No-charge genetic testing for primary hyperoxaluria type 1

Alnylam has partnered with Invitae to offer genetic testing at no charge for individuals who may carry gene mutations known to be associated with primary hyperoxaluria type 1 (PH1).

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 primary hyperoxaluria type 1?

The primary hyperoxalurias are inherited disorders of glyoxylate metabolism in which hepatic enzyme deficiencies result in excessive endogenous production of oxalate.  The excess oxalate cannot be degraded and is excreted in large amounts by the kidneys, resulting in accumulation of oxalate and progressive kidney disease.1

Most patients with primary hyperoxaluria present with signs or symptoms related to kidney stones, which are observed in 65% of patients before 10 years of age and in up to 80% before 20 years of age.2
