L2HGDH and neoplasm: Furthermore, the copy number of HIF1A correlates much stronger with L2HGDH expression (Rho = 0.55) than its own gene expression (Rho = 0.27) revealing that there is a high degree of preserved-allele compensation of HIF1A in 14q deleted RCC (compared to L2HGDH as well as other potential 14q tumor-suppressors identified in this article).
