Our study was inconsistent with the results of a study on ADRB1 (1165G > C) polymorphism and ischemic stroke in North India, which recruited 224 patients and 224 age- and sex-matched controls and discovered no association between ADRB1 (GC + GG vs. CC) and overall ischemic stroke [44]. The gene discussed is ADRB1; the disease is ischemic stroke.
