing under the Alnylam Act program. However, Invitae can offer family variant testing at no charge. Learn more >
