• Estimated glomerular filtration rate ≤30 mL/min/1.73 m2
• Inability to safely undergo CMRI (For participants with symptomatic V122I hATTR-CA, we will enroll probands with HF from Aim 1 or patients with symptomatic V122I hATTR-CA from the three study sites.)
• Men and women ages 30-80 who have symptomatic V122I hATTR-CA as determined by a history of HF (this will be assessed by study personnel) and defined as: a) History of hospitalization within the previous 12 months for management of HF; b) An elevated B-type natriuretic peptide level ≥100 pg/mL or NT-proBNP ≥360 pg/mL within the previous 12 months; or c) A clinical diagnosis of HF from a treating clinician.
• Have an established diagnosis of hATTR-CA based on either a) Biopsy confirmed by Congo red (or equivalent) staining with tissue typing with immunohistochemistry or mass spectrometric analysis or immunoelectron microscopy, OR b) positive technetium-99m (99mTc)-pyrophosphate or -bisphosphonate scan, combined with accepted laboratory criteria without abnormal M-protein.
• TTR gene sequencing confirming the V122I variant
• Signed informed consent
• Other known causes of cardiomyopathy
• History of light-chain cardiac amyloidosis
• Cardiac transplantation
• Liver transplantation
• Previous Treatment with a TTR stabilizer (tafamidis, acoramidis) or TTR silencer (inotersen, patisiran, eplontersen)
• Estimated glomerular filtration rate ≤30 mL/min/1.73 m2

• Established diagnosis of definite or probable AD or have a diagnosis of a related neurodegenerative disorder such as Frontotemporal Dementia (FTD) or Lewy Body Dementia (LBD) (will also recruit sporadic FTD and LBD) cases.
• a living sibling with probable or possible AD;
• a third living relative affected with AD (onset age 50 or older) or unaffected (60 or older);
• participants in the proband's generation with an identified companion serving as an informant;
• participants who have capacity to consent or participants lacking capacity to consent with a surrogate/proxy in place to provide consent.
• failure to identify an appropriate informant;
• uncertainty of the clinical diagnosis of Alzheimer's disease or other related disorder;
• discovery of additional diagnosis that could account for the clinical manifestations;
• unwillingness to participate;
• failure to identify a living sibling with AD or other related disorder (except in the cases of sporadic FTD and sporadic LBD);
• participants lacking the capacity to consent who do not have a surrogate or proxy or next of kin to provide consent.
