Genes affected

ORM2 (HGNC:8499): (orosomucoid 2) This gene encodes a key acute phase plasma protein. Because of its increase due to acute inflammation, this protein is classified as an acute-phase reactant. The specific function of this protein has not yet been determined; however, it may be involved in aspects of immunosuppression. [provided by RefSeq, Jul 2008]

ORM2 links:

AKNA (HGNC:24108): (AT-hook transcription factor) Predicted to enable DNA binding activity. Involved in positive regulation of transcription by RNA polymerase II. Located in centrosome; cytosol; and nuclear lumen. [provided by Alliance of Genome Resources, Apr 2022]
