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.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.7021G>A (p.G2341R) alteration is located in exon 43 (coding exon 43) of the ROS1 gene. This alteration results from a G to A substitution at nucleotide position 7021, causing the glycine (G) at amino acid position 2341 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
