Genes affected

CCR5 (HGNC:1606): (C-C motif chemokine receptor 5) This gene encodes a member of the beta chemokine receptor family, which is predicted to be a seven transmembrane protein similar to G protein-coupled receptors. This protein is expressed by T cells and macrophages, and is known to be an important co-receptor for macrophage-tropic virus, including HIV, to enter host cells. Defective alleles of this gene have been associated with the HIV infection resistance. The ligands of this receptor include monocyte chemoattractant protein 2 (MCP-2), macrophage inflammatory protein 1 alpha (MIP-1 alpha), macrophage inflammatory protein 1 beta (MIP-1 beta) and regulated on activation normal T expressed and secreted protein (RANTES). Expression of this gene was also detected in a promyeloblastic cell line, suggesting that this protein may play a role in granulocyte lineage proliferation and differentiation. This gene is located at the chemokine receptor gene cluster region. An allelic polymorphism in this gene results in both functional and non-functional alleles; the reference genome represents the functional allele. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2015]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.75).
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0132 (2016/152260) while in subpopulation AFR AF = 0.0454 (1887/41540). AF 95% confidence interval is 0.0437. There are 47 homozygotes in GnomAd4. There are 906 alleles in the male GnomAd4 subpopulation. Median coverage is 30. This position passed quality control check.
• BS2: High AC in GnomAd4 at 2016 AD gene.
