Classification rationale
Interpretation summary
Generated evidence synthesis
1
Pathogenic: PS1 Strong is supported by the PTEN Expert Panel's Pathogenic classification of p.Arg130Gln.
2
Pathogenic: PS3 Moderate is supported by the high-confidence phosphatase score of -2.04016411.
3
Pathogenic: PM1 Moderate is supported because Arg130 lies in the VCEP-defined catalytic-motif interval 123-130.
4
Pathogenic: PM2 Supporting is supported by gnomAD v4.1 allele frequency of 1.23924e-06.
5
Pathogenic: PP2 Supporting applies to this PTEN missense variant under the VCEP rule.
6
Pathogenic: PP3 Supporting is supported by the REVEL score of 0.976.
Final determination:
Under the PTEN VCEP v3.2 framework, Rule7 is satisfied by one Strong pathogenic criterion, two Moderate pathogenic criteria, and at least two Supporting pathogenic criteria, producing a Pathogenic call.
Criteria assessment
ACMG/AMP criteria review
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: p.Arg130Gln is a missense substitution, whereas the PTEN PVS1 decision tree has no missense path and assigns PVS1 only to specified loss-of-function variant classes. |

|
| PS1 | Met | Met at Strong: the exact p.Arg130Gln variant is recorded as Pathogenic by the PTEN Expert Panel, satisfying the same-amino-acid-change rule. |
cspec
clinvar
|
| PS2 | Not assessed | Not assessed: de novo claims lack a verified primary case report documenting phenotype, no family history, and confirmed maternity and paternity. |
clinvar
|
| PS3 | Met | Met at Moderate: the high-confidence PTEN phosphatase assay score is -2.04016411, below the VCEP PS3 threshold of ≤ -1.11. |

|
| PS4 | Not assessed | Not assessed: no variant-specific case-control counts or odds ratio, and no Cleveland Clinic or pediatric phenotype-specificity scores, are available for the PS4 rule. |

|
| PM1 | Met | Met at Moderate: p.Arg130Gln is residue 130, within the VCEP-defined catalytic-motif interval 123-130. |
cspec
|
| PM2 | Met | Met at Supporting: gnomAD v4.1 total AF 1.23924e-06 and highest subpopulation AF 1.69511e-06 are below the PTEN VCEP PM2 thresholds. |
cspec

|
| PM3 | N/A | Not applicable: the PTEN VCEP specification explicitly marks PM3 as not applicable. |
cspec
|
| PM4 | N/A | Not applicable: p.Arg130Gln changes one amino acid without altering protein length, so it does not meet the PTEN VCEP PM4 insertion/deletion or stop-loss rule. |
cspec
pvs1_variant_assessment
|
| PM5 | Not assessed | Not assessed: zero same-residue comparator candidates and no qualifying BLOSUM62 comparison are available. |

|
| PM6 | Not assessed | Not assessed: reported de novo observations lack verified counts, proband details, family-history status, and parental-testing status for the VCEP thresholds. |
clinvar
|
| PP1 | Not assessed | Not assessed: no verified affected relatives, cosegregation observations, or informative meiosis count are available. |
|
| PP2 | Met | Met at Supporting: the VCEP marks PP2 applicable for this missense PTEN variant under its low-benign-missense and common-missense-mechanism rule. |
cspec
|
| PP3 | Met | Met: missense REVEL score 0.976 exceeds the PTEN VCEP PP3 cutoff of >0.7. |
cspec

|
| PP4 | N/A | Not applicable: the PTEN VCEP incorporates phenotype specificity into PS4 Use 2 rather than permitting PP4. |
cspec
