Additionally, targeted sequencing of the kinase domain of FGFR1 in 52 NSCLC cell lines and of the entire FGFR1 coding sequence in three cell lines (NCI-H1581, NCI-H1703, NCI-H2170) did not reveal any evidence of kinase domain mutations (data not shown). Here, FGFR1 is linked to non-small cell lung carcinoma.
