The PALB2 c.532del (p.(Glu178AsnfsTer15), p.(E178Nfs*15)) variant has not been observed in COSMIC and has been reported in ClinVar as Pathogenic, including expert panel review.
clinvar ↗This variant is absent from gnomAD v4.1 and gnomAD v2.1, placing its observed population frequency at 0%, which is below the PALB2 PM2_Supporting threshold of 0.000333% and below the BS1 and BA1 benign frequency thresholds.
gnomad_v4 ↗ gnomad_v2 ↗ cspec ↗This variant is a frameshift predicted to generate an early truncating protein product, and PALB2 loss of function is an established disease mechanism in the applicable VCEP framework, supporting a loss-of-function interpretation.
cspec ↗SpliceAI predicts no significant splice impact, with a maximum delta score of 0.05, which is below the PALB2 PP3 threshold of 0.2 and below the BP4 splice threshold of 0.1.
