ESRG and cancer: Five genes (UHMK1, RALYL, MGST3, USP9X, ESRG) are directly related with the drug resistance phenotype, while the remaining four genes (SPINK13, LINC00664, MRPL38, EMILIN3) do not have a known direct relationship with drug resistance in cancer, but they belong to families of genes that are known to be involved in drug resistance.
