Genetics Home Reference : ²⁵ CHST3-related skeletal dysplasia is a genetic condition characterized by bone and joint abnormalities that worsen over time. Affected individuals have short stature throughout life, with an adult height under 4 and a half feet. Joint dislocations, most often affecting the knees, hips, and elbows, are present at birth (congenital). Other bone and joint abnormalities can include an inward- and upward-turning foot (clubfoot), a limited range of motion in large joints, and abnormal curvature of the spine. The features of CHST3-related skeletal dysplasia are usually limited to the bones and joints; however, minor heart defects have been reported in a few affected individuals. CHST3 CHST3 Researchers have not settled on a preferred name for this condition. It is sometimes known as autosomal recessive Larsen syndrome based on its similarity to another skeletal disorder called Larsen syndrome. Other names that have been used to describe the condition include spondyloepiphyseal dysplasia, Omani type; humero-spinal dysostosis; and chondrodysplasia with multiple dislocations. Recently, researchers have proposed the umbrella term CHST3-related skeletal dysplasia to refer to bone and joint abnormalities resulting from mutations in the CHST3 gene. CHST3 CHST3

MalaCards based summary : Spondyloepiphyseal Dysplasia with Congenital Joint Dislocations, also known as spondyloepiphyseal dysplasia, is related to schimke immunoosseous dysplasia and spondyloepiphyseal dysplasia congenita, and has symptoms including respiratory distress and waddling gait. An important gene associated with Spondyloepiphyseal Dysplasia with Congenital Joint Dislocations is CHST3 (Carbohydrate Sulfotransferase 3), and among its related pathways/superpathways are Glycosaminoglycan biosynthesis - chondroitin sulfate / dermatan sulfate and Endochondral Ossification. The drugs Losartan and Angiotensin II have been mentioned in the context of this disorder. Affiliated tissues include bone, heart and skin, and related phenotypes are hypertelorism and genu valgum

Disease Ontology : ¹² A spondyloepimetaphyseal dysplasia that is characterized by short stature of prenatal onset, joint dislocations (knees, hips, radial heads), club feet, and limitation of range of motion that can involve all large joints.

NIH Rare Diseases : ⁵³ Spondyloepiphyseal dysplasia (SED) is a group of rare genetic conditions that affect bone growth in the spine, arms, and legs. Other features include problems with vision and hearing, clubfeet, cleft palate, arthritis, and difficulty with breathing as curvature of the spine progresses. There are two main types of SED, spondyloepiphyseal dysplasia congenita (which is present from bith) and spondyloepiphyseal dysplasia tarda (which develops later in childhood or adolescence). Spondyloepiphyseal dysplasia is caused by mutations in genes that are responsible for making proteins that are needed for the creation of bone and cartilage. Most cases are due to a new (de novo) mutation, although it can be passed down through families. Treatment is aimed at managing the symptoms and associated complications as they arise.

OMIM : ⁵⁷ Although patients with mutations in the CHST3 gene may initially be given varying diagnostic labels, they have similar clinical features, including dislocation of the knees and/or hips at birth, clubfoot, elbow joint dysplasia with subluxation and limited extension, short stature, and progressive kyphosis developing in late childhood. The disorder is usually evident at birth, with short stature and multiple joint dislocations or subluxations that dominate the neonatal clinical and radiographic picture, and affected individuals may receive an initial clinical diagnosis of Larsen syndrome (see 245600) or humerospinal dysostosis. During childhood, the dislocations improve, both spontaneously and with surgical treatment, and features of spondyloepiphyseal dysplasia become apparent, leading to arthritis of the hips and spine with intervertebral disc degeneration, rigid kyphoscoliosis, and trunk shortening by late childhood; at this stage, the clinical features are those previously described as the Omani type of SED (summary by Unger et al., 2010).

KEGG : ³⁷ Spondyloepiphyseal dysplasia with congenital joint dislocations (SEDCJD) is also known as SED Omani type. Knees, hip and elbow dislocations are common. Thoracic kyphoscoliosis develops in late childhood. Affected individuals are homozygous for a missense mutation of CHST3 encoding the enzyme chondroitin 6-O-sulfotransferase-1 (C6ST-1).

UniProtKB/Swiss-Prot : ⁷⁴ Spondyloepiphyseal dysplasia with congenital joint dislocations: A bone dysplasia clinically characterized by dislocation of the knees and/or hips at birth, clubfoot, elbow joint dysplasia with subluxation and limited extension, short stature, and progressive kyphosis developing in late childhood. The disorder is usually evident at birth, with short stature and multiple joint dislocations or subluxations that dominate the neonatal clinical and radiographic picture. During childhood, the dislocations improve, both spontaneously and with surgical treatment, and features of spondyloepiphyseal dysplasia become apparent, leading to arthritis of the hips and spine with intervertebral disk degeneration, rigid kyphoscoliosis, and trunk shortening by late childhood.
