hATTR Polyneuropathy in Russia

A multicenter observational retrosPective Registry of patIents with transthyretin aMyloid polynEuropathy (hATTR-PN) and chRonic idiopathic axonal polyneuropathy (CIAP) in the population of the Russian Federation (PRIMER) There are no comprehensive epidemiological data on patients with hereditary ATTR-PN (hATTR-PN) and CIAP in the Russian Federation. Therefore, there is a need to conduct a large-scale observational study in the Russian population to obtain information on clinical, electrophysiological and demographic characteristics of patients with hATTR-PN and CIAP. Obtaining the study data will help to identify the patients with axonal polyneuropathy, who deserve TTR gene sequencing, and therefore to allow early treatment and potentially modify disease progression in patients.
