DBH and cataract: DBH gene is significantly enriched in response to light stimulation (SUID = 15,809, adjusted p‐Value = 5.56E‐03), radiation (SUID = 15,601, adjusted p‐Value = 5.56E‐03), abiotic stimulus (SUID = 15,639, adjusted p‐Value = 5.56E‐03) and other biological processes, which is consistent with the previously reported age‐related cataract susceptibility factors in the population in eastern China.
