Genes associados
1 gene identificado com associação a esta condição. Padrão de herança: Autosomal dominant.
Transcription factor that controls fundamental aspects of growth. Directly activates NPPB transcription in osteogenic cells (PubMed:11751690, PubMed:17881654). Preferentially binds DNA elements with the sequence 5'-TAATNNNATTA-3', possibly as a homodimer (PubMed:11751690)
Nucleus
Leri-Weill dyschondrosteosis
Dominantly inherited skeletal dysplasia characterized by moderate short stature predominantly because of short mesomelic limb segments. It is often associated with the Madelung deformity of the wrist, comprising bowing of the radius and dorsal dislocation of the distal ulna.

Phenotype Variations in a Family with Various Rearrangements in the Locus of the SHOX Gene.
The SHOX gene is located on both sex chromosomes, X and Y, within the pseudoautosomal region 1 (PAR1). Gross deletions at the SHOX locus lead to protein insufficiency and are manifested by growth disorders such as Leri-Weill dyschondrosteosis (LWD), Langer mesomelic dysplasia (LMD), and idiopathic short stature (ISS). In cases of the SHOX gene duplication, the phenotype may range from tall to short stature and LWD. This study describes a family with various SHOX locus alterations and diverse phenotypic manifestations. The proband inherited both deletion and duplication in the SHOX locus from her parents and shows typical features of LWD. The proband's father carries SHOX gene deletion and displays Madelung's deformity but normal height. The proband's mother has SHOX gene duplication without any abnormalities in phenotype. One of the proband's sons inherited deletion, while the other inherited duplication of the gene. Some family members also have the c.845_851dup variant in the CYP26C1 gene, previously described as a modifier of the SHOX gene. It is difficult to assess its effect. At present, it is not possible to predict the future phenotype of the proband's children due to the high phenotypic variability associated with SHOX locus alterations.
Madelung Deformity: A Current Concepts Review.
Madelung deformity is a rare congenital wrist deformity characterized by growth disturbance of the volar-ulnar aspect of the distal radial physis, leading to progressive wrist deformity, pain, and stiffness. Madelung deformity is frequently associated with genetic conditions such as Leri-Weill dyschondrosteosis and Turner syndrome, and more recently, mutations in the GNAS gene have been implicated. Diagnosis is based on clinical findings and radiographic criteria, with plain radiographs demonstrating characteristic volar-ulnar radial curvature, positive ulnar variance, and carpal subluxation. Advanced imaging modalities enhance the characterization of complex deformities and aid in surgical planning. In skeletally immature patients, radial physiolysis with Vickers ligament release can prevent deformity progression. For skeletally mature patients with pain and functional limitations, corrective osteotomies of the distal radius, often combined with ulnar procedures, are the mainstay of treatment. Advances in three-dimensional surgical planning and custom cutting guides have improved the precision and reproducibility of complex reconstructions. Long-term outcome data remain limited and heterogeneous because of variability in patient presentation and surgical techniques, although many studies report improvements in pain, function, and radiographic alignment. Continued emphasis on standardized outcome reporting and collaborative research will improve evidence-based care and patient counseling for this complex deformity.
New Insights Into Changes in the DNA Methylation Pattern of the SHOX Gene in Patients With Léri-Weill Dyschondrosteosis.
SHOX gene haploinsufficiency is associated with Léri-Weill dyschondrosteosis (LWD) or idiopathic short stature (ISS) and could be caused by the structural and point mutations in the coding region and by the deletions in SHOX gene regulatory sequences. The role of the duplications in regulatory sequences is ambivalent. The unanswered question is what the role of changes in SHOX gene methylation is and if they could arise as a result of SHOX area duplication. Material consisted of DNA samples from 20 LWD patients with duplication involving SHOX regulatory elements, 30 patients with LWD/ISS phenotype without any known causal mutation in the SHOX region, and 23 healthy individuals as controls. We investigated the DNA methylation status of two CpG islands in the upstream region of the SHOX using bisulfite sequencing. Our results indicate that both CpG islands in the SHOX area show a lower level of methylation in LWD patients carrying duplications than in healthy individuals, but only one island showed a statistically significant difference. The results of methylation profiling of CpG islands in patients without any known causal mutation indicate that the methylation levels of the majority of patients differed in both CpG islands from the average of the group of healthy individuals by at least ±2 SD. However, the biological effect of these differences will probably be clinically insignificant due to the generally very low level of methylation.
Novel SHOX Variant in Léri-Weill Dyschondrosteosis with Madelung Deformity.
Mild phenotypes in patients with different deletions in the 3' enhancer region of SHOX.
Haploinsufficiency of the short stature homeobox-containing (SHOX) gene leads to a phenotypic spectrum ranging from Leri-Weill dyschondrosteosis (LWD) to SHOX-deficient short stature. SHOX nullizygosity leads to Langer mesomelic dysplasia. Pathogenic variants can include whole or partial gene deletions or duplications, point mutations within the coding sequence, and deletions of upstream and downstream regulatory elements. Here we report two families: a non-consanguineous family with a deletion downstream of SHOX, in which the homozygous proband presented with isolated Madelung deformity, without LWD or short stature, as well as a 9-year-old girl with Madelung deformities, mesomelia, a dominant family history of Madelung deformity and a heterozygous deletion of the CNE9 region in the 3' downstream region of SHOX. These case reports provide additional information on the effects of 3' downstream deletions of SHOX, by demonstrating the limited phenotype associated with the recurrent 47.5 kb deletion in a homozygous state and the CNE9 deletion in a heterozygous state.
