Identification of Genetic Predisposition to Early Breast Cancer in Kazakh Women
Researchers conducted a study in Kazakhstan to determine the genetic factors that predispose Kazakh women to develop early onset breast cancer. They enrolled 224 unrelated Kazakh women diagnosed with early onset breast cancer and analyzed their germline mutations and gene expression profiles using next-generation sequencing technology. The study revealed 38 pathogenic variants in 13 different genes, including recurrent variants in BRCA1 and BRCA2, suggesting possible founder mutations in the Kazakh population. The findings demonstrate the efficacy of next-generation sequencing to identify rare germline variants and emphasize the importance of studying diverse ethnic groups in breast cancer research.
