Deep Phenotyping of F64L Mutation in a Multicentric Cohort of Patisiran-Treated Hereditary Transthyretin Amyloidosis Patients (Patisiranitaly).
Article in European journal of neurology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe F64L variant is among the most frequent TTR mutations in Italy, typically associated with a predominantly neurologic phenotype and limited cardiac involvement.
methodsData from 181 ATTRv patients in the multicenter Patisiranitaly database treated with Patisiran since 2020 were analyzed. Neurologic impairment scores, Norfolk QoL-DN, and cardiac parameters were compared between F64L (n = 56), V30M (n = 37), and non-F64L (n = 125) patients at baseline and during follow-up. Cluster analysis was applied to identify patient subgroups based on these variables.
resultsF64L represented 30.9% of the cohort. Compared to non-F64L patients, F64L patients had a higher prevalence of neurologic onset and neurologic phenotype, a thinner interventricular septum, and lower NT-proBNP levels. Cluster analysis segregated patients into two distinct groups, predominantly reflecting F64L vs. non-F64L status and corresponding neurologic severity. F64L patients showed milder cardiac involvement compared to V30M patients. Longitudinal repeated-measures ANOVA showed stable clinical and instrumental measures.
conclusionsF64L is characterized by predominant neurologic involvement and milder cardiac involvement in this Patisiran-treated cohort. Mutation-specific diagnostic and follow-up strategies are essential to capture its natural history and treatment response.
