Alnylam Act®: Third-Party Genetic Testing and Counseling Programs Offered at No Charge

Alnylam is sponsoring no-charge third-party genetic testing and counseling for individuals who may carry a gene mutation known to be associated with acute hepatic porphyrias (AHPs). The Alnylam Act® program was created to reduce barriers to genetic testing and counseling to help people make more informed decisions about their health.

 

The genetic testing service is available in the United States and Canada and the genetic counseling service is available in the United States. Learn more about what genetic testing and counseling are and how the process works here or by downloading the brochures below. Healthcare professionals who use this program have no obligation to recommend, purchase, order, prescribe, promote, administer, use or support any Alnylam product.

About Acute Hepatic Porphyrias

Acute hepatic porphyrias (AHPs) are comprised of four subtypes, each resulting 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 ALA dehydratase-deficiency porphyria (ADP).

AHPs are a family of rare, genetic diseases characterized by potentially life-threatening attacks and, for many patients, chronic debilitating symptoms that negatively impact daily functioning and quality of life.

Common symptoms include severe, diffuse abdominal pain, weakness, nausea, and fatigue.

HCP and VP are classified as acute but can also have symptoms that affect the skin—specifically blistering skin lesions on sun-exposed areas. Skin symptoms can be present with or without attacks.

Privacy

While Alnylam provides financial support for this program, all tests and services are performed by independent third parties. Healthcare professionals must confirm that the 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 healthcare professionals who use this program.

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