A recent study corroborates these findings, noting that transthyretin amyloid cardiomyopathy (ATTR-CM), a form of cardiac amyloidosis, is a progressive and life-threatening condition, leading to restrictive cardiomyopathy and heart failure as a result of the deposition of misfolded transthyretin protein in the myocardium [20]. The gene discussed is TTR; the disease is cardiac amyloidosis.
