The Norfolk Quality of Life-Diabetic Neuropathy (QOL-DN) questionnaire is an instrument to assess QOL in diabetic polyneuropathy. The objective of this observational, cross-sectional study in 61 patients with V30M transthyretin familial amyloid polyneuropathy (TTR-FAP) and 16 healthy volunteers was to validate the Norfolk QOL-DN for assessment of QOL in TTR-FAP. Comparisons were conducted to identify the best items to discriminate disease stages and assess which individual Norfolk domains (symptoms, large fiber, small fiber, autonomic, and activities of daily living) would be most affected by disease stage. Analysis of individual items revealed a significant pattern of discrimination among disease stages (p
