1) With a "Genotype" run one can identify gene(s) showing altered expression in samples harbouring a mutated input gene. This option is useful in case one searches new drug targets in a cohort of patients with a given mutation.
2) With a "Target" run one can identify mutations resulting in expression change in the input gene. This option is useful in case one has a drug target gene, and patient cohorts with enriched expression is the question.
These analyses are available for 18 tumor types.
