    Characterization of PIK3CA/AKT1/PTEN gene mutations in hormone receptor- positive/HER2-negative breast cancer (PubMed, Zhonghua Bing Li Xue Za Zhi)
    For AKT1 gene mutation, only E17K was observed.Mutations of PIK3CA/AKT1/PTEN genes are more likely to occur over 40 year-old patients.In this cohort, the PIK3CA V346G mutation (co-existent PIK3CA H1047L) and the PTEN V343fs mutation were not found in previous publications. In addition to the predominance of common loci, PIK3CA and PTEN gene mutations also have rare loci mutations in the breast cancer, warranting further analysis with an expanded sample size.
