Identifying germline mutations associated with cancer risk and predisposition

Analyze germline mutations that predispose individuals to cancer using next-generation sequencing and microarrays

Germline Mutation Detection in Cancer

Germline mutations, also called hereditary mutations, are passed on from parents to offspring. Inherited germline mutations play an important role in cancer risk and susceptibility. Knowledge of these hereditary mutations can lead to the development of preventive measures to reduce the likelihood of developing cancer.

Inherited mutations associated with hereditary cancer risk can be analyzed through various approaches, including next-generation sequencing (NGS) and microarrays.

Oncology

NGS methods enable researchers to rapidly sequence known or suspected hereditary cancer risk-related genes. NGS can detect large numbers of germline mutations at once and/or identify novel germline variants linked to cancer.

Whole-genome sequencing provides a comprehensive picture of germline mutations across the entire cancer genome. Targeted sequencing studies use hereditary cancer panels to assess only the genes that have known associations with cancer predisposition, reducing sequencing costs and data analysis burdens.

Germline Mutation Linked to Familial Melanoma

Researchers used high-throughput sequencing to identify a germline mutation in the promoter of the telomerase reverse transcriptase gene.

Microarrays offer an economical method for studying germline mutations in cancer. With arrays, hundreds of thousands of known single nucleotide polymorphisms (SNPs) can be studied across large sample sets simultaneously.

These studies can provide insight into genetic risk factors linked to cancer as well as genotypes associated with drug response.
