Diagnosis of hereditary transthyretin-mediated polyneuropathy~5. BMI \> 16 kg/m2~Exclusion Criteria for hATTR Patients (Cohort D)~1. Clinically-significant (CS) abnormalities in medical history, screening laboratory results, physical or physical examination that would render a subject unsuitable for inclusion, including but not limited to abnormal safety labs~2.
