Impairment of SHOX nuclear localization as a cause for Léri-Weill syndrome.

A novel point mutation A170P in the SHOX gene defines impaired nuclear translocation as a molecular cause for Léri-Weill dyschondrosteosis and Langer dysplasia.

Short stature and dysmorphology associated with defects in the SHOX gene.

Since its discovery in 1997, knowledge about the SHOX gene ( Short stature HOmeoboX-containing gene) has rapidly advanced. Although originally described as causing idiopathic short stature, SHOX mutations are also responsible for growth retardation in Léri-Weill dyschondrosteosis, Langer mesomelic dysplasia and Turner syndrome. Furthermore, SHOX has a broad functional scope and leads to a varie...

SHOX mutations in a family and a fetus with Langer mesomelic dwarfism.

Léri-Weill dyschondrosteosis (LWD) and Langer mesomelic dysplasia (LMD) are caused by mutations in the SHOX gene. LWD results from haploinsufficiency and is dominantly inherited, while the more severe LMD results from the homozygous loss of SHOX. We describe a family and fetus with two SHOX mutations. Several relatives carry an approximately 200 kb interstitial deletion that includes the whole ...

Identification of Novel SHOX Target Genes in the Developing Limb Using a Transgenic Mouse Model

Deficiency of the human short stature homeobox-containing gene (SHOX) has been identified in several disorders characterized by reduced height and skeletal anomalies such as Turner syndrome, Léri-Weill dyschondrosteosis and Langer mesomelic dysplasia as well as isolated short stature. SHOX acts as a transcription factor during limb development and is expressed in chondrocytes of the growth plat...

Comparative transgenic analysis of enhancers from the human SHOX and mouse Shox2 genomic regions.

Disruption of presumptive enhancers downstream of the human SHOX gene (hSHOX) is a frequent cause of the zeugopodal limb defects characteristic of Léri-Weill dyschondrosteosis (LWD). The closely related mouse Shox2 gene (mShox2) is also required for limb development, but in the more proximal stylopodium. In this study, we used transgenic mice in a comparative approach to characterize enhancer s...
