Hereditary amyloidosis is a life-threatening disorder that can lead to peripheral neuropathy and heart failure. Early diagnosis and treatment of hereditary amyloidosis can provide a normal quality of life and lifespan for your patients. This new in-house test will be performed at our main laboratory for prompt results and is complementary to HNL Genomics Cardiology offerings.

The TTR test is a Sanger sequencing test that detects pathogenic variants in the TTR gene which cause hereditary transthyretin amyloidosis. These pathogenic variants change the structure of the TTR protein leading to the progressive buildup of amyloid protein in the body's organs, including the heart, kidneys, eyes, and gastrointestinal tract.


Use this test to pursue pharmacotherapies designed specifically for individuals with pathogenic TTR variants. Results provide valuable family medical history information that allow family members to pursue testing. If positive for a pathogenic variant, patients and family members may obtain an early diagnosis or be monitored for signs and symptoms before they occur.

Providers suspecting hereditary transthyretin amyloidosis can order this test easily in EPIC using code C7001. Our genetic testing experts are available to assist with any questions. Compared to three weeks with competitors, the turnaround time for our TTR test is just 7-14 days. Results are available in EPIC.

Test Summary

  • Transthyretin amyloidosis
  • Detects variants in TTR gene
  • EPIC Code C7001
  • Turnaround Time: 7-14 days

The Effect of Genetics on Individual Heart Health: Early Identification of FH Variations to Optimize Treatment

Test must be ordered by a Physician.

Familial hypercholesterolemia (FH) is a genetic disorder that is characterized by abnormally high blood levels of low-density lipoprotein (LDL) cholesterol, sometimes referred to as "bad cholesterol". This condition affects an estimated 1 in 250 people, and increases the likelihood of developing cardiovascular disease. In fact, FH is estimated to be the cause of 2-3% of heart attacks in individuals younger than age 60.
