The NM_002990.5(CCL22):c.183G>A (p.Pro61Pro) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a cumulative frequency of 0.00103 (AC=1,666) in the gnomAD database across 1,614,030 control chromosomes, including 1 homozygote. The grpmax filtering allele frequency (95% CI) is 0.00131. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Benign/Likely Benign (★).

Genes affected

CCL22 (HGNC:10621): (C-C motif chemokine ligand 22) This antimicrobial gene is one of several Cys-Cys (CC) cytokine genes clustered on the q arm of chromosome 16. Cytokines are a family of secreted proteins involved in immunoregulatory and inflammatory processes. The CC cytokines are proteins characterized by two adjacent cysteines. The cytokine encoded by this gene displays chemotactic activity for monocytes, dendritic cells, natural killer cells and for chronically activated T lymphocytes. It also displays a mild activity for primary activated T lymphocytes and has no chemoattractant activity for neutrophils, eosinophils and resting T lymphocytes. The product of this gene binds to chemokine receptor CCR4. This chemokine may play a role in the trafficking of activated T lymphocytes to inflammatory sites and other aspects of activated T lymphocyte physiology. [provided by RefSeq, Sep 2014]

Classification according to ACMG Germline Pathogenicity v2019

Classification was made for transcript:

Our verdict: Benign. The variant received -7 points.

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	BP4Computational evidence suggests no impact		Computational evidence supports benign — no pathogenic computational or splicing signal (BP4); Splicing verdict: benign (Strong).; Germline computational verdict: benign (Strong).
	BP6Reputable source reports benign		ClinVar 1-star benign — moderate (BP6); ClinVar germline classification: Benign/Likely Benign, 1 star(s).
	BP7Synonymous variant, no splicing impact		Synonymous variant at non-conserved position with no predicted splicing impact (BP7); Synonymous at non-conserved position, no splicing concern — benign (BP7).
