SNP analysis and identification may help predict an individual’s response to certain drugs, susceptibility to environmental factors, and risk for developing diseases. Alternatively, SNPs can be used to track inheritance of disease genes within families and provide insight into SNP linkage.
Sanger sequencing-based SNP genotyping can be performed on a small subset of samples or as part of large-scale projects. Whether you are using genotyping as your primary approach for SNP analysis and detection, or to confirm next generation sequencing and microarray results, GENEWIZ can help accelerate your project. Let the Sanger sequencing experts at GENEWIZ support your SNP genotyping research objectives with speed, quality, and reliability.

Example: BRAF c.1799T>A (V600E) Mutation in Melanoma
Mutations in BRAF are largely linked to malignant melanomas. Mutations at BRAF V600 are common indicators for responsiveness to treatment for melanoma patients.
