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.
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.
cspec vcep_pvs1_decisiontree_pten pvs1_variant_assessment
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.
cspec vcep_mmc2 PMID:29706350 PMID:32350270
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.
cspec gnomad_v4 PMID:32350270 PMID:28572459
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 gnomad_v4
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.
cspec pm5_candidates
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 revel
PP4 N/A Not applicable: the PTEN VCEP incorporates phenotype specificity into PS4 Use 2 rather than permitting PP4.
cspec
PP5 Met Not applicable: the PTEN VCEP explicitly prohibits PP5 use regardless of available pathogenic assertions.
cspec clinvar
BA1 Not met Not met: gnomAD v4.1 total allele frequency is 1.23924e-06, below the PTEN VCEP BA1 threshold of >0.00056.
cspec gnomad_v4
BS1 Not met Not met: gnomAD v4.1 total allele frequency is 1.23924e-06, below the PTEN VCEP BS1 Supporting lower boundary of 0.0000043.
cspec gnomad_v4
BS2 Not met Not met: gnomAD v4.1 reports 0 homozygotes among 1,613,886 alleles, so the required homozygous observation is absent.
cspec gnomad_v4
BS3 Not met Not met: the high-confidence phosphatase score is -2.04016411, not greater than the VCEP BS3_Supporting requirement of > 0.
cspec vcep_mmc2 PMID:29706350
BS4 Not assessed Not assessed: no affected family members with documented non-segregation are reported for this variant.
BP1 N/A Not applicable: the PTEN VCEP explicitly excludes BP1 for PTEN.
cspec
BP2 Not assessed Not assessed: no documented trans observation or at least three cis/phase-unknown observations with different pathogenic PTEN variants are available.
cspec
BP3 N/A Not applicable: the PTEN VCEP explicitly marks BP3 as Not Applicable, regardless of the variant's missense consequence or repeat-region context.
cspec
BP4 Not met Not met: missense REVEL score 0.976 is above, not below, the PTEN VCEP BP4 cutoff of <0.5.
cspec revel
BP5 Not assessed Not assessed: no two cases with an alternate highly penetrant molecular basis and non-overlapping PTEN history are documented.
cspec
BP6 N/A Not applicable: the PTEN VCEP explicitly prohibits BP6 use regardless of any reputable benign-source assertion.
cspec
BP7 N/A Not applicable: c.389G>A is a missense exonic variant, outside BP7's synonymous or intronic +7/-21 scope.
