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 made for transcript

Verdict is Benign. Variant got -19 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=0.003576517).

BP6

Variant 1-162772032-G-A is Benign according to our data. Variant chr1-162772032-G-A is described in ClinVar as [Benign]. Clinvar id is 282994.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00265 (403/152274) while in subpopulation AFR AF= 0.0091 (378/41546). AF 95% confidence interval is 0.00834. There are 2 homozygotes in gnomad4. There are 210 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.

BS2

High AC in GnomAd4 at 403 AD gene.
