Genes affected

CCRL2 (HGNC:1612): (C-C motif chemokine receptor like 2) This gene encodes a chemokine receptor like protein, which is predicted to be a seven transmembrane protein and most closely related to CCR1. Chemokines and their receptors mediated signal transduction are critical for the recruitment of effector immune cells to the site of inflammation. This gene is expressed at high levels in primary neutrophils and primary monocytes, and is further upregulated on neutrophil activation and during monocyte to macrophage differentiation. The function of this gene is unknown. This gene is mapped to the region where the chemokine receptor gene cluster is located. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 07, 2023

The c.751C>G (p.L251V) alteration is located in exon 2 (coding exon 2) of the CCRL2 gene. This alteration results from a C to G substitution at nucleotide position 751, causing the leucine (L) at amino acid position 251 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
