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, start codon, splicing +1/2, startgain, single or multi-exon deletion) in a gene where LOF is a known mechanism of disease." The evidence for this variant shows: it is a synonymous (silent) variant, not predicted to produce a null allele. Therefore, this criterion is not applied.
PS1 (Not Applied)
According to VCEP guidelines the rule for PS1 is: "Strong Same amino acid change as a previously established pathogenic variant regardless of nucleotide change (including analogous residues in HRAS, KRAS, MRAS, NRAS, RIT1, RRAS2)." The evidence for this variant shows: it is a synonymous change (E31=), so no amino acid change. Therefore, this criterion is not applied.
PS2 (Not Applied)
According to VCEP guidelines the rule for PS2 is: "Very Strong if de novo (both maternity and paternity confirmed) or Strong/Moderate if de novo with varying points." The evidence for this variant shows: de novo status is unknown. Therefore, this criterion is not applied.
PS3 (Not Applied)
According to VCEP guidelines the rule for PS3 is: "Moderate if two or more different approved assays show a deleterious effect; Supporting if one approved assay." The evidence for this variant shows: no functional studies have been performed. Therefore, this criterion is not applied.
PS4 (Not Applied)
According to VCEP guidelines the rule for PS4 is: "Strong if ≥5 proband points; Moderate if ≥3; Supporting if ≥1." The evidence for this variant shows: no case‐control or proband data supporting enrichment in affected individuals. Therefore, this criterion is not applied.
PM1 (Not Applied)
According to VCEP guidelines the rule for PM1 is: "Moderate for variants in critical functional domains (P-loop AA10-17, SW1 AA25-40, SW2 AA57-64, SAK AA145-156)." The evidence for this variant shows: it is synonymous and does not alter amino acid sequence within SW1. Therefore, this criterion is not applied.
PM2 (Not Applied)
According to VCEP guidelines the rule for PM2 is: "Supporting: The variant must be absent from controls (gnomAD)." The evidence for this variant shows: it is present in gnomAD at MAF 0.0018%. Therefore, this criterion is not applied.
PM3 (Not Applied)
According to standard ACMG guidelines the rule for PM3 is: "For recessive disorders, detected in trans with a pathogenic variant." The evidence for this variant shows: no evidence of trans configuration in a recessive context. Therefore, this criterion is not applied.
PM4 (Not Applied)
According to VCEP guidelines the rule for PM4 is: "Moderate for protein length changes due to in-frame deletions/insertions outside repetitive regions." The evidence for this variant shows: it is synonymous with no indel. Therefore, this criterion is not applied.
PM5 (Not Applied)
According to VCEP guidelines the rule for PM5 is: "Strong if ≥2 different known pathogenic residue changes at the same codon in ≥5 probands; Moderate if 1 pathogenic residue change." The evidence for this variant shows: it is synonymous and does not change the residue. Therefore, this criterion is not applied.
PM6 (Not Applied)
According to VCEP guidelines the rule for PM6 is: "Strong/Moderate/Supporting for unconfirmed de novo occurrences with varying point values." The evidence for this variant shows: de novo status is unknown. Therefore, this criterion is not applied.
PP1 (Not Applied)
According to VCEP guidelines the rule for PP1 is: "Supporting/Moderate/Strong based on number of informative meioses." The evidence for this variant shows: no segregation data available. Therefore, this criterion is not applied.
PP2 (Not Applied)
According to standard ACMG guidelines the rule for PP2 is: "Supporting for missense variants in a gene with low rate of benign missense variants and where missense is a common mechanism." The evidence for this variant shows: it is synonymous, not missense. Therefore, this criterion is not applied.
PP3 (Not Applied)
According to VCEP guidelines the rule for PP3 is: "Supporting for missense variants with REVEL ≥0.7 or splicing predictions matching disease mechanism." The evidence for this variant shows: it is synonymous and splicing predictors show no impact. Therefore, this criterion is not applied.
PP4 (Not Applied)
According to standard ACMG guidelines the rule for PP4 is: "Supporting when patient phenotype is highly specific for a single gene disorder." The evidence for this variant shows: no patient phenotype data provided. Therefore, this criterion is not applied.
PP5 (Not Applied)
According to standard ACMG guidelines the rule for PP5 is: "Supporting when a reputable source reports the variant as pathogenic without primary evidence." The evidence for this variant shows: ClinVar entries are conflicting (Likely benign and VUS). Therefore, this criterion is not applied.
BA1 (Not Applied)
According to VCEP guidelines the rule for BA1 is: "Stand Alone if gnomAD filtering allele frequency ≥0.05%." The evidence for this variant shows: MAF = 0.0018%, below threshold. Therefore, this criterion is not applied.
BS1 (Not Applied)
According to VCEP guidelines the rule for BS1 is: "Strong if gnomAD filtering allele frequency ≥0.025%." The evidence for this variant shows: MAF = 0.0018%, below threshold. Therefore, this criterion is not applied.
BS2 (Not Applied)
According to standard ACMG guidelines the rule for BS2 is: "Strong/Supporting when observed in healthy adult individuals for disorders with full penetrance." The evidence for this variant shows: no observations in well‐characterized healthy cohorts. Therefore, this criterion is not applied.
BS3 (Not Applied)
According to standard ACMG guidelines the rule for BS3 is: "Strong when well‐established functional studies show no damaging effect." The evidence for this variant shows: no functional study data. Therefore, this criterion is not applied.
BS4 (Not Applied)
According to standard ACMG guidelines the rule for BS4 is: "Strong when lack of segregation in affected members of a family." The evidence for this variant shows: segregation data unavailable. Therefore, this criterion is not applied.
BP1 (Not Applied)
According to VCEP guidelines the rule for BP1 is: "Supporting for truncating variants in genes where gain-of-function is disease mechanism." The evidence for this variant shows: it is synonymous, not truncating. Therefore, this criterion is not applied.
BP2 (Not Applied)
According to standard ACMG guidelines the rule for BP2 is: "Supports benign when observed in trans with a pathogenic variant for a dominant disorder or cis with another pathogenic variant for recessive." 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: "Supporting when in-frame indels in repetitive regions without known function." The evidence for this variant shows: it is synonymous, not an indel. Therefore, this criterion is not applied.
BP4 (Not Applied)
According to VCEP guidelines the rule for BP4 is: "Supporting for missense variants with REVEL ≤0.3." The evidence for this variant shows: it is synonymous, not missense, despite benign computational predictions. Therefore, this criterion is not applied.
BP5 (Not Applied)
According to standard ACMG guidelines the rule for BP5 is: "Supporting when a variant is found in a case with an alternate molecular basis for disease." The evidence for this variant shows: no such cases reported. Therefore, this criterion is not applied.
BP6 (Not Applied)
According to standard ACMG guidelines the rule for BP6 is: "Supporting when a reputable source reports the variant as benign without evidence." The evidence for this variant shows: ClinVar submissions include Likely benign but with conflicting calls. Therefore, this criterion is not applied.
BP7 (Supporting)
According to VCEP guidelines the rule for BP7 is: "Supporting A synonymous (silent) variant for which splicing prediction algorithms predict no impact to the splice consensus sequence nor the creation of a new splice site AND the nucleotide is not highly conserved." The evidence for this variant shows: it is synonymous (E31=), SpliceAI predicts no impact on splicing, and the nucleotide is not highly conserved. Therefore, this criterion is applied at Supporting strength.
