The purpose of this project is to study DNA and its connection to your health. DNA is in your blood, your saliva, and other tissues in your body. DNA is the unique instructions you are born with that tells your body how to work. By looking at DNA, you can learn information about your health, certain traits, and even your ancestral roots. DNA is also called your genetic information. DNA is mostly the same from person to person. But everyone's DNA is slightly different. We are still learning how DNA impacts health. This study will look at the DNA of many different people from many different backgrounds and compare it to information in their health records. The goal is to understand how learning about DNA can help improve health care for individuals, families, and the community.

Participants will provide a sample for DNA sequencing. Sequencing is the process of reading the letters of your DNA. This study may sequence your whole genome. Over time, you may be asked to provide additional samples for research purposes. The research team will collect health information about you from your medical record and may ask you questions about your health using surveys or other data collection method.

Amyloidosis (ATTR) Cardiomyopathy (CM) is a progressive, fatal disease in which amyloid deposits build up slowly, over the course of many years to cause organ damage. This study will continue to evaluate the safety and tolerability of a new drug called acoramidis given to adult patients with symptomatic transthyretin amyloid cardiomyopathy. All participants will be given the study medication, which is taken by mouth twice a day.

This study is enrolling subjects who participated in the AG10 301 study, and are eligible to enroll in this study within 30 days of completing the 30 month visit for the AG10 301 study. This study is expected to last approximately 5 years and will have in person visits at day 1, month 1 and then every 6 months along with phone visits quarterly when an in person visit is not required.

The purpose of this study is to evaluate the safety and effectiveness of ION-682884 and determine if it can help people with transthyretin-mediated amyloid cardiomyopathy (ATTR-CM) which is a disease caused by change in a protein called transthyretin (TTR). ION-682884 is an investigational drug. "Investigational" means that ION-682884 is not yet approved for use in any settings outside of clinical research studies like this one and is considered experimental. ION-682884 has been shown to reduce the level of TTR in the blood of animals and healthy volunteers tested to date. Reducing the amount of TTR in your blood may reduce the amount of amyloid deposits in your body and may keep your cardiomyopathy from getting worse over time. However, it is not known if ION-682884 will help your cardiomyopathy.

If you meet the requirements and agree to participate in this study, you will receive subcutaneous (under the skin) injections of either ION-682884 or placebo once every 4 weeks from week 1 through week 137.
Your participation in this study will last approximately 36 months and will consist of clinic visits and follow up visits at home.

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics (the levels of drug in the blood) and pharmacodynamics (the effect of the drug on your body) of the study drug, MYK-491, when administered orally twice a day for about one to two weeks.The study will recruit patients with an enlarged heart and weakened heart muscle not caused by heart damage from a heart attack or heart valve problem. Eligible patients must also have a specific genetic mutation called MHY7. All subjects that qualify will receive MYK-491 (no placebo, or inactive pill will be dispensed during the study). The study medication is designed to improve cardiac contractility or the ability of the heart to squeeze.

This study has two treatment periods during which multiple doses of MYK-491 (the study drug) will be administered. Once Treatment Period 1 is completed, participants will return to the clinical site for study assessments and to obtain a dose for Treatment Period 2. The investigator will review the results of the study assessments and participants will learn if they will receive a lower or higher dose of MYK-491 for Treatment Period 2 than they received in Treatment Period 1. The expected study duration ranges from about 4 weeks to 11 weeks, including about 1-8 weeks for screening, 9 to 15 days for IMP dosing and an approximately 1 week (7±1 days) follow-up visit.
