Early diagnosis of ATTR amyloidosis through targeted follow-up of identified carriers of TTR gene mutations.

Abstract

Diagnosis in the early stages of hereditary transthyretin (ATTR) amyloidosis is imperative to support timely treatment to prevent or delay disease progression. Genetic testing in the setting of genetic counselling enables identification of carriers of a TTR gene mutation who are therefore at risk of developing TTR-associated disease. Knowledge of different genotypes and how they manifest in symptomatic disease should facilitate development of a structured and targeted approach to enable diagnosis of symptomatic disease in ATTR amyloidosis mutation carriers on the first manifestation of the earliest detectable sign or symptom. A group of experts from across Europe, Israel and Japan met to reach a consensus on such an approach. The proposed approach involves establishing a baseline for key clinical parameters, determination of the timing and frequency of follow-up in TTR mutation carriers based on a predicted age of disease onset, and recognition of the likely initial clinical signs and symptoms aligned with the phenotype of the specific TTR gene mutation and family history. Minimum criteria for diagnosis of symptomatic disease have been agreed, which it is hoped will ensure diagnosis of ATTR amyloidosis at the earliest possible stage in people with a known TTR mutation.
