NF1 germline mutation in a Chinese family with colon cancer

Colorectal cancer (CRC) is a leading cause of cancer death worldwide. Recent advances in genomic medicine have identified novel gene mutations that contribute to an increased risk of CRC. Here, we describe a diagnosis of colon cancer in a 63-year-old woman and also in her brother. Next-generation se...

Sumario:Colorectal cancer (CRC) is a leading cause of cancer death worldwide. Recent advances in genomic medicine have identified novel gene mutations that contribute to an increased risk of CRC. Here, we describe a diagnosis of colon cancer in a 63-year-old woman and also in her brother. Next-generation sequencing showed that both patients harbored a germline mutation in NF1. The female patient also carried co-mutations in KRAS and NRAS. Furthermore, the NF1 germline mutation was identified in a healthy offspring of the brother. The female patient received three cycles of bevacizumab plus capecitabine/oxaliplatin therapy and achieved stable disease of the primary lesion in the colon and partial response of metastasis in the right abdominal cavity. This study highlights the association of NF1 germline mutations with colon cancer.
