Low affinity immunoglobulin γ Fc region receptor III‐A was increased in abundance in both sporadic and C9orf72 FTD, in addition to CD163, α‐1‐antichymotrypsin (SERPINA3), and latent‐transforming growth factor β‐binding protein 2 in sporadic FTD only. The gene discussed is SERPINA3; the disease is frontotemporal dementia.
