Fabry disease (FD) is the second most common lysosomal storage disorder, carrying a large morbidity and mortality. It has been recently reported that lysosomal storage disorders could cause inflammation and, subsequently, AA amyloidosis (AAA). Our aim was to describe AAA cases occurring in the course of FD. We described two patients displaying both AAA and FD and an additional case from the literature. Three female patients originating from Europe (n = 2) and Algeria (n = 1) harboured heterozygous GLA mutations. The median age at AAA diagnosis was 61 years old. The diagnosis of Fabry was made before the diagnosis of AAA (n = 1) or concomitantly (n = 2). At AAA diagnosis, two patients displayed a nephrotic syndrome; all had inflammation. Fabry disease can be associated with AAA, suggesting that an inflammatory component could exist in this genetic disease. © 2020 John Wiley & Sons Ltd.
