MICA and cancer: Finally, in the analyses of cancer-associated MICA SNPs, s-MICA levels were greater among participants with the MICA-129 Val / Val genotype (S3 Table), but this association was only statistically significant for pancreatic cancer cases with the MICA-129 Val / Val genotype who had 3.06 times great mean s-MICA levels [95% CI: 1.62–5.77)] compared to cases with MICA-129 Met/Val genotype.
