Variant summary

Our verdict is Benign. Variant got -13 ACMG points: 0P and 13B. BP4_Strong BP6 BA1

The NM_002983.3(CCL3):​c.234G>T​(p.Glu78Asp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00595 in 1,613,780 control chromosomes in the GnomAD database, including 311 homozygotes. In-silico tool predicts a benign outcome for this variant. 11/16 in silico tools predict a benign outcome for this variant. Variant has been reported in Lovd as Likely benign (no stars). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Likely benign in UniProt.

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)

ACMG classification

Verdict is Benign. Variant got -13 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0017627776).
• BP6: Variant 17-36088717-C-A is Benign according to our data. Variant chr17-36088717-C-A is described in Lovd as [Likely_benign].
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.0762 is higher than 0.05.
