Arthrogryposis v9.30 DDR2 Ida Ertmanska gene: DDR2 was added
gene: DDR2 was added to Arthrogryposis. Sources: Literature
Q1_26_promote_green tags were added to gene: DDR2.
Mode of inheritance for gene: DDR2 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Publications for gene: DDR2 were set to 30449416
Review for gene: DDR2 was set to GREEN
Added comment: 30449416 Xu et al,, 2018
6 patients from 4 unrelated families, 2 previously reported. All patients were heterozygous for one of the recurring DDR2 variants: c.1829T>C (p.Leu610Pro) or c.2219A>G (p.Tyr740Cys).
Phenotypic spectrum: contractures (6/6, variable severity), corneal vascularization (5/6), skin with little subcutaneous tissue (4/6), keloid-like plaques (4/6), loss of toes/toenails (4/6), joint swellings (4/6), and other less penetrant features.

This gene is associated with AD Warburg-Cinotti syndrome 618175 and AR Spondylometaepiphyseal dysplasia, short limb-hand type 271665 (OMIM accessed 13th Mar 2026).

Arthrogryposis v5.10 FILIP1 Achchuthan Shanmugasundram changed review comment from: PMID:36344539 reported a single male with biallelic variant in FILIP1 (c.2665C > T/ p.Arg889Ter) gene and presenting with distal arthrogryposis with contractures of the knees and elbows, congenital clubfoot, muscular hypotonia, and mild learning disability.

PMID:36943452 reported five individuals from three unrelated families with three different biallelic variants in FILIP1 gene (including the variant reported in the patient from PMID:36344539) and presenting with an overlapping phenotype with congenital contractures affecting shoulder, elbow, hand, hip, knee and foot as well as scoliosis, reduced palmar and plantar skin folds, microcephaly and facial dysmorphism.; to: PMID:36344539 reported a single male with biallelic variant in FILIP1 (c.2665C > T/ p.Arg889Ter) gene and presenting with distal arthrogryposis with contractures of the knees and elbows, congenital clubfoot, muscular hypotonia, and mild learning disability.

PMID:37163662 reported five individuals from four unrelated families with four different biallelic variants, out of which three individuals from two different families presented with congenital onset of contractures.

This gene has not yet been associated with relevant phenotypes either in OMIM or in Gene2Phenotype.
Arthrogryposis v3.102 EBP Arina Puzriakova Added comment: Comment on list classification: EBP will be flagged for GMS review to assess whether there is enough evidence and potential clinical value to rate as Green on this panel.

Flexion contractures may occur is a subset of patients with variants in this gene. However, as other manifestations such as skeletal malformations and skin abnormalities represent more prominent features of the disorder, it is less likely that cases would be tested under the Arthrogryposis panel. EBP is already Green on other relevant panels (Skeletal dysplasia v2.100, Palmoplantar keratodermas v1.7, etc).
