Physical characteristics include moderate short-stature (dwarfism); moderate to severe spinal deformities; barrel-chest; disproportionately short trunk and neck;disproportionatelylong arms,and premature osteoarthritis, especially in the hip joints. Final male adult height ranges from 4 feet 10 inches to 5 feet 6 inches. Other skeletal features of this condition include decreased mobility of the elbow and hip joints, arthritis, and abnormalities of the hip joint which causes the upper leg bones to turn inward. This condition is caused by mutations in the TRAPPC2 gene and is inherited in an X-linked recessive pattern.","GARD_Name__c":"Spondyloepiphyseal dysplasia tarda, X-linked","GARD_Synonym__c":"sed tarda, x-linked; sedt - spondyloepiphyseal dysplasia tarda; spondyloepiphyseal dysplasia tarda, x-linked recessive","Curated_Disease_Description_Source__c":"GARD:0004985","Curated_Disease_Description__c":"X-linked spondyloepiphyseal dysplasia tarda is a condition that impairs bone growth and occurs almost exclusively in  males. The name of the condition indicates that it affects the bones of the spine (spondylo-) and the ends of long bones (epiphyses) in the arms and legs. 'Tarda' indicates that signs and symptoms of this condition are not present at birth, but appear later in childhood, typically between ages 6 and 10. Males with X-linked spondyloepiphyseal dysplasia tarda have skeletal abnormalities and short stature. Affected boys grow steadily until late childhood, when their growth slows. Their adult height ranges from 4 feet 6 inches (137 cm) to 5 feet 4 inches (163 cm). Impaired growth of the spinal bones (vertebrae) primarily causes the short stature. Spinal abnormalities include flattened vertebrae (platyspondyly) with hump-shaped bulges, progressive thinning of the discs between vertebrae, and an abnormal curvature of the spine (scoliosis or kyphosis). These spinal problems also cause back pain in people with this condition. Individuals with X-linked spondyloepiphyseal dysplasia tarda have a short torso and neck, and their arms are disproportionately long compared to their height. Other skeletal features of X-linked spondyloepiphyseal dysplasia tarda include an abnormality of the hip joint that causes the upper leg bones to turn inward (coxa vara); multiple abnormalities of the epiphyses, including a short upper end of the thigh bone (femoral neck); and a broad, barrel-shaped chest. A painful joint condition called osteoarthritis that typically occurs in older adults often develops in early adulthood in people with X-linked spondyloepiphyseal dysplasia tarda and worsens over time, most often affecting the hips, knees, and shoulders.","Curated_USA_Estimate_Source__c":null,"Curated_USA_Estimate__c":null,"Age_at_Onset_Snippet_Text__c":null,"SourceID__c":"OMIM:313400","Deprecated__c":"No","Disease_Concept_Type__c":"Rare Disease Entity","MONDO_ID__c":"MONDO:0010737","ORPHANET_ID__c":null,"Replaced_By_ID__c":null,"Display_Spanish_Disease_Name__c":null,"Spanish_Description_Source__c":null,"Spanish_Description__c":null,"Spanish_Disease_Name__c":null,"Spanish_GARD_Synonym__c":null,"Category_Linearization__c":null,"icd10_id__c":null,"mesh_id__c":null,"omim_id__c":null,"snomed_id__c":null,"umls_id__c":null,"GARD_Disease__c":[{"Curated_Disease_Description__c":"X-linked spondyloepiphyseal dysplasia tarda is a condition that impairs bone growth and occurs almost exclusively in  males.
