The Kyowa Kirin Sponsored Hypophosphatemia Program

Sponsored, no-charge genetic testing
US and Canada

What is the Kyowa Kirin Sponsored Hypophosphatemia Program?

Kyowa Kirin Inc. and Invitae have partnered to offer sponsored, no-charge genetic testing and counseling to patients being evaluated for a possible diagnosis of X-linked hypophosphatemia (XLH) or tumor-induced osteomalacia (TIO), are aged 6 months or older (for XLH) and 2 years or older (for TIO), reside in the United States or Canada, and meet certain other eligibility criteria.

An accurate diagnosis may impact the clinical management of the condition, including customizing care to a patient's specific needs. The Kyowa Kirin Sponsored Hypophosphatemia Panel (13 genes) is designed to provide optimal diagnostic yield for patients with genetic forms of hypophosphatemia, based on the current scientific understanding. This panel also provides reasonable exclusionary yield for patients who are suspected of having TIO, in whom we would expect normal genetic test results.

The Kyowa Kirin Sponsored Hypophosphatemia Program is intended to improve patient safety and quality of care by shortening the time to an accurate diagnosis, facilitate prompt confirmatory testing, and help patients with XLH or TIO meet payor coverage requirements. Use of or participation in the Kyowa Kirin Sponsored Hypophosphatemia Program does not create any obligation to use, prescribe, or recommend any Kyowa Kirin products or services. No patient or health care provider may seek reimbursement for testing or counseling services provided under the Kyowa Kirin Sponsored Hypophosphatemia Program from any third party, including but not limited to, any government health care programs.

    • About XLH

      XLH, the most common form of genetic hypophosphatemia, is caused by pathogenic variants in the PHEX gene.1 XLH is an X-linked condition, meaning that the genetic variant (located on the X chromosome) only needs to exist in one copy of a patient’s genes to cause the condition. Women with XLH have a 50% chance of passing the condition to their children, regardless of gender, while men with XLH will pass it on to all their daughters and none of their sons.2

    • About TIO

      TIO is a paraneoplastic condition of abnormal phosphorus and vitamin D metabolism caused by small, benign endocrine tumors that secrete the phosphaturic hormone, fibroblast growth factor 23 (FGF23), leading to impaired bone metabolism.3
