VCEP Guidelines
Applied ACMG/AMP Criteria (VCEP Specific)
PVS1 (Not Applied)
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 an intronic deletion at position +14, outside of canonical splice sites, with no predicted LoF. Therefore, this criterion is not applied.
PS1 (Not Applied)
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 no amino acid change is produced. 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 data on de novo status. 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 studies have 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 or cohort data in affected individuals. 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 it is intronic at +14, outside known functional domains. 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 a MAF of 0.000864% in gnomAD (2/231502 alleles), consistent with extremely low frequency. Therefore, this criterion is applied at Moderate strength.
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 zygosity or trans configuration. 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 intronic and does not change protein length. 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 not a missense change. 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 data on assumed de novo status. 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 family segregation data. 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 SpliceAI = 0.01 and CADD = –0.28, indicating no predicted deleterious impact. 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 specific phenotype or family history information. 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 ClinVar reports it as benign. 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 a MAF of 0.000864%, which is not above any high-frequency threshold. 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 a very low MAF in gnomAD. 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 data on health status of carriers. 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.
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 family 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 LoF causes disease". The evidence for this variant shows it is intronic. 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 data on phase with any pathogenic variant. 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 not in a repetitive region and is a single nucleotide deletion. 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 SpliceAI = 0.01 and CADD = –0.28, predicting no impact on splicing or protein. Therefore, this criterion is applied at Supporting strength.
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 case report. Therefore, this criterion is not applied.
BP6 (Supporting)
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 ClinVar lists it as Benign with no primary evidence available. Therefore, this criterion is applied at Supporting strength.
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 intronic, not synonymous. Therefore, this criterion is not applied.
