FCGR1A genotypes containing the rs587598788-c.845-17delTCTTTG (rs587598788Del) allele are significantly associated with low CD64 expressions. (A) Monocytes from rs587598788-c.845-23 (rs587598788In) homozygous donors (In/In) expressed significantly higher levels of CD64 than those from the combined rs587598788 heterozygous (In/Del) and rs587598788Del homozygous (Del/Del) donors (Mann-Whitney test P = 0.0136). (B) CD64 expression data from a replication cohort confirmed that rs587598788-In/In homozygous donors expressed significantly higher levels of CD64 than those from the combined rs587598788-In/Del heterozygous and Del/Del homozygous donors. (C) CD64 expression levels on monocytes were not significantly different between the SNV rs1050204-G/G homozygous donors (G/G, N = 207) and the combined rs1050204-G/A heterozygous and rs1050204-A/A homozygous donors (Mann-Whitney test P = 0.488).
