About PTPN11

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.

The PTPN11 NM_001330437.1:c.526-8C>A (NP_001317366.1:p.?) variant has been reported in ClinVar and is classified as Benign by the ClinGen RASopathy Variant Curation Expert Panel.

This variant is present in gnomAD v2.1 at 0.06730% and in gnomAD v4.1 at 0.13022%, which are both above the PTPN11 BA1 threshold of 0.05% and the BS1 threshold of 0.025%.

SpliceAI predicts no significant splice impact, with a maximum delta score of 0.06, which supports BP4 and does not support PP3 for a splice-region effect.
