NCT05974644

Brief Summary

The study design is a prospective registry including asymptomatic and symptomatic patients who carry a pathogenic TTR mutation. The study will enroll patients who meet the inclusion criteria and none of the exclusion criteria until 1000 patients are enrolled, at which point in time the study investigators will evaluate whether further patient accrual is meaningful.

Outcome Measures

Primary Outcomes (2)

  • The predictors and incidence of amyloidosis

    For those enrolled as asymptomatic carriers, it will be assessed if they develop cardiac or extra cardiac amyloidosis

    15 years

  • Mortality and/or need for heart transplant

    For those with cardiac hereditary transthyretin amyloidosis (hATTR), it will be assessed how many participants die due to disease or require a heart transplant

    10 years

Study Arms (2)

Asymptomatic carriers

Other: Registry

Patients with cardiac hereditary transthyretin amyloidosis (hATTR)

Other: Registry

Interventions

The purpose of this registry is to collect and store health information from people who are carriers of the gene known to cause hereditary amyloidosis and those with a confirmed diagnosis of the disease.

Study Population

Any carriers of a pathogenic TTR mutation known to cause hATTR amyloidosis will be recruited to the registry.

You may qualify if:

  • Over the age of 18 years
  • Carrier of a pathogenic hATTR mutation confirmed on whole blood gene testing or mass spectrometry
  • Willing to return for required follow-up visits

You may not qualify if:

  • Patient having undergone heart transplantation or implantation of mechanical circulatory support
  • Patients unable to provide informed consent
