No-charge genetic testing for acute hepatic porphyria

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

On average, it takes up to 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 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?

Porphyria is a family of rare, genetic diseases characterized by potentially life-threatening attacks and, for some patients, chronic debilitating symptoms that negatively impact daily functioning and quality of life. Porphyria includes eight subtypes, and each has unique manifestations, making an accurate diagnosis even more challenging.

Four of these subtypes, a family of diseases referred to as acute hepatic porphyria (AHP), result from a genetic defect leading to deficiency in one of the enzymes of the heme biosynthesis pathway in the liver: acute intermittent porphyria (AIP), variegate porphyria (VP), hereditary coproporphyria (HCP), and ALAD-deficiency porphyria (ADP).

Program eligibility
  • Patient is at least 16 years old, with elevated (greater than the upper limit of normal) urinary porphobilinogen (PBG) or aminolevulinic acid (ALA) levels


OR
  • Patient is at least 16 years old with unexplained recurrent (more than one), prolonged (>24 hours) episodes of severe, diffuse (poorly localized) abdominal pain, AND
  • At least 2 of the following:
    • Red to brownish urine
    • Known or suspected family history of acute hepatic porphyria
    • Blistering skin lesions on sun-exposed areas
    • Peripheral nervous system manifestations occurring around the time of abdominal pain (i.e., motor neuropathy [paresis], sensory neuropathy [numbness, tingling, limb pain])
    • Central nervous system manifestations occurring around the time of abdominal pain (i.e., confusion, anxiety, seizures, hallucinations)
    • 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 misdiagnosis
  • Help patients consider clinical trials

Genetic testing with Invitae

The Alnylam Act® program offers testing for the 4 genes associated with the acute hepatic porphyrias:

  • ALAD
  • CPOX
  • HMBS
  • PPOX

Family testing

If the test comes back positive, Invitae offers genetic testing for all blood relatives of the original patient.

  • If a family member meets eligibility criteria, consider ordering the test 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 does offer family variant testing (FVT) at no charge to all of the original patient's blood relatives. Visit www.invitae.com/family-testing for details. Please note that FVT orders must be placed within 90 days of the original test report date to qualify.
