Mutations of K-ras gene have been proven to play important roles in human tumor progression. Point mutations of K-ras gene located in codons 61 are gene hot spot mutation regions in patients with gastric cancer. A simple and effective capillary electrophoresis (CE) method for point mutation detection in codon 61 of K-ras gene was established. The polymerase chain reaction (PCR) fragments included codon 61 of K-ras gene were analyzed by single-strand conformation polymorphism (SSCP)-CE method. The CE analysis was performed by using a 1×Tris–borate–EDTA (TBE) buffer containing 3.0% (w/v) poly (ethylene oxide) (PEO) (MW 300 000) under reverse polarity with 15 oC and voltage of 15 kV. Forty-two gastric cancer patients were analyzed using this developed method. K-ras gene mutation was found in 17 cases (40.5 %) and the results showed that K-ras gene mutation in gastric cancer tissue is a usual event, and the SSCP-CE was feasible for mutation detection of K-ras gene in populations. Detection of gene mutation of gastric cancer tissue by PCR - SSCP has a certain value to diagnosis of gastric cancer and to prevent gastric cancer associated with clinical and pathological features, living habits of different patients by detection mutation of K-ras gene codon 61.

With the rapid decline cost of sequencing, it is now clinically affordable to examine multiple genes in a single disease-targeted test using next generation sequencing. Current targeted sequencing methods require a separate step of targeted capture enrichment during sample preparation before sequencing, and the library preparation process is labor intensive and time consuming. Here, we introduced an amplification-free Single Molecule Targeted Sequencing (SMTS) technology, which combined targeted capture and sequencing in one step. We demonstrated that this technology can detect low-frequency mutations of cancer genes. SMTS has several advantages, namely that it requires little sample preparation and avoids biases and errors introduced by PCR reaction. This technology can be applied in cancer gene mutation detection, inherited condition screening and high-resolution human leukocyte antigen (HLA) typing.
