To more directly assess the possible relationship between Msi2 variant 2 expression and cancer, we assessed the relative expression levels of both canonical Msi2 and Msi2 variant 2 transcript expression in 12 different cancers, using publically available RNA-seq data from the Cancer Genome Atlas (TCGA) via the Cancer RNA-seq Nexus web portal57. This evidence concerns the gene MSI2 and cancer.
