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 GeneticsNov 18, 2022The c.79G>C (p.V27L) alteration is located in exon 1 (coding exon 1) of the ORM2 gene. This alteration results from a G to C substitution at nucleotide position 79, causing the valine (V) at amino acid position 27 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
