In the seven genes previously associated with AD in AAs, nominally significant associations were observed for a rare LOF variant in MS4A6A observed only in controls (rs140130948, p = 0.013) and an 11 bp ABCA7 deletion (rs567222111, OR = 3.57, p = 0.038) which had an estimated allele frequency (AF) of 1.1% in cases and 0.32% in controls (Table 2). The gene discussed is ABCA7; the disease is Alzheimer disease.
