In this model, both AT1-AAs (β = 0.057, p = 0.050) and age (β = 0.050, p = 0.010) were significantly associated with PD diagnosis, whereas other variables, including MasR-AAs and ACE2-AAs, did not reach statistical significance (Supplementary Table S13). The gene discussed is AGTR1; the disease is Parkinson disease.
