Genes affected

CCR2 (HGNC:1603): (C-C motif chemokine receptor 2) The protein encoded by this gene is a receptor for monocyte chemoattractant protein-1, a chemokine which specifically mediates monocyte chemotaxis. Monocyte chemoattractant protein-1 is involved in monocyte infiltration in inflammatory diseases such as rheumatoid arthritis as well as in the inflammatory response against tumors. The encoded protein mediates agonist-dependent calcium mobilization and inhibition of adenylyl cyclase. This protein can also be a coreceptor with CD4 for HIV-1 infection. This gene is located in the chemokine receptor gene cluster region of chromosome 3. [provided by RefSeq, Aug 2017]

The c.75T>A (p.D25E) alteration is located in exon 2 (coding exon 1) of the CCR2 gene. This alteration results from a T to A substitution at nucleotide position 75, causing the aspartic acid (D) at amino acid position 25 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
