Genes affected

TUSC2 (HGNC:17034): (tumor suppressor 2, mitochondrial calcium regulator) Predicted to be involved in inflammatory response and regulation of mitochondrial membrane potential. Predicted to act upstream of or within several processes, including natural killer cell differentiation; neutrophil-mediated killing of gram-negative bacterium; and regulation of cytokine production. Predicted to be active in mitochondrion. [provided by Alliance of Genome Resources, Apr 2022]
