CD93 and neoplasm: When comparing the genotype frequencies of SNP rs2749817 to tissue levels of total CD93, the tumour tissue levels were significantly higher (20 %) among patients with T/T genotype (mean, 8.3; SD, 3.10 ng/mg) compared with C/C and C/T genotypes (mean, 6.9; SD, 3.36 ng/mg) (P = 0.037).
