Classification rationale
Interpretation summary
Generated evidence synthesis
1
PM2 (Supporting): variant absent from gnomAD v2.1, gnomAD v4.1, and gnomAD-Canada v1.0.
2
PP3 (Supporting): SpliceAI predicts splice-donor loss at the annotated donor position (max delta 0.925, above the 0.8 high-precision tier).
3
Final classification: VUS — under generic ACMG/AMP 2015 rules, two supporting criteria (PM2 and PP3) do not combine to pathogenic or benign.

Criteria shown when status is available
All criteria require review: For research and educational purposes only.
| Criterion | Status | Rationale | Evidence used |
|---|---|---|---|
| PVS1 | N/A | Not applicable: c.3082G>C is a missense substitution, not a null variant class covered by PVS1. |
pvs1_generic_framework
generic_acmg_combination_rules
|
| PS1 | Not assessed | Not assessed: no established pathogenic variant producing the identical p.Asp1028His change via a different nucleotide was found. |
clinvar
|
| PS2 | Not assessed | Not assessed: no parental testing or genotype data were available to evaluate a possible de novo occurrence. |
generic_acmg_combination_rules
|
| PS3 | Not assessed | Not assessed: no functional assay data (kinase, splicing, or cell-based) for this variant were available. |
|
| PS4 | Not assessed | Not assessed: no germline case-control cohort or enrichment statistic was available for this variant. |
|
| PM1 | Not assessed | Not assessed: no germline mutational-hotspot or critical-domain annotation for residue 1028 was available. |
|
| PM2 | Met | Met (Supporting): allele absent from gnomAD v2.1, gnomAD v4.1, and gnomAD-Canada v1.0. |
gnomad_v2
gnomad_v4
gnomad_canada
|
| PM3 | Not assessed | Not assessed: no affected-proband, segregation, or trans-phase data were available. |
|
| PM4 | N/A | Not applicable: missense substitution causes no protein length change, which PM4 requires. |
pvs1_generic_framework
generic_acmg_combination_rules
|
| PM5 | N/A | Not applicable: no pathogenic missense change at codon 1028 was identified for comparison. |
pm5_candidates
|
| PM6 | Not assessed | Not assessed: no documented unconfirmed de novo occurrence was available. |
generic_acmg_combination_rules
|
| PP1 | Not assessed | Not assessed: no familial segregation data were available for this variant. |
generic_acmg_combination_rules
|
| PP2 | Not assessed | Not assessed: no MET missense-constraint metric or curated benign-missense-rate data were available. |
|
| PP3 | Met | Met (Supporting): SpliceAI predicts splice-donor loss at the donor position itself (max delta 0.925, above the 0.8 high-precision cutoff). |

|
| PP4 | Not assessed | Not assessed: no patient phenotype or clinical diagnosis was provided. |
|
| PP5 | Not met | Not met: ClinVar has no record for this exact variant and no expert-panel pathogenic classification. |
clinvar
|
| BA1 | Not met | Not met: allele is absent from gnomAD, so no population frequency approaches the BA1 threshold. |
gnomad_v2
gnomad_v4
gnomad_canada
|
| BS1 | Not met | Not met: absent from gnomAD v2.1, v4.1, and gnomAD-Canada v1.0, so no elevated allele frequency supports BS1. |

|
| BS2 | Not assessed | Not assessed: no observations of the variant in healthy adults or unaffected individuals were documented. |
|
| BS3 | Not assessed | Not assessed: no functional assay evidence showing normal protein function was available. |
|
| BS4 | Not assessed | Not assessed: no affected individual lacking the variant (non-segregation) was documented. |
generic_acmg_combination_rules
|
| BP1 | Not assessed | Not assessed: no citable evidence that MET disease is primarily caused by truncating variants was available. |
|
| BP2 | Not assessed | Not assessed: no observations of this variant in trans or in cis with a pathogenic variant were available. |
|
| BP3 | N/A | Not applicable: missense substitution does not alter protein length in a repetitive region, which BP3 requires. |
pvs1_generic_framework
generic_acmg_combination_rules
|
| BP4 | Not met | Not met: the dominant in-silico signal (SpliceAI donor loss, max delta 0.925) indicates damage, not a benign effect. |
spliceai
revel
bayesdel
|
| BP5 | Not assessed | Not assessed: no clinical phenotype or independent alternate molecular basis for disease was provided. |
|
| BP6 | Not met | Not met: ClinVar has no record for this exact variant and no expert-panel benign classification exists. |
clinvar
|
| BP7 | N/A | Not applicable: BP7 applies only to synonymous variants; this is a missense substitution. |
