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.

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.14508042).

Collection Method: clinical testing

The c.6848A>G (p.Q2283R) alteration is located in exon 43 (coding exon 43) of the ROS1 gene. This alteration results from a A to G substitution at nucleotide position 6848, causing the glutamine (Q) at amino acid position 2283 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
