Recently, Pao and Ladanyi [5] compared 13 methods for detecting the common 15 bp epidermal growth factor receptor (EGFR) deletion in lung cancers (including Loop-hybrid mobility shift assay, Cycleave PCR, PCR-RFLP and length analysis, MALDI-TOF MS–based genotyping, PNA-LNA PCR clamp, Scorptions ARMS, Mutant-enriched PCR). Here, EGFR is linked to lung carcinoma.
