Genes affected
ROS1 (HGNC:10261): (ROS proto-oncogene 1, receptor tyrosine kinase) This proto-oncogene, highly-expressed in a variety of tumor cell lines, belongs to the sevenless subfamily of tyrosine kinase insulin receptor genes. The protein encoded by this gene is a type I integral membrane protein with tyrosine kinase activity. The protein may function as a growth or differentiation factor receptor.

The c.6659A>T (p.N2220I) alteration is located in exon 42 (coding exon 42) of the ROS1 gene. This alteration results from a A to T substitution at nucleotide position 6659, causing the asparagine (N) at amino acid position 2220 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
