Discussion

Saturation genome editing identifies 538 function-altering BRCA1 variants in HAP1 and HMECs, suggesting varying cancer risk implications.

Nearly half of BRCA1 variants identified as impacting function in HAP1 cells were neutral in HMECs, indicating context-dependent effects and risks.
A total of 4,113 single-nucleotide variants were scored through saturation genome editing, highlighting the importance of cellular context in variant analysis.
Function scores from this approach discriminate known pathogenic from benign variants with near-perfect accuracy, aiming to improve clinical interpretations.
This research underscores the need for a broader understanding of variant effects across different cell types to address cancer risks more accurately.

Dace et al. (2025) studied this question.
