Genes affected

CD74 (HGNC:1697): (CD74 molecule) The protein encoded by this gene associates with class II major histocompatibility complex (MHC) and is an important chaperone that regulates antigen presentation for immune response. It also serves as cell surface receptor for the cytokine macrophage migration inhibitory factor (MIF) which, when bound to the encoded protein, initiates survival pathways and cell proliferation. This protein also interacts with amyloid precursor protein (APP) and suppresses the production of amyloid beta (Abeta). Multiple alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Aug 2011]

Collection Method: clinical testing

The c.674C>T (p.P225L) alteration is located in exon 7 (coding exon 7) of the CD74 gene. This alteration results from a C to T substitution at nucleotide position 674, causing the proline (P) at amino acid position 225 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
