VCEP Guidelines

Applied ACMG/AMP Criteria (VCEP Specific)

Filter Criteria:
PVS1

PVS1 (Not Applied)

According to standard ACMG guidelines, the rule for PVS1 is: 'Null variant (nonsense, frameshift, canonical ±1 or 2 splice sites, initiation codon, single exon or multi-exon deletion) in a gene where loss of function is a known mechanism of disease.' The evidence for this variant shows: it is a synonymous change (p.Ser1343=) that does not introduce a premature stop codon or disrupt canonical splice sites. Therefore, this criterion is not applied at Not Applied strength because the variant is not a null variant.

PS1

PS1 (Not Applied)

According to standard ACMG guidelines, the rule for PS1 is: 'Same amino acid change as a previously established pathogenic variant regardless of nucleotide change.' The evidence for this variant shows: it is synonymous and does not change the amino acid. Therefore, this criterion is not applied at Not Applied strength because there is no amino acid change matching a known pathogenic variant.

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 at Not Applied strength due to lack of de novo confirmation.

PS3

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 at Not Applied strength because functional data are missing.

PS4

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 or affected individual data. Therefore, this criterion is not applied at Not Applied strength due to absence of case prevalence data.

PM1

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: location in CUX1 has no known mutational hot spot or critical domain. Therefore, this criterion is not applied at Not Applied strength because no such domain evidence exists.

PM2

PM2 (Moderate)

According to standard ACMG guidelines, the rule for PM2 is: 'Absent from controls (or at extremely low frequency if recessive) in population databases.' The evidence for this variant shows: MAF=0.013% in gnomAD (18/138,438 alleles, no homozygotes). Therefore, this criterion is applied at Moderate strength because the variant is extremely rare.

PM3

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 information on trans configuration. Therefore, this criterion is not applied at Not Applied strength due to missing trans data.

PM4

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 synonymous with no protein length change. Therefore, this criterion is not applied at Not Applied strength.

PM5

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 not a missense change. Therefore, this criterion is not applied at Not Applied strength.

PM6

PM6 (Not Applied)

According to standard ACMG guidelines, the rule for PM6 is: 'Assumed de novo, without confirmation of paternity and maternity.' The evidence for this variant shows: no information on de novo status. Therefore, this criterion is not applied at Not Applied strength.

PP1

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. Therefore, this criterion is not applied at Not Applied strength due to lack of family data.

PP2

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 where missense variants are a common mechanism of disease.' The evidence for this variant shows: it is synonymous, not missense. Therefore, this criterion is not applied at Not Applied strength.

PP3

PP3 (Not Applied)

According to standard ACMG guidelines, the rule for PP3 is: 'Multiple lines of computational evidence support a deleterious effect.' The evidence for this variant shows: in silico predictors (CADD=1.13, SpliceAI=0) indicate no impact. Therefore, this criterion is not applied at Not Applied strength because computational evidence does not support deleterious effect.

PP4

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 phenotype data provided. Therefore, this criterion is not applied at Not Applied strength.

PP5

PP5 (Not Applied)

According to standard ACMG guidelines, the rule for PP5 is: 'Reputable source reports variant as pathogenic without accessible evidence.' The evidence for this variant shows: no such report exists. Therefore, this criterion is not applied at Not Applied strength.

BA1

BA1 (Not Applied)

According to standard ACMG guidelines, the rule for BA1 is: 'Allele frequency is too high for disorder (stand-alone benign evidence).' The evidence for this variant shows: MAF=0.013%, which is well below BA1 threshold. Therefore, this criterion is not applied at Not Applied strength.

BS1

BS1 (Not Applied)

According to standard ACMG guidelines, the rule for BS1 is: 'Allele frequency is greater than expected for disorder.' The evidence for this variant shows: MAF=0.013% is not greater than expected. Therefore, this criterion is not applied at Not Applied strength.

BS2

BS2 (Not Applied)

According to standard ACMG guidelines, the rule for BS2 is: 'Observed in healthy adult individuals for dominant/X-linked/mitochondrial disorders with full penetrance expected at an early age.' The evidence for this variant shows: no healthy control observations with phenotype data. Therefore, this criterion is not applied at Not Applied strength.

BS3

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 performed. Therefore, this criterion is not applied at Not Applied strength.

BS4

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 analysis. Therefore, this criterion is not applied at Not Applied strength.

BP1

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 synonymous, not missense. Therefore, this criterion is not applied at Not Applied strength.

BP2

BP2 (Not Applied)

According to standard ACMG guidelines, the rule for BP2 is: 'Observed in trans with a pathogenic variant for a dominant disorder or in cis with a pathogenic variant.' The evidence for this variant shows: no phase data available. Therefore, this criterion is not applied at Not Applied strength.

BP3

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 not an in-frame indel. Therefore, this criterion is not applied at Not Applied strength.

BP4

BP4 (Supporting)

According to standard ACMG guidelines, the rule for BP4 is: 'Multiple lines of computational evidence suggest no impact on gene or gene product.' The evidence for this variant shows: CADD=1.13 and SpliceAI=0 predict no impact on protein function or splicing. Therefore, this criterion is applied at Supporting strength because computational tools consistently indicate benign effect.

BP5

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 alternate molecular basis reported. Therefore, this criterion is not applied at Not Applied strength.

BP6

BP6 (Not Applied)

According to standard ACMG guidelines, the rule for BP6 is: 'Reputable source reports variant as benign without accessible evidence.' The evidence for this variant shows: no such report exists. Therefore, this criterion is not applied at Not Applied strength.

BP7

BP7 (Supporting)

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 synonymous change (p.Ser1343=) and SpliceAI predicts no splicing impact. Therefore, this criterion is applied at Supporting strength because it meets the definition of a silent variant with no splicing effect.
