Classification rationale
1

The BRCA1 c.2063del (p.Thr688LysfsTer13; p.T688Kfs*13) variant has not been observed in COSMIC and has not been reported in ClinVar.

2

This variant is absent from gnomAD v2.1 and gnomAD v4.1, supporting rarity in population controls.

3

This frameshift deletion occurs in BRCA1 exon 10 (legacy exon 11) and is predicted to introduce a premature termination codon; under the ENIGMA BRCA1 specification, truncating variants in this exon meet PVS1 and the exon also carries PM5_Strong (PTC).

SpliceAI predicts no significant additional splice impact for this deletion, with a maximum delta score of 0.00.
