VCEP Guidelines
Applied ACMG/AMP Criteria (VCEP Specific)
PVS1 (Very Strong)
According to standard ACMG guidelines, the rule for PVS1 is: "Null variant (nonsense, frameshift, canonical ±1 or 2 splice sites, initiation codon, single exon deletion) in a gene where loss of function is a known mechanism of disease". The evidence for this variant shows: it is a nonsense variant (p.Q572*) in POLE, and loss of function is a known disease mechanism. Therefore, this criterion is applied at Very Strong strength because it leads to a premature stop codon and predicted loss of function.
PS1 (Not Applied)
According to standard ACMG guidelines, the rule for PS1 is: "Same amino acid change as a known pathogenic variant via different nucleotide change". The evidence for this variant shows: no known pathogenic variant affects the same amino acid Q572. Therefore, this criterion is not applied.
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 parental testing data are available. Therefore, this criterion is not applied.
PS3 (Not Applied)
According to standard ACMG guidelines, the rule for PS3 is: "Well-established functional studies supportive of a damaging effect on the gene or gene product". The evidence for this variant shows: no functional characterization has been performed. Therefore, this criterion is not applied.
PS4 (Not Applied)
According to standard ACMG guidelines, the rule for PS4 is: "Prevalence in affected individuals significantly increased compared with controls". The evidence for this variant shows: no case-control prevalence data are available. Therefore, this criterion is not applied.
PM1 (Not Applied)
According to standard ACMG guidelines, the rule for PM1 is: "Located in a mutational hot spot or well-established functional domain without benign variation". The evidence for this variant shows: position Q572 is not known as a mutational hotspot or critical domain. Therefore, this criterion is not applied.
PM2 (Moderate)
According to standard ACMG guidelines, the rule for PM2 is: "Absent from controls (or at extremely low frequency if recessive)". The evidence for this variant shows: it is absent from gnomAD and other population databases. Therefore, this criterion is applied at Moderate strength because the variant is not observed in population controls.
PM3 (Not Applied)
According to standard ACMG guidelines, the rule for PM3 is: "Detected in trans with a pathogenic variant (for recessive disorders)". The evidence for this variant shows: no trans-phase data are available and POLE-associated disease is autosomal dominant. Therefore, this criterion is not applied.
PM4 (Not Applied)
According to standard ACMG guidelines, the rule for PM4 is: "Protein length changes due to in-frame deletions/insertions or stop-loss variants". The evidence for this variant shows: it is a stop-gain, not an in-frame indel or stop-loss. Therefore, this criterion is not applied.
PM5 (Not Applied)
According to standard ACMG guidelines, the rule for PM5 is: "Novel missense change at an amino acid residue where a different pathogenic missense change has been seen". The evidence for this variant shows: it is a nonsense change, not a missense. Therefore, this criterion is not applied.
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 parental testing data are provided. Therefore, this criterion is not applied.
PP1 (Not Applied)
According to standard ACMG guidelines, the rule for PP1 is: "Co-segregation 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 (Not Applied)
According to standard ACMG guidelines, the rule for PP2 is: "Missense variant in a gene with a low rate of benign missense variation and where missense variants are a common mechanism of disease". The evidence for this variant shows: it is a nonsense variant, not a missense. Therefore, this criterion is not applied.
PP3 (Not Applied)
According to standard ACMG guidelines, the rule for PP3 is: "Multiple lines of computational evidence support a deleterious effect on the gene/gene product". The evidence for this variant shows: computational tools predict mixed benign impact and do not reliably support damage. Therefore, this criterion is not applied.
PP4 (Not Applied)
According to standard ACMG guidelines, the rule for PP4 is: "Patient’s phenotype or family history highly specific for a disease with a single genetic etiology". The evidence for this variant shows: no detailed phenotype information is provided. Therefore, this criterion is not applied.
PP5 (Not Applied)
According to standard ACMG guidelines, the rule for PP5 is: "Reputable source reports variant as pathogenic, but without accessible evidence". The evidence for this variant shows: no such reports exist. Therefore, this criterion is not applied.
BA1 (Not Applied)
According to standard ACMG guidelines, the rule for BA1 is: "Allele frequency is too high for the disorder". The evidence for this variant shows: allele frequency is 0%. Therefore, this criterion is not applied.
BS1 (Not Applied)
According to standard ACMG guidelines, the rule for BS1 is: "Allele frequency is greater than expected for the disorder". The evidence for this variant shows: it is absent from population databases. Therefore, this criterion is not applied.
BS2 (Not Applied)
According to standard ACMG guidelines, the rule for BS2 is: "Observed in healthy individuals with full penetrance expected at an early age". The evidence for this variant shows: no such observations exist. Therefore, this criterion is not applied.
BS3 (Not Applied)
According to standard ACMG guidelines, the rule for BS3 is: "Well-established functional studies show no damaging effect on protein function or splicing". The evidence for this variant shows: no functional studies are available. Therefore, this criterion is not applied.
BS4 (Not Applied)
According to standard ACMG guidelines, the rule for BS4 is: "Lack of segregation in affected family members". The evidence for this variant shows: no segregation data. Therefore, this criterion is not applied.
BP1 (Not Applied)
According to standard ACMG guidelines, the rule for BP1 is: "Missense variant in a gene where only loss‐of‐function causes disease". The evidence for this variant shows: it is truncating, not missense. Therefore, this criterion is not applied.
BP2 (Not Applied)
According to standard ACMG guidelines, the rule for BP2 is: "Observed in trans with a pathogenic variant for dominant disorders or in cis with a pathogenic variant". The evidence for this variant shows: no such observations. Therefore, this criterion is not applied.
BP3 (Not Applied)
According to standard ACMG guidelines, the rule for BP3 is: "In-frame deletions/insertions in a repetitive region without known function". The evidence for this variant shows: it is a nonsense variant, not an in-frame indel. Therefore, this criterion is not applied.
BP4 (Not Applied)
According to standard ACMG guidelines, the rule for BP4 is: "Multiple lines of computational evidence suggest no impact". The evidence for this variant shows: while computational predictors are mixed, the variant is a truncating change predicted to disrupt function. Therefore, this criterion is not applied.
BP5 (Not Applied)
According to standard ACMG guidelines, the rule for BP5 is: "Variant found in a case with an alternate molecular basis for disease". The evidence for this variant shows: no such cases are reported. Therefore, this criterion is not applied.
BP6 (Not Applied)
According to standard ACMG guidelines, the rule for BP6 is: "Reputable source reports variant as benign, but without accessible evidence". The evidence for this variant shows: no such reports exist. Therefore, this criterion is not applied.
BP7 (Not Applied)
According to standard ACMG guidelines, the rule for BP7 is: "Synonymous variant with no predicted impact on splicing". The evidence for this variant shows: it is a nonsense variant, not synonymous. Therefore, this criterion is not applied.
