VCEP Guidelines

Applied ACMG/AMP Criteria (VCEP Specific)

Filter Criteria:
PVS1

PVS1 (Not Applied)

According to VCEP guidelines, the rule for PVS1 is: "Use ATM PVS1 Decision Tree Modification Type: Gene-specific,Strength". The evidence for this variant shows: it is a missense change (N3044S) that does not introduce a null effect. Therefore, this criterion is not applied.

PS1

PS1 (Not Applied)

According to VCEP guidelines, the rule for PS1 is: "Strong Use for protein changes as long as splicing is ruled-out for both alterations". The evidence for this variant shows: no other established pathogenic variant produces the same amino acid change N3044S. Therefore, this criterion is not applied.

PS2

PS2 (Not Applied)

According to standard ACMG guidelines, the rule for PS2 is: "De novo (both maternity and paternity confirmed) in a patient with the disease and no family history". The evidence for this variant shows: no de novo data are available. Therefore, this criterion is not applied.

PS3

PS3 (Not Applied)

According to VCEP guidelines, the rule for PS3 is: "Moderate Strength: Use when a variant fails to rescue both an ATM specific feature (e.g. phosphorylation of ATM-specific targets) AND radiosensitivity". The evidence for this variant shows: no functional studies have been performed. Therefore, this criterion is not applied.

PS4

PS4 (Not Applied)

According to VCEP guidelines, the rule for PS4 is: "Strong Strength: Strong Case-control studies; p-value ≤.05 AND (Odds ratio, hazard ratio, or relative risk ≥2 OR lower 95% CI ≥1.5)". The evidence for this variant shows: no case-control or enrichment data. Therefore, this criterion is not applied.

PM1

PM1 (Not Applied)

According to VCEP guidelines, the rule for PM1 is: "Use for variants located in critical functional domains or hotspots" (gene-specific). The evidence for this variant shows: N3044 is not located in a defined ATM hotspot or well‐characterized functional domain. Therefore, this criterion is not applied.

PM2

PM2 (Supporting)

According to VCEP guidelines, the rule for PM2 is: "Supporting Strength: Frequency ≤.001% if n=1 in a single sub population, that is sufficiently rare and PM2_supporting would apply". The evidence for this variant shows: it is absent from gnomAD and other control databases. Therefore, this criterion is applied at Supporting strength.

PM3

PM3 (Not Applied)

According to VCEP guidelines, the rule for PM3 is: "Use ATM PM3/BP2 table for recessive inheritance". The evidence for this variant shows: no evidence of trans or cis compound heterozygosity. Therefore, this criterion is not applied.

PM4

PM4 (Not Applied)

According to VCEP guidelines, the rule for PM4 is: "Moderate Strength: Use for stop-loss variants". The evidence for this variant shows: it is a missense change, not a stop-loss or frameshift. Therefore, this criterion is not applied.

PM5

PM5 (Not Applied)

According to VCEP guidelines, the rule for PM5 is: "Supporting Strength: Use for genomic frameshift and truncating variants with PTC upstream of p.R3047". The evidence for this variant shows: it is a missense variant at N3044, with no other known pathogenic missense at this residue. Therefore, this criterion is not applied.

PM6

PM6 (Not Applied)

According to standard ACMG guidelines, the rule for PM6 is: "Assumed de novo, but without confirmation of paternity and maternity". The evidence for this variant shows: no de novo assumption data are available. Therefore, this criterion is not applied.

PP1

PP1 (Not Applied)

According to standard ACMG guidelines, the rule for PP1 is: "Cosegregation with disease in multiple affected family members". The evidence for this variant shows: no segregation data are available. Therefore, this criterion is not applied.

PP2

PP2 (Not Applied)

According to standard ACMG guidelines, the rule for PP2 is: "Missense variant in a gene with low rate of benign missense variation". The evidence for this variant shows: ATM tolerates missense changes and has known benign missense. Therefore, this criterion is not applied.

PP3

PP3 (Supporting)

According to VCEP guidelines, the rule for PP3 is: "Supporting Strength: Protein: REVEL >.7333; RNA: At least one well-established in silico predictor shows impact on splicing". The evidence for this variant shows: a REVEL score of 0.87, exceeding 0.7333, and multiple damaging predictions. Therefore, this criterion is applied at Supporting strength.

PP4

PP4 (Not Applied)

According to standard ACMG guidelines, the rule for PP4 is: "Patient's phenotype or family history is highly specific for a disease with a single genetic etiology". The evidence for this variant shows: no specific phenotype data provided. Therefore, this criterion is not applied.

PP5

PP5 (Not Applied)

According to standard ACMG guidelines, the rule for PP5 is: "Reputable source recently reports variant as pathogenic". The evidence for this variant shows: ClinVar asserts VUS only. Therefore, this criterion is not applied.

BA1

BA1 (Not Applied)

According to VCEP guidelines, the rule for BA1 is: "Stand Alone Strength: Filtering Allele Frequency >.5%". The evidence for this variant shows: absent from population databases. Therefore, this criterion is not applied.

BS1

BS1 (Not Applied)

According to VCEP guidelines, the rule for BS1 is: "Strong Strength: Filtering Allele Frequency >.05%". The evidence for this variant shows: absent from control databases. Therefore, this criterion is not applied.

BS2

BS2 (Not Applied)

According to standard ACMG guidelines, the rule for BS2 is: "Observed in a healthy adult individual for a dominant disorder". The evidence for this variant shows: no such observations. Therefore, this criterion is not applied.

BS3

BS3 (Not Applied)

According to VCEP guidelines, the rule for BS3 is: "Moderate Strength: Use when a variant rescues both an ATM specific feature AND radiosensitivity". The evidence for this variant shows: no functional assays demonstrating rescue. Therefore, this criterion is not applied.

BS4

BS4 (Not Applied)

According to standard ACMG guidelines, the rule for BS4 is: "Lack of segregation in affected members of a family". The evidence for this variant shows: no segregation studies. Therefore, this criterion is not applied.

BP1

BP1 (Not Applied)

According to standard ACMG guidelines, the rule for BP1 is: "Missense variant in a gene where only truncating variants cause disease". The evidence for this variant shows: ATM has pathogenic missense variants. Therefore, this criterion is not applied.

BP2

BP2 (Not Applied)

According to VCEP guidelines, the rule for BP2 is: "Use ATM PM3/BP2 table". The evidence for this variant shows: no evidence of cis-trans relationships affecting pathogenicity. Therefore, this criterion is not applied.

BP3

BP3 (Not Applied)

According to standard ACMG guidelines, the rule for BP3 is: "In-frame indels in repetitive regions". The evidence for this variant shows: it is a single nucleotide substitution. Therefore, this criterion is not applied.

BP4

BP4 (Not Applied)

According to VCEP guidelines, the rule for BP4 is: "Supporting Strength: Protein Analysis: Metapredictor REVEL score ≤.249". The evidence for this variant shows: REVEL is 0.87, which exceeds the benign threshold. Therefore, this criterion is not applied.
