VCEP Guidelines
Applied ACMG/AMP Criteria (VCEP Specific)
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 deletion) in a gene where loss of function is a known mechanism of disease'. The evidence for this variant shows: it is an intronic change at +29 and not predicted to affect canonical splice sites. Therefore, this criterion is not applied because the variant is not a null variant in a LoF gene.
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: no amino acid change is described and no matching pathogenic missense variant exists. Therefore, this criterion is not applied because there is no amino acid change matching a known pathogenic variant.
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 or parental testing data are available. Therefore, this criterion is not applied due to lack of de novo evidence.
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 studies have been performed. Therefore, this criterion is not applied due to absence of functional data.
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 patient frequency data are available. Therefore, this criterion is not applied due to lack of case frequency data.
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 and functional domain are unknown and not in a known hotspot. 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: MAF = 0.00318% in gnomAD (1/31398 alleles, no homozygotes), which is extremely low. Therefore, this criterion is applied at Moderate strength because the variant is rare in population databases.
PM3 (Not Applied)
According to standard ACMG guidelines, the rule for PM3 is: 'Detected in trans with a pathogenic variant for a recessive disorder'. The evidence for this variant shows: no data on trans phase with any pathogenic variant. 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: no predicted change in protein length (intronic variant). 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: no missense change or prior pathogenic variant at this residue. 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 de novo or parental data. 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 intronic, not 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 or gene product'. The evidence for this variant shows: CADD score of 0.09, SpliceAI score = 0, and other in silico tools predict benign. 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 phenotype or clinical data 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: not present in ClinVar or other databases. Therefore, this criterion is not applied.
BA1 (Not Applied)
According to standard ACMG guidelines, the rule for BA1 is: 'Allele frequency is >5% in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium'. The evidence for this variant shows: MAF = 0.00318%, well below 5%. 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: frequency is very low and not above expected thresholds. Therefore, this criterion is not applied.
BS2 (Not Applied)
According to standard ACMG guidelines, the rule for BS2 is: 'Observed in a healthy adult individual for a dominant disorder with full penetrance expected at an early age'. The evidence for this variant shows: no data on healthy adults carrying this variant. 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 available. Therefore, this criterion is not applied due to lack of functional data.
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 studies performed. 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: intronic change, 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 a dominant disorder or in cis with a pathogenic variant'. The evidence for this variant shows: no phase information with other variants. 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: not an in-frame indel. Therefore, this criterion is not applied.
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 score of 0.09, SpliceAI score = 0, and other in silico tools predict benign. Therefore, this criterion is applied at Supporting strength because computational evidence supports no deleterious effect.
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 case reports with alternate diagnosis. 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: not reported in databases as benign. 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: intronic, not synonymous. Therefore, this criterion is not applied.
