(dis'kon-dros'tē-ō'sis), [MIM*127300]
A skeletal dysplasia, more severe in females and with a female preponderance, characterized by bowing of radius, dorsal dislocation of the distal ulna with limited movement of the elbow and wrist (wrist deformity is called Madelung deformity), and mesomelic dwarfism; dominant inheritance, caused by mutation in the short stature homeobox gene (SHOX) on the pseudoautosomal region of Xp. Langer mesomelic dysplasia, the homozygous form of dyschondrosteosis, is also caused by homozygous mutations in the SHOX gene.
[dys- + G. chondros, cartilage, + osteon, bone, + -osis, condition]

Characterization of SHOX deletions in Leri-Weill dyschondrosteosis (LWD) reveals genetic heterogeneity and no recombination hotspots.
Heterozygous carriers of SHOX mutations may be minimally affected or may present with disproportionately short stature, Madelung deformity and other radiographic findings, as in Leri-Weill dyschondrosteosis (LWD).
The prominent Madelung deformity (shortening and bowing of the radii and triangulation of the distal radial epiphysis producing an ulnar slant to the articular surface) of the distal radius and ulna is a well-described feature of dyschondrosteosis (Leri-Weill disease).
