DDR2 (discoidin domain receptor tyrosine kinase 2) is a gene that encodes the discoidin domain-containing receptor 2 protein, a tyrosine kinase. Binding of collagen to DDR2 results in activation of downstream signaling pathways, perhaps the SRC and STAT signaling pathways. Similar to integrin receptors, DDR2 may play a role in modulating cellular interactions with the extracellular matrix.

 

DDR2 is altered in 2.00% of all cancers with lung adenocarcinoma, breast invasive ductal carcinoma, colon adenocarcinoma, endometrial endometrioid adenocarcinoma, and bladder urothelial carcinoma having the greatest prevalence of alterations [3].

The most common alterations in DDR2 are DDR2 Mutation (1.48%), DDR2 Amplification (0.52%), DDR2 R668H (0.03%), DDR2 R752H (0.03%), and DDR2 R105C (0.02%) [3].
