We used CRISPR/Cas9-mediated genome editing in FVB mouse zygotes to model the BRCA1 coiled-coil domain VUS c.4220T>C p.L1407P, which disrupts the interaction of BRCA1 with PALB2. The BRCA1 coiled-coil domain is well cons
[Paragraph-level] PMCID: PMC7612117 Section: RESULTS PassageIndex: 3
Evidence Type(s): Functional, Oncogenic
Justification: Functional: The passage discusses how the variant p.L1407P disrupts the interaction of BRCA1 with PALB2 and predicts that it disables the alpha-helical structure of the coiled-coil domain, indicating an alteration in molecular function. Oncogenic: The use of CRISPR/Cas9 to model the BRCA1 variant in mice suggests that the variant contributes to tumor development or progression, as it is being studied in the context of a gene essential for embryonic development and cancer biology.
