Genes affected

DDR1 (HGNC:2730): (discoidin domain receptor tyrosine kinase 1) Receptor tyrosine kinases play a key role in the communication of cells with their microenvironment. These kinases are involved in the regulation of cell growth, differentiation and metabolism. The protein encoded by this gene belongs to a subfamily of tyrosine kinase receptors with homology to Dictyostelium discoideum protein discoidin I in their extracellular domain, and that are activated by various types of collagen. Expression of this protein is restricted to epithelial cells, particularly in the kidney, lung, gastrointestinal tract, and brain. In addition, it has been shown to be significantly overexpressed in several human tumors. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.

The c.1045C>T (p.R349C) alteration is located in exon 7 (coding exon 7) of the DDR1 gene. This alteration results from a C to T substitution at nucleotide position 1045, causing the arginine (R) at amino acid position 349 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
