Caused by deletion of both SHOX alleles (complete SHOX deficiency) CLINICAL FEATURES 1. Dyschondrosteosis a. Mesomelic dwarfism (disproportionate short stature) b. Phenotypic inter- and intra-familial heterogeneity, a frequent finding Abstract We report on a girl presenting Leri-Weill dyschondrosteosis (LWD) due to deletion of the SHOX gene. Her family included individuals with short stature alone or with both short stature and The differential diagnosis of the various causes Leri-Weill syndrome, commonly known as dyschondrosteosis, is a rare and interesting form of short-limbed dwarfism of the mesomelic type, characterised by Madelung's deformity of both wrists, short forearms, and occasionally short legs.

Langer mesomelic dysplasia, also called mesomelic dwarfism of the hypoplastic ulna, fibula, and mandible type (Langer 1967), is a more severe form (homozygous state) of Leri-Weill dyschondrosteosis. Download reference work entry PDF. Leri-Weill dyschondrosteosis is characterized by SHOX deficiency, Madelung deformity, and mesomelic short stature. In addition, SHOX deficiency is associated with idiopathic short stature, Turner syndrome, and Langer mesomelic dysplasia. Léri-Weill dyschondrosteosis (LWD; or Léri-Weill syndrome) represents a short stature syndrome that is characterized by symmetric shortening of the forearms and lower legs and a bilateral shortening and bowing of the radius with a dorsal subluxation of the distal ulna (Madelung deformity) 10, 11. Prevalence of Léri-Weill dyschondrosteosis (LWD) is unknown. Clinical description The characteristics of mesomelic disproportion of the limbs and Madelung deformity may develop over time, presenting anywhere from birth to adolescence. Léri-Weill dyschondrosteosis or LWD is a rare pseudo autosomal dominant genetic disorder which results in dwarfism with short forearms and legs ( mesomelic dwarfism) and a bayonet-like deformity of the forearms ( Madelung's deformity ). [1] Contents 1 Causes 2 Diagnosis 3 Treatment 4 History 5 References 6 External links Causes [ edit] Leri-Weill dyschondrosteosis (LWD) is a dominantly inherited skeletal dysplasia characterized by short stature, mesomelia, and Madelung wrist deformity. Although the disorder occurs in both sexes, it is usually more severe in females, perhaps due to sex difference in estrogen levels. Haploinsufficiency of the short stature homeobox-containing (SHOX) gene causes Turner skeletal features, a certain proportion of idiopathic short stature and Leri-Weill dyschondrosteosis (LWD).
