Genes affected

MIF (HGNC:7097): (macrophage migration inhibitory factor) This gene encodes a lymphokine involved in cell-mediated immunity, immunoregulation, and inflammation. It plays a role in the regulation of macrophage function in host defense through the suppression of anti-inflammatory effects of glucocorticoids. This lymphokine and the JAB1 protein form a complex in the cytosol near the peripheral plasma membrane, which may indicate an additional role in integrin signaling pathways.

Ambry Genetics

Oct 05, 2023

The c.220C>G (p.R74G) alteration is located in exon 2 (coding exon 2) of the MIF gene. This alteration results from a C to G substitution at nucleotide position 220, causing the arginine (R) at amino acid position 74 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
