Six inflammatory proteins (CCL19, CDCP1, uPA, TSLP, IL-22RA1, and SCF) associated with two or more types of hearing loss were further validated in the validation set “hearing loss, difficulty in hearing” (ebi-a-GCST90018857) (Supplementary Table S6A), and the results are presented in Figure 3. Here, CDCP1 is linked to hearing loss disorder.
