Kind: research · Impact: medium

## In brief

- A Nature Genetics paper published online 11 November 2026 reports saturation genome editing of BRCA1 across two cell models.
- The study maps the functional effects of thousands of BRCA1 variants.
- Variants scored discordantly between the two cell types reflect the importance of cellular context for interpreting variant effects.

## Why it matters

Better functional maps of BRCA1 variants can help classify variants of uncertain significance, which matters for clinical interpretation of hereditary breast and ovarian cancer risk.
