The mode of inheritance of this gene has been updated to 'BOTH monoallelic and biallelic, autosomal or pseudoautosomal' following NHS Genomic Medicine Service approval.Created: 30 Jan 2023, 5:34 p.m. | Last Modified: 30 Jan 2023, 5:34 p.m.
Panel Version: 1.2
Comment on mode of inheritance: Although more rare, biallelic germline BRCA1 variants have been shown to also confer breast and ovarian cancer susceptibility (with or without FA‐like features), and multiple such cases have been reported worldwide (PMIDs: 23269703; 25472942; 31347298; 33477375).
This may warrant an MOI change from 'monoallelic' to 'both mono- and biallelic' to ensure these rarer cases are not missed; however this will be flagged for further review to confirm whether the GMS expert group agrees with the change.Created: 4 Apr 2022, 11:13 a.m. | Last Modified: 4 Apr 2022, 11:13 a.m.
