Similarly, we were also able to evaluate mRNA expression of the genes encoding these three protein biomarkers via BioGPS (biogps.org) and found the expression of GPR64 and AMER2 in EWS patient tumor samples to be consistent regardless of stage of disease, whereas UGT3A2 expression was not available in this dataset (Supplementary Figure S4). Here, ADGRG2 is linked to neoplasm.
