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.
This variant is rare in population databases and meets the TP53 VCEP PM2 threshold. In gnomAD v4.1, the total allele frequency is 4.95699e-06, which is below the PM2 cutoff of 0.00003, and the joint grpmax filtering allele frequency is 4.43e-06. In gnomAD v2.1, the total allele frequency is 7.07234e-06, also below the threshold.
Published TP53 functional evidence supports a benign effect. In the TP53 VCEP functional worksheet, p.Arg379His is classified as functional in the Kato assay set and as no loss of function in the Giacomelli assay set, with a pre-assigned BS3 code.
Computational evidence supports a benign effect under the TP53 VCEP missense rules. The TP53 VCEP bioinformatic worksheet assigns BP4_moderate for c.1136G>A with Align-GVGD class C0 and BayesDel -0.0720003, which is below the BP4_moderate cutoff of -0.008, and there is no predicted splice impact (worksheet SpliceAI 0.08; case SpliceAI max delta score 0.00, both below 0.2). REVEL is available at 0.338 and does not contradict the benign VCEP bioinformatic assignment.
Expert panel ClinGen TP53 Variant Curation Expert Panel, ClinGen classified as Likely benign.
Tavtigian et.al., 2020 - Bayesian adaptation of Richards et.al., 2015 v2.4.0 point-based framework: BS3 strong (-4) + BP4 moderate (-2) + PM2 supporting (+1) + BP6 supporting benign (-1) = -6 points, which maps to Likely Benign.

The TP53 c.1136G>A (p.Arg379His) variant has been reported in ClinVar, including a Likely Benign expert-panel assertion from the ClinGen TP53 Variant Curation Expert Panel.
This variant is rare in population databases, with a gnomAD v4.1 total allele frequency of 4.95699e-06 and joint grpmax filtering allele frequency of 4.43e-06, which supports PM2_Supporting and is below the BS1 and BA1 thresholds.
In published TP53 functional studies summarized by the TP53 VCEP functional worksheet, p.Arg379His was functional in the Kato assay set and showed no loss of function in the Giacomelli assay set, supporting BS3 and arguing against PS3.
TP53 VCEP in silico assessment supports a benign computational effect: the variant is assigned BP4_moderate in the TP53 bioinformatic worksheet, BayesDel is -0.0720003, SpliceAI shows no significant splice effect, and REVEL is 0.338.
No criteria match.
PM2 Supporting applies for AF <0.00003 in gnomAD or another large sequenced population.
BS3 Strong for TP53 requires functional evidence showing no loss of function under the VCEP framework.
BP4 Moderate for TP53 missense variants requires BayesDel <= -0.008 and no predicted splicing effect (SpliceAI <0.2).
TP53 VCEP PS3 requires non-functional or loss-of-function assay evidence.
PM1 applies to codons 175, 245, 248, 249, 273, 282 or qualifying Cancer Hotspots recurrence.
TP53 VCEP PP3 missense thresholds are not met for this variant.
BA1 requires FAF >=0.001 in an eligible gnomAD ancestry group.
