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.

Collection Method: clinical testing

The c.195C>G (p.I65M) 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 195, causing the isoleucine (I) at amino acid position 65 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
