When comparing kidney cancers, KIRC illustrated higher FOLH1 expression relative to normal kidney (log2FC = 2.03, p = 2.69 × 10−56), liver (log2FC = 0.33, p = 1.73 × 10−4), salivary gland (log2FC = 0.24, p = 0.019), small intestine (log2FC = 3.99, p < 1 × 10−300), and spleen (log2FC = 3.13, p < 1 × 10−300). Here, FOLH1 is linked to kidney cancer.
