Fig. 4: NK cell eQTL determine protein expression on NK cells in patients with metastatic melanoma.

Genotype-phenotype correlations are calculated by linear regression. P values are calculated with likelihood ratio tests. Expression of CD57 (orange, nā=ā78) and CD226/DNAM1 (blue, nā=ā24) protein on NK cells is determined by the respective RNA eSNPs in patients with metastatic melanoma. KIR2D antigen expression on NK cells in patients with metastatic melanoma (nā=ā78) is modified by KIR2DS4del copy number (pink). Box and whisker plots; boxes depict the upper and lower quartiles of the data, and whiskers depict the range of the data excluding outliers (outliers are defined as data-pointsā>ā1.5āĆāthe inter-quartile range from the upper or lower quartiles). Genotype to phenotype correlations were calculated with linear regression. P values are two-sided.
