Presentation
Molecular investigations in this South African family are currently underway but at present the basis defect of brachyolmia remains unknown. [ncbi.nlm.nih.gov]
Rounding of the anterior and posterior vertebral borders is present. The Autosomal dominant type: symptoms somewhat milder than in the other types. Most cases have scoliosis or kyphosis. [answers.com]

Disproportionate Short Stature
The disorder is characterized by disproportionate short stature with short trunk, scoliosis and platyspondyly. The phenotypic variability and long-term natural course remain inadequately characterized. [ncbi.nlm.nih.gov]

Precocious Puberty
More recently, clinicians from Western Europe have described a girl of Turkish origin with PAPSS2 sequence variants who suffered from precocious puberty and bone problems, although her skeletal defects were far milder than those found in other people [riken.jp]

Corneal Opacity
Toledo type--radiographically similar to Hobaek type but also associated with corneal opacities and precocious ossification of costal cartilage. It is uncertain as to whether this represents variability or heterogeneity. 2. [ncbi.nlm.nih.gov]
The Toledo form is distinguished by the presence of corneal opacities and precocious calcification of the costal cartilage. Brachyolmia, recessive Hobaek type: A rare bone disorder characterized by a short trunk dwarfism. [checkorphan.org]
The Toledo type: probably identical to the Hobaek type with regard to the skeletal and vertebral changes, but patients also have abnormal excretion of glycosaminoglycans and peripheral punctate corneal opacities. [answers.com]

Coxa Valga
Bilateral coxa valga and mild acetabular irregularities were noticed on pelvic radiographies. Levels of chondroitin and heparan sulphate as well as the glycosaminoglycan/creatinine ratio were elevated in the 24-hour urine specimen. [ncbi.nlm.nih.gov]

Normal Stature
The other members of the family were of normal stature and appearance. The proband's growth hormone stimulation tests, thyroid function tests, sex steroids, gonadotropins and blood biochemistry were found normal. [ncbi.nlm.nih.gov]

Management and treatment No specific treatment is currently available for this disease. Prognosis The prognosis for patients with brachyolmia is generally very good. [orpha.net]
Although there is no specific treatment for any of the brachyolmias, our patient is considering decompressive spinal surgery for palliation of his symptoms. [theassr.org]

Etiology
Etiology A number of different mutations in the PAPSS2 gene (10q23.2-q23.3) have been reported in affected patients. PAPPS2 encodes PAPS (3'-phosphoadenosine 5'-phosphosulfate) synthase 2. [orpha.net]
As a likely etiology, a disturbance in chondroitin sulfate synthesis is suggested. [link.springer.com]
Etiology Mutations in the PAPSS2 gene (10q24) have been found in patients with AR brachyolmia, Hobaek/Toledo type, and in the TRPV4 gene (12q24.1) in patients with AD brachyolmia. Precise pathogenesis is not well understood. [rarediseases.info.nih.gov]

Summary Epidemiology The precise prevalence of this form of brachyolmia is not known. About 20 cases have been reported. Cases have been reported in various ethnic groups (Japan, Korea, Turkey), sometimes related to consanguineous unions. [orpha.net]

Pathophysiology
Molecular and Systemic Pathophysiology Qualitative abnormal excretion of glycosaminoglycans is described in some patients. As a likely etiology, a disturbance in chondroitin sulfate synthesis is suggested. [link.springer.com]

However, given the complexity of the bone structures, the diverse origins of its components and the heterogeneity of the underlying pathophysiological mechanisms, the difficulty of identifying the disorders that were true variants eliminating unfounded [zdoc.site]
