Genes affected
CCL3 (HGNC:10627): (C-C motif chemokine ligand 3) This locus represents a small inducible cytokine. The encoded protein, also known as macrophage inflammatory protein 1 alpha, plays a role in inflammatory responses through binding to the receptors CCR1, CCR4 and CCR5. Polymorphisms at this locus may be associated with both resistance and susceptibility to infection by human immunodeficiency virus type 1.[provided by RefSeq, Sep 2010]
CCL3-AS1 (HGNC:55229): (CCL3 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 21, 2023The c.203G>A (p.R68Q) alteration is located in exon 3 (coding exon 3) of the CCL3 gene. This alteration results from a G to A substitution at nucleotide position 203, causing the arginine (R) at amino acid position 68 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
