AR and Alzheimer disease: Comparing inheritance patterns showed that 111/153 (72.5%) hc-BAE genes and 18/31 (58.1%) hc-RAE genes had AR inheritance, 27/153 (17.6%) hc-BAE genes and 9/31 (29%) hc-RAE genes had AD inheritance, and 15/153 (9.8%) hc-BAE and 4/31 (13%) hc-RAE genes had both AR and AD inheritance, yielding no significant difference in inheritance pattern (AD versus AR) for BAE versus RAE (p = 0.257).
