Genes affected

(HGNC:):

CCL5 (HGNC:10632): (C-C motif chemokine ligand 5) This gene is one of several chemokine genes clustered on the q-arm of chromosome 17. Chemokines form a superfamily of secreted proteins involved in immunoregulatory and inflammatory processes. The superfamily is divided into four subfamilies based on the arrangement of the N-terminal cysteine residues of the mature peptide. This chemokine, a member of the CC subfamily, functions as a chemoattractant for blood monocytes, memory T helper cells and eosinophils. It causes the release of histamine from basophils and activates eosinophils. This cytokine is one of the major HIV-suppressive factors produced by CD8+ cells. It functions as one of the natural ligands for the chemokine receptor chemokine (C-C motif) receptor 5 (CCR5), and it suppresses in vitro replication of the R5 strains of HIV-1, which use CCR5 as a coreceptor. Alternative splicing results in multiple transcript variants that encode different isoforms. [provided by RefSeq, Jul 2013]

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• PP5: Variant 17-35880401-G-C is Pathogenic according to our data. Variant chr17-35880401-G-C is described in ClinVar as [Pathogenic]. Clinvar id is 12739.Status of the report is no_assertion_criteria_provided, 0 stars.
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.85). . Strength limited to SUPPORTING due to the PP5.
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.105 is higher than 0.05.
