Classification rationale
1

The PALB2 c.2524_2535delinsTCAGA (p.(Ala842SerfsTer7)) variant has not been observed in somatic cancers in COSMIC and has been reported in ClinVar as pathogenic, including an expert-panel pathogenic classification.

2

This variant is absent from gnomAD v2.1 and gnomAD v4.1, placing it below the PALB2 PM2_Supporting population threshold of 0.000333%.

3

The predicted consequence is a frameshift with premature termination, p.(Ala842SerfsTer7), in a gene where loss of function is an established disease mechanism, supporting truncating-variant evidence under the PALB2 specification.

cspec ↗
4

SpliceAI predicts no significant splice effect for this variant, with a maximum delta score of 0.10, supporting interpretation of the variant as a truncating allele rather than a splice-altering event.
