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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 09, 2024The c.217A>G (p.K73E) alteration is located in exon 2 (coding exon 2) of the ORM2 gene. This alteration results from a A to G substitution at nucleotide position 217, causing the lysine (K) at amino acid position 73 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
