Human KRAS Gene Mutation Detection Assays

Product Description

The assays (primers and probes only) are designed to detect the KRAS (V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog) mutations in tissue DNA and cfDNA from plasma. 

The K-ras gene (K-ras, p21) family consists of three genes associated with human tumors: H-ras, K-ras, and N-ras, located on chromosomes 11, 12, and 1, respectively. The K-ras gene, also known as the p21 gene, encodes a 21kD Ras protein. Among the Ras genes, K-Ras has the greatest impact on human cancers and functions as a molecular switch. In its normal state, it controls the pathway regulating cell growth. However, when it is mutated, it causes continuous cell growth and inhibits self-destruction. K-ras also plays a role in intracellular signal transmission. Mutations in the K-ras gene result in its permanent activation, preventing the production of normal Ras protein, which leads to disrupted intracellular signaling, uncontrolled cell proliferation, and the development of cancer.

Approximately 30% of human malignant tumors are associated with Ras gene mutations, and mutated Ras proteins are often in an active state. K-ras mutations are commonly found in leukemia, lung cancer, rectal cancer, and pancreatic cancer, with mutations occurring in 30%-35% of rectal cancers. Around 96% of KRAS gene mutations occur at codons 12 and 13 of exon 2, and KRAS G12D mutations account for approximately 17-18%.
