SDC1 and amyloidosis: We retrospectively analyzed 63 consecutive patients with AL amyloidosis who were referred to our Amyloidosis Center from March 2014 to May 2015 and were thoroughly assessed using IHC for the amyloid deposits in organs, serum as well as urine immunofixation (IF), serum FLC test, BM cytology, BM MFC, BM IHC, and interphase fluorescence in situ hybridization (iFISH) on sorted CD138+ BM PCs.
