The NRAS Pyro Kit is used for quantitative measurements of mutations in codons 12, 13, and 61 of the human NRAS gene in real time using Pyrosequencing technology on the PyroMark Q24 System. The NRAS gene encodes a GTPase neuroblastoma RAS viral (v-ras) oncogene homolog. Mutations in NRAS are found in approximately 13–25% of all malignant melanomas, occurring frequently in codons 12, 13, and 61. These mutations results in the constitutive activation of NRAS signaling pathways.
The following mutations are detected:
- Codon 12/13: G12A, G12C, G12D, G12R, G12S, G12V, G13A, G13C, G13D, G13R, G13S, G13V
- Codon 61: Q61E, Q61H, Q61K, Q61L, Q61P, Q61R
