Genotype-Phenotype Correlations in ATTR Amyloidosis

Hereditary transthyretin-related amyloidosis (hATTR) is the most common form of familial amyloidosis. It is an autosomal dominant disease caused by a pathogenic variant in the TTR gene. More than 140 TTR gene variants have been associated with hATTR, with the Val30Met variant representing the most common worldwide. The clinical phenotype varies according to the gene variant and includes predominantly cardiac, predominantly neurologic, and mixed phenotypes. The present review aims to describe the genotype-phenotype correlations in hATTR. Understanding these correlations is crucial to facilitate the early identification of the disease, predict adverse outcomes, and guide management with approved disease-modifying therapies.
