The recorded framework is ClinGen PTEN VCEP v3.2. 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 present at extremely low frequency in population databases, meeting the PTEN VCEP PM2_Supporting threshold. In gnomAD v4.1, it is observed in 1 of 1,585,530 alleles (AF=6.3×10⁻⁷; 0.000063%), which is well below the VCEP threshold of <0.001% (0.00001). The highest subpopulation frequency is in European (non-Finnish) at 1/1,168,048 alleles (AF=8.6×10⁻⁷; 0.000086%), also below the 0.002% subpopulation threshold. Absent from gnomAD v2.1 and gnomAD-Canada.

NM_000314.8:c.802-3T>A is an intronic variant at position -3 of the acceptor splice site of PTEN intron 7. It is present at extremely low frequency in gnomAD v4.1 (1/1,585,530 alleles, AF=6.3×10⁻⁷).
This variant has been classified as Likely Benign by the ClinGen PTEN Variant Curation Expert Panel (ClinVar ID 135912, 3-star expert panel review).
SpliceAI predicts no significant splicing impact (max delta score = 0.07). Computational tools collectively predict no effect on normal splicing, as noted in one clinical laboratory submission.
The variant is absent from gnomAD v2.1 and observed only once in gnomAD v4.1, meeting PTEN VCEP PM2_Supporting due to extremely low population frequency.
BP6 is applied at supporting benign level based on the ClinGen PTEN EP classification of Likely Benign (3-star expert panel review).
No functional splicing assay, de novo, segregation, or case-control data is available for this variant. The overall evidence profile supports a likely benign interpretation consistent with the expert panel classification.
