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.493T>G (p.C165G) alteration is located in exon 5 (coding exon 5) of the ORM2 gene. This alteration results from a T to G substitution at nucleotide position 493, causing the cysteine (C) at amino acid position 165 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
