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]

The c.571G>A (p.E191K) alteration is located in exon 6 (coding exon 6) of the ORM2 gene. This alteration results from a G to A substitution at nucleotide position 571, causing the glutamic acid (E) at amino acid position 191 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
