Cancer gene mutation discovery and detection using array-based resequencing
Breast Cancer Research volume 7, Article number: P4.51 (2005)
We set out to determine the feasibility of using microarray-based resequencing for cancer gene mutation screening by designing GeneChip CustomSeq Resequencing arrays (Affymetrix, Santa Clara, CA, USA) for interrogation of ARAF, BRAF, CDK4, CDK6, CDKN2A, KLF6, HRAS, KRAS, MET, NRAS, PTEN, RAF1, RB1, RET and TP53 (164 exons in total). Arrays also included four intronic bases on either side of the exons to cover splice sites, thus the arrays covered a total of 23,966 bases. Overall performance was very good, with accuracy >99.99% and coverage ~97.5%. Twenty NSCLC samples were analyzed using the arrays, and several well-characterized somatic mutations and germline variants were found. The most significant novel finding was the detection of a transforming MET mutation (T1010I) in a NSCLC patient.
