Genes affected
DDR2 (HGNC:2731): (discoidin domain receptor tyrosine kinase 2) This gene encodes a member of the discoidin domain receptor subclass of the receptor tyrosine kinase (RTKs) protein family. RTKs play a key role in the communication of cells with their microenvironment. The encoded protein is a collagen-induced receptor that activates signal transduction pathways involved in cell adhesion, proliferation, and extracellular matrix remodeling. This protein is expressed in numerous cell types and may alos be involved in wound repair and regulate tumor growth and invasiveness. Mutations in this gene are the cause of short limb-hand type spondylometaepiphyseal dysplasia. [provided by RefSeq, Aug 2017]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

PP2
Missense variant in the DDR2 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 12 curated pathogenic missense variants (we use a threshold of 10). The gene has 3 curated benign missense variants. Gene score misZ: 2.2869 (below the threshold of 3.09). Trascript score misZ: 3.8204 (above the threshold of 3.09). GenCC associations: The gene is linked to warburg-cinotti syndrome, spondyloepimetaphyseal dysplasia-short limb-abnormal calcification syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.36534408).
