Summaries for Dyssegmental Dysplasia, Silverman-Handmaker Type

About this section
NIH Rare Diseases : 53 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 1865Disease definitionDyssegmental dysplasia, Silverman-Handmaker type is a rare, genetic, primary bone dysplasia disorder, and lethal form of neonatal short-limbed dwarfism, characterized by anisospondyly, severe short stature and limb shortening, metaphyseal flaring and distinct dysmorphic features (i.e. flat facial appearance, abnormal ears, short neck, narrow thorax). Additional features may include other skeletal findings (e.g. joint contractures, bowed limbs, talipes equinovarus) and urogenital and cardiovascular abnormalities.Visit the Orphanet disease page for more resources.

MalaCards based summary : Dyssegmental Dysplasia, Silverman-Handmaker Type, is also known as ddsh. An important gene associated with Dyssegmental Dysplasia, Silverman-Handmaker Type is HSPG2 (Heparan Sulfate Proteoglycan 2). Affiliated tissues include bone and eye, and related phenotypes are respiratory insufficiency and inguinal hernia

Disease Ontology : 12 An osteochondrodysplasia characterized by short-limbed dwarfism, anisospondyly, and neonatal lethality that has material basis in homozygous or compound heterozygous mutation in the HSPG2 gene on chromosome 1p36.

UniProtKB/Swiss-Prot : 75 Dyssegmental dysplasia Silverman-Handmaker type: The dyssegmental dysplasias are rare, autosomal recessive skeletal dysplasias with anisospondyly and micromelia. There are two recognized types: the severe, lethal DDSH and the milder Rolland-Desbuquois form. Individuals with DDSH also have a flat face, micrognathia, cleft palate and reduced joint mobility, and frequently have an encephalocoele. The endochondral growth plate is short, the calcospherites (which are spherical calcium-phosphorus crystals produced by hypertrophic chondrocytes) are unfused, and there is mucoid degeneration of the resting cartilage.
