Our case presented with severe short stature and skeletal deformities with Turner syndrome (TS) and a SHOX gene abnormality due to a downstream allele deletion in her normal X chromosome. [ncbi.nlm.nih.gov]

The SHOX (short-stature homeobox-containing) gene is present in the locus Ypter-p11.2 and Xpter-p22.32. The SHOX gene encodes isoforms of a homeodomain transcription factor important in human limb development. [ashg.org]

All children of an individual with LMD and an unaffected parent will present with LWD. Management and treatment There is no effective treatment for LMD. [rarediseases.info.nih.gov]

• Short Stature

  Homozygous mutation of the short stature homeobox-containing gene, SHOX, results in Langer mesomelic dysplasia (LMD). [ncbi.nlm.nih.gov]

  Pathogenesis [ edit ] At the core of the disorder there is a homozygous or compound heterozygous mutation or deletion of the SHOX (Short Stature Homeobox), SHOXY (Short Stature Homeobox Y-linked) or PAR1 (where SHOX enhancer elements are located) genes [en.wikipedia.org]

  SHOX haploinsufficiency has been implicated in three human growth disorders: Turner syndrome, idiopathic short stature, and Leri-Weill dyschondrosteosis. [ashg.org]

• Short Arm

  Abstract Haploinsufficiency of SHOX on the short arm pseudoautosomal region (PAR1) leads to Leri-Weill dyschondrosteosis (LWD), and nullizygosity of SHOX results in Langer mesomelic dysplasia (LMD). [ncbi.nlm.nih.gov]

  In most cases, the disease is caused by a haploinsufficiency of the SHOX gene, which is located in the pseudo-autosomal region (PAR1) on the short arm of both sex chromosomes. [medical-genetics.de]

Prognosis The short stature and limb deformities are severe but life expectancy is normal. Last updated: 1/1/2020 [rarediseases.info.nih.gov]

Prognosis The severity of effects of LWD varies widely, so prognoses for people with the syndrome also vary. Severe Madelung deformity may require surgery. However, individuals with LWD have an excellent prognosis, and most have normal lives. [encyclopedia.com]

Prognosis Prognosis depends on the precise nature of the specific osteochondrodysplasia. Among infants with skeletal dysplasias detected at birth, approximately 13% are stillborn and 44% die during the perinatal period. [patient.info]
