Patients with this disorder typically present with proteinuria. Isolated cases of AFib amyloidosis, carrying the FGA p.Glu545Val variant, were identified in the district of Braga, in northwest Portugal. This observation led us to hypothesize that this disorder might be an unrecognized cause of kidney disease in that region and prompted us to carry out targeted genetic testing for the p.Glu545Val variant in the local hemodialysis population and family members of identified cases.engAgedAmyloidosisFemaleFibrinogenGenetic TestingHumansKidney DiseasesMaleMiddle AgedRetrospective StudiesMutationDoenças Genéticasjournal article10.1053/j.ajkd.2017.01.048
