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.197T>A (p.F66Y) alteration is located in exon 2 (coding exon 2) of the ORM2 gene. This alteration results from a T to A substitution at nucleotide position 197, causing the phenylalanine (F) at amino acid position 66 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
