Arthrogryposis v9.31 DDR2 Ida Ertmanska edited their review of gene: DDR2: Changed phenotypes to: Warburg-Cinotti syndrome, OMIM:618175
Arthrogryposis v9.31 DDR2 Ida Ertmanska Classified gene: DDR2 as Amber List (moderate evidence)
Arthrogryposis v9.31 DDR2 Ida Ertmanska Added comment: Comment on list classification: There are at least 6 individuals reported in literature with heterozygous missense variants in DDR2 and Warburg-Cinotti syndrome - with the main feature being contractures. Contractures are not a feature of DDR2-related recessive disease. Hence, DDR2 should be updated to Green at the next GMS update with MOI MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted.

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).
