Genetic testing improves identification of transthyretin amyloid (ATTR) subtype in cardiac amyloidosis

Abstract excerpt

Amyloidosis is a group of conditions characterized by the accumulation of amyloid deposits in various tissues. Among these disorders, ATTR amyloidosis occurs either with or without a TTR pathogenic variant. Treatment for amyloidosis depends on the subtype, which is often identified through a tissue biopsy followed by liquid chromatography tandem mass spectrometry (LC-MS/MS). Genetic testing may be done to confirm...
