The NM_001007033.2(CLEC6A):c.295G>A (p.Val99Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a cumulative frequency of 0.000000684 (AC=1) in the gnomAD database across 1,461,792 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.0000655. Note: a gnomAD entry for this variant shows a statistical allele-bias signature, consistent with mosaic/somatic contamination (e.g. age-related clonal hematopoiesis) rather than true inherited population frequency — this frequency should not be read as evidence of a common, benign germline variant. In-silico predictor (REVEL) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.V99A: Uncertain_significance (ClinVar VariationId 4229804, 1 star); p.V99F: Likely_benign (ClinVar VariationId 2623059, 1 star)

Genes affected

CLEC6A (HGNC:14556): (C-type lectin domain containing 6A) The protein encoded by this gene is a type II membrane receptor with an extracellular C-type lectin-like domain fold. The extracellular portion binds structures with a high mannose content and has been shown to recognize several pathogens, including C. elegans, S. cerevisiae, M. tuberculosis, C. neoformans, and house dust mite. When stimulated, the encoded protein initiates signalling through the CARD9-Bcl10-Malt1 pathway, leading to the induction of cytokines. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2015]

Classification according to ACGS-UK Somatic Oncogenicity v2025

Classification was made for transcript:

Our verdict: Uncertain_significance. The variant received 1 points.

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	O3Absent or very rare in population		Absent or extremely rare in gnomAD (AC ≤ 2) — O3 moderate; GnomAD: AF = 0.000065, AC = 1 — absent/extremely rare (O3 moderate [+2])
	B3Computational evidence does not support deleterious effect		Computational evidence does not support a deleterious effect; Missense variant — primary computational scorer does not support an oncogenic/deleterious effect; supports B3
