Of the 21 genes tested, four showed differential expression, with Acyloxyacyl Hydrolase (AOAH), Engulfment and Cell Motility 1 (ELMO1), Hyaluronan synthase 2 (HAS2) and Interleukin 6 (IL6) all showing higher expression in the renal samples from amyloidosis positive individuals (Figure 3D). This evidence concerns the gene HAS2 and amyloidosis.
