Several other proteins also showed a sub‐threshold change in abundance, including Apolipoprotein B (APOB) and chitinase‐like protein 2 (CHI3L2) which have previously been linked to ALS in other studies (Thompson et al., 2019; Thompson, Talbot, et al., 2022). The gene discussed is APOB; the disease is amyotrophic lateral sclerosis.
