About PTEN

No gene-level summary was recorded for this case.

LYFE Sciences is an AI system, and it can make mistakes. Criteria may be applied incorrectly, sources may be misread, and a confident-looking classification can still be wrong. Double-check every criterion and its underlying evidence before relying on any call.

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.
