Additionally, a positive correlation between RAB42 expression and TMB was exhibited in breast invasive carcinoma (BRCA), COAD, LGG, LUAD, OV and SARC, while a negative correlation was found in HNSC, SKCM, thyroid carcinoma (THCA) and thymoma (THYM) (Figure S6B). This evidence concerns the gene RAB42 and thyroid gland carcinoma.
