VCEP Guidelines
Applied ACMG/AMP Criteria
PVS1
PVS1 (Not Applied)
Strength Modified
According to standard ACMG guidelines, the rule for PVS1 is: "Null variant in a gene where loss of function (LoF) is a known mechanism of disease (e.g., nonsense, frameshift, canonical ±1 or 2 splice sites, initiation codon, single exon deletion in a LoF gene)". The evidence for this variant shows: it is a synonymous change (Y95=) that does not introduce a null effect. Therefore, this criterion is not applied.
PS1
PS1 (Not Applied)
Strength Modified
According to standard ACMG guidelines, the rule for PS1 is: "Same amino acid change as a known pathogenic variant but different nucleotide change". The evidence for this variant shows: it does not alter the amino acid (synonymous). Therefore, this criterion is not applied.
PS2
PS2 (Not Applied)
Strength Modified
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 information is available. Therefore, this criterion is not applied.
PS3
PS3 (Not Applied)
Strength Modified
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 studies have been performed. Therefore, this criterion is not applied.
PS4
PS4 (Not Applied)
Strength Modified
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 data. Therefore, this criterion is not applied.
PM1
PM1 (Not Applied)
Strength Modified
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: it is a synonymous variant outside any known domain. Therefore, this criterion is not applied.
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: gnomAD MAF = 0.000398%, meeting the threshold for PM2. Therefore, this criterion is applied at Moderate strength because the variant is extremely rare.
PM3
PM3 (Not Applied)
Strength Modified
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 data available. Therefore, this criterion is not applied.
PM4
PM4 (Not Applied)
Strength Modified
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 length change. Therefore, this criterion is not applied.
PM5
PM5 (Not Applied)
Strength Modified
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 synonymous. Therefore, this criterion is not applied.
PM6
PM6 (Not Applied)
Strength Modified
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 data. Therefore, this criterion is not applied.
PP1
PP1 (Not Applied)
Strength Modified
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.
PP2
PP2 (Not Applied)
Strength Modified
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 synonymous. Therefore, this criterion is not applied.
PP3
PP3 (Not Applied)
Strength Modified
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: computational tools and SpliceAI predict no impact. Therefore, PP3 is not applied and instead BP4 is applied.
PP4
PP4 (Not Applied)
Strength Modified
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. Therefore, this criterion is not applied.
PP5
PP5 (Not Applied)
Strength Modified
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. Therefore, this criterion is not applied.
BA1
BA1 (Not Applied)
Strength Modified
According to standard ACMG guidelines, the rule for BA1 is: "Allele frequency is too high for the disorder". The evidence for this variant shows: MAF is very low. Therefore, this criterion is not applied.
BS1
BS1 (Not Applied)
Strength Modified
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: MAF is below expected. Therefore, this criterion is not applied.
BS2
BS2 (Not Applied)
Strength Modified
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 clear healthy genotype–phenotype correlation. Therefore, this criterion is not applied.
BS3
BS3 (Not Applied)
Strength Modified
According to standard ACMG guidelines, the rule for BS3 is: "Well-established functional studies show no damaging effect". The evidence for this variant shows: no functional assays. Therefore, this criterion is not applied.
BS4
BS4 (Not Applied)
Strength Modified
According to standard ACMG guidelines, the rule for BS4 is: "Lack of segregation in affected family members". The evidence for this variant shows: no family data. Therefore, this criterion is not applied.
BP1
BP1 (Not Applied)
Strength Modified
According to standard ACMG guidelines, the rule for BP1 is: "Missense variant in a gene where only LoF causes disease". The evidence for this variant shows: it is synonymous. Therefore, this criterion is not applied.
BP2
BP2 (Not Applied)
Strength Modified
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
BP3 (Not Applied)
Strength Modified
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 synonymous. Therefore, this criterion is not applied.
BP4
