Presentation
A 27-year-old primigravida patient with diastrophic dysplasia (DTD) presented to our obstetrics clinic at 8 weeks' gestational age. [ncbi.nlm.nih.gov]
Entire Body System
-
Localized Edema
The thickness of the joint cartilage was diminished and signs of early osteoarthritis, including bone cysts and local edema, were common. The ligamentum teres was visible in only 24% of patients, suggesting abnormality of the ligamentous structures. [ncbi.nlm.nih.gov]
Jaw & Teeth
-
Periodontitis
The level of oral hygiene was evaluated with caries (DMF) and periodontal (GBI) indices. Cleft palate was recorded in 56% and hypodontia (excluding third molars) in 31% of the patients. Dental age was retarded. [ncbi.nlm.nih.gov]

Skeletal Dysplasia
Patients at risk for skeletal dysplasia could benefit from the enhancements of ultrasound techniques. An early diagnosis of diastrophic dysplasia can be reached at the and of the first trimester of pregnancy, using TVS. [ncbi.nlm.nih.gov]

Hearing impairment not usual (it is related to fusion of ossicles). Some patients present deformities of larynx and upper airways (laryngo and tracheomalacia). They can develop severe respiratory insufficiency. [peachynay.tripod.com]
However, according to reports in the literature, other affected infants and children may experience hearing impairment due to such auditory canal stenosis or abnormal fusion or absence of the three tiny bones (auditory ossicles) in the middle ear that [rarediseases.org]

Average Intelligence
Most people with diastrophic dysplasia have average intelligence and a normal life expectancy and can expect to lead productive lives. All A to Z dictionary entries are regularly reviewed by KidsHealth medical experts. [kidshealth.org]
Treatment
The SRS-24 yielded 92 (79-103) points for the brace treatment and 93 (73-114) points for the surgical group, respectively. CONCLUSION: Brace treatment does not prevent progression of the spinal deformity in patients with DD. [ncbi.nlm.nih.gov]

Prognosis
Prenatal diagnosis of this condition allowed a more realistic interpretation of the prognosis, and of the couple's reproductive future. [ncbi.nlm.nih.gov]
Prognosis In the absence of severe complications (spinal cord compression) associated with spinal malformations, life expectancy is good but the short stature and deformity are usually severe. [orpha.net]
Treatment and prognosis Life expectancy and mental function are usually normal. In view of its autosomal recessive inheritance, there is a 25% change of recurrence. [radiopaedia.org]
Etiology
Abstract Patients with diastrophic dysplasia have walking difficulties of obscure etiology; some are even wheelchair-bound. [ncbi.nlm.nih.gov]
Etiology The syndrome is caused by mutations in the SLC26A2 (or diastrophic dysplasia sulfate transporter; DTDST ) gene (5q31-q34), which encodes a sulfate transporter that is predominantly expressed in the cartilage. [orpha.net]
Epidemiology
Summary Epidemiology Prevalence is estimated at 1-1.3/100,000. The disorder affects both males and females. Clinical description At birth, infants have bilateral clubfoot, short limb deformation of the wrists and abducted thumbs. [orpha.net]

Prevention
This paper presents a novel but simple approach to the compression of auricular swelling in the setting of diastrophic dysplasia, using conforming molds with the goal of preventing permanent deformity. [ncbi.nlm.nih.gov]
Mutations in the SLC26A2 gene alter the structure of developing cartilage, preventing bones from forming properly and resulting in the skeletal problems characteristic of diastrophic dysplasia. [en.wikipedia.org]
