The general enhanced expression of α1-antichymotrypsin (ACT), clusterin (CLU), α1-antitrypsin (AAT), haptoglobin β-chain (HAP), and leucine rich glycoprotein (LRG) in the sera of patients with epithelial ovarian carcinoma (EOCa) was recently reported. Here, LRG1 is linked to early-onset cerebellar ataxia with retained tendon reflexes.
