In a screening-enriched cohort of 228 Mexican patients with breast and/or ovarian cancer from Jalisco, BRCA1 variants were detected in 14.0%, with carrier proportions of 16.2% in ovarian and 13.6% in breast cancer. Variant functional effects were predicted using Ensembl VEP, SIFT, PolyPhen-2, REVEL, CADD, and AlphaMissense, and splicing consequences were assessed with SpliceAI.

Breast and ovarian cancer are among the most common neoplasms in women, and germline variants in the BRCA1 gene markedly increase the risk of developing them. Despite existing studies, the frequency and spectrum of BRCA1 variants in women from Jalisco, Mexico, remain underexplored. Objective. To identify and characterize BRCA1 variants in a cohort of Mexican women with breast and ovarian cancer, and to assess their functional and splicing consequences through computational analysis. Methodology. Genomic DNA from 228 women with breast and/or ovarian cancer, selected by clinical criteria suggestive of hereditary cancer, was analyzed by next-generation sequencing. The functional impact of point variants was predicted with Ensembl VEP, SIFT, PolyPhen- 2, REVEL, CADD, and AlphaMissense, and their effect on splicing was evaluated with SpliceAI, using the MANE Select canonical transcript (NM_ 007294.4) . Results. BRCA1 variants were identified in 14","cbCaiprcUMzKVyA3","https://ap.wps.com/l/cbCaiprcUMzKVyA3","pdf",1349458,16,"English","# Abstract\n## Background\n## Objective\n## Methodology\n## Results\n## Conclusions\n# Introduction","[{\"question\":\"What is the objective of the BRCA1 study in women from Jalisco, Mexico?\",\"answer\":\"The study aims to identify and characterize BRCA1 variants in a cohort of Mexican women with breast and ovarian cancer and to assess functional and splicing consequences using computational analysis.\"},{\"question\":\"How were BRCA1 variants detected and analyzed in this cohort?\",\"answer\":\"Genomic DNA from 228 women was analyzed by next-generation sequencing.
