Variant summary
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)

Classification according to ACMG Germline Pathogenicity v2019
Our verdict: Uncertain_significance. The variant received 0 points.
| Apply | Criterion Code & Title / Strength | Rationale / Clinical Context | |
|---|---|---|---|
| PM2Absent/extremely low in population databases | Very rare in gnomAD for AR/unknown gene (popmax AF < threshold/10) — PM2; GnomAD popmax AF = 0.0000655 — very rare for unknown gene (threshold 0.001) — PM2 moderate. | ||
| BP4Computational evidence suggests no impact | Computational evidence supports benign — no pathogenic computational or splicing signal (BP4); Splicing verdict: benign (Strong).; Germline computational verdict: benign (Moderate). |
