Classification rationale
1

The PALB2 NM_024675.4:c.194C>T (NP_078951.2:p.(Pro65Leu), p.(P65L)) variant has been reported in ClinVar, but no expert panel classification is available.

This variant is present in gnomAD v4.1 at 0.00577% (93/1612258 alleles) with a highest observed population frequency of 0.00961%, which is below the PALB2 BS1 threshold of 0.01% and above the PM2_Supporting threshold of 0.000333%.

SpliceAI predicts no significant splice impact (max delta score 0.00), and missense predictor scores are low (REVEL 0.029; BayesDel -0.55193), although the PALB2 expert specification does not use missense computational predictors for PP3 or BP4 in this setting.

OncoKB: Unknown Oncogenic Effect
OncoKB did not identify variant-specific reviewed functional evidence for this variant; gene-level curated context is available for reviewer follow-up. PALB2, a scaffolding protein involved in DNA repair, is altered in various cancers.
