The recorded framework is ClinGen PMS2 VCEP v2.0.0. The criteria and strengths shown below come from the saved assessment; this page does not recalculate the classification.
The applied criteria and their strengths are shown as assessed under the stated framework.
No pathogenic criterion marked as applied in the recorded assessment.
VCEP BS1 requires gnomAD v4 grpmax filtering allele frequency ≥ 0.00028 and < 0.0028 (0.028–0.28%). This variant has gnomAD v4.1 grpmax FAF = 0.00062731 (0.0627%), which falls within the BS1 range. The variant is also observed with 5 homozygotes in gnomAD v4.1 and 2 homozygotes in gnomAD v2.1, providing additional evidence against a highly penetrant pathogenic role. The variant is not a recognized founder pathogenic variant.
SpliceAI predicts no splicing impact (max delta = 0.00) for this synonymous variant, consistent with normal mRNA processing. The PMS2 VCEP has classified this variant as Benign citing BS3 evidence. The VCEP BS3 rule for synonymous variants requires laboratory assays with NMD inhibition showing no mRNA aberration; the SpliceAI prediction of delta=0.00 provides computational support, though direct review of functional assay data (PMID:25985013, PMID:30998989) is recommended for upgrade to BS3_Strong.
VCEP BP4 rule for intronic and synonymous variants: SpliceAI predicts no splicing impact with delta score ≤ 0.1. This variant has SpliceAI max delta = 0.00, meeting the BP4_Supporting threshold. REVEL and BayesDel scores are not available for this synonymous variant, as expected.
Synonymous variant (p.Ile755=) at c.2265 in exon 13 of PMS2 (c.2175–2275). The variant lies at position -10 from the donor splice site, which is within the VCEP BP7 region (at or beyond -21 from the donor). SpliceAI delta = 0.00 confirms no predicted splicing impact. The ClinGen PMS2 VCEP classified this variant as Benign and applied BP7. Per VCEP rules, variants may satisfy both BP7 and BP4.
ClinGen InSiGHT Hereditary Colorectal Cancer/Polyposis Expert Panel Specifications to the ACMG/AMP Variant Interpretation Guidelines for PMS2 Version 2.0.0 v2.0.0 criteria-combination framework: matched Rule19 (Benign.Supporting >=2) with applied criteria: BS1 strong, BS3 supporting, BP4 supporting, BP7 supporting; maps to Likely Benign.

NM_000535.7:c.2265C>T is a synonymous variant in PMS2 (p.Ile755=) with SpliceAI delta score of 0.00, predicting no splicing impact.
This variant is present in gnomAD v4.1 at an allele frequency of 5.74e-05 (92/1,602,058 alleles) with 5 homozygotes, and gnomAD v2.1 at 8.82e-05 (22/249,348 alleles) with 2 homozygotes. The gnomAD v4.1 grpmax filtering allele frequency is 0.00062731 (0.0627%), meeting the PMS2 VCEP BS1 threshold (≥0.028%, <0.28%) at Strong strength.
SpliceAI predicts no splicing impact (max delta = 0.00), satisfying the VCEP BP4_Supporting criterion for synonymous variants (delta ≤ 0.1).
As a synonymous variant located within the splice region at position c.2265 (exon 13, donor -10) with no predicted splicing impact, the VCEP BP7_Supporting criterion is met.
The PMS2 VCEP has classified this variant as Benign (ClinGen InSiGHT Hereditary Colorectal Cancer/Polyposis Expert Panel Specifications v2.0.0). Nine clinical laboratories in ClinVar report this variant as Likely benign (5) or Benign (4).
Applying the PMS2 VCEP v2.0.0 ACMG/AMP combination rules: BS1 (Strong) + BP4 (Supporting) + BP7 (Supporting) yields a classification of Likely Benign per Rule 18 (1 Benign Strong + 1 Benign Supporting → Likely Benign). The variant is classified as Likely Benign.
