The recorded framework is ClinGen TP53 VCEP v2.4.0. 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.
The variant is absent from gnomAD v2.1, gnomAD v4.1, and gnomAD-Canada v1.0, meeting the TP53 VCEP PM2_Supporting threshold of allele frequency <0.00003 (0.003%).
The TP53 VCEP Functional-worksheet pre-assigns BS3 (strong benign functional evidence) for p.Asp228Glu. The variant is Functional in the Kato et al. (PMID:12826609) systematic assay and shows no loss of function (noLOF) across all eligible assays: Giacomelli et al. (PMID:30224644), Kotler et al. (PMID:29979965), and Kawaguchi et al. This meets the VCEP BS3 rule: 'Functional on Kato et al. data AND no loss of function (LOF) by the majority of available eligible assays.'
The variant has a BayesDel score of -0.133538, which is ≤ -0.008, and SpliceAI predicts no splicing impact (max delta = 0.00, which is <0.2). The aGVGD class is C0 (not C65). Per the TP53 VCEP PP3-BP4 missense flowchart: BayesDel ≤ -0.008 + no predicted splicing differences + not C65 = BP4_Moderate. The VCEP PP3-BP4-codes spreadsheet confirms this with a pre-assigned code of BP4_moderate.
Total points: PM2_Supporting (+1) + BS3 (-4) + BP4_Moderate (-2) = -5. Per the TP53 VCEP v2.4.0 Tavtigian Bayesian point-based framework, a score of -5 falls in the Likely Benign range (Rule4: -6 to -2).

NM_000546.5:c.684C>G (p.Asp228Glu) is a missense variant in exon 7 of TP53.
The variant is absent from gnomAD v2.1, v4.1, and gnomAD-Canada (PM2_Supporting; +1 point).
Functional evidence from the TP53 VCEP Functional-worksheet demonstrates the variant retains wild-type-like function: Kato et al. assay shows Functional activity, and all eligible assays (Giacomelli, Kotler, Kawaguchi) report no loss of function (BS3; -4 points).
In silico evidence supports a benign interpretation: BayesDel score is -0.133538 (Class C0), and SpliceAI predicts no splicing impact (max delta 0.00). The VCEP PP3-BP4-codes spreadsheet assigns BP4_moderate (-2 points).
Codon 228 is not among the VCEP-defined hotspot codons (175, 245, 248, 249, 273, 282), and the variant is not listed in cancerhotspots.org; PM1 is not met.
PP3 is not met per VCEP in silico flowchart: BayesDel score does not meet the ≥0.16 threshold and aGVGD class is C0.
PS3 is not met: the functional evidence favors a benign interpretation; the VCEP pre-assigned code is BS3, not PS3.
Total points: PM2_Supporting (+1) + BS3 (-4) + BP4_Moderate (-2) = -5. Per the Tavtigian Bayesian point-based framework (TP53 VCEP v2.4.0), a score of -5 falls in the Likely Benign range (-6 to -2).
This variant has been reported in ClinVar as Uncertain significance by 5 clinical laboratories and as Likely benign by 1 clinical laboratory (ClinVar ID: 926556).
COSMIC reports 6 somatic occurrences (COSV52662428). OncoKB classifies the variant as Likely Oncogenic with likely loss-of-function effect, which is inconsistent with the VCEP functional data showing retained function; the VCEP functional worksheet takes precedence for germline classification.
No de novo, segregation, proband, or case-control data are available; PS2, PS4, PP1, PP4, BS2, and BS4 remain unassessed.
