Other symptoms might include muscle weakness and wasting (atrophy), and protrusion of part of the stomach through the diaphragm in the chest cavity (hiatal hernia). Classical-like EDS is caused by genetic changes in both copies of the TNXB gene and is inherited in an autosomal recessive manner. However, some individuals with a genetic change in only one copy of the TNXB gene can have symptoms similar to EDS hypermobility type including joint hypermobility and soft skin. Some individuals with classical-like EDS can have larger deletions of genetic material including other genes. These individuals may have additional symptoms.","GARD_Name__c":"Ehlers-Danlos syndrome due to tenascin-X deficiency","GARD_Synonym__c":"classical-like eds type 1; classical-like ehlers-danlos syndrome type 1; cleds type 1; eds due to tnx deficiency; eds, classic-like type; edscll1; ehlers-danlos syndrome classic-like type; ehlers-danlos syndrome, classic-like; ehlers-danlos syndrome, classic-like type; ehlers-danlos syndrome, classic-like, 1; tnx deficiency","Curated_Disease_Description_Source__c":"GARD:0008507","Curated_Disease_Description__c":"The clinical features of TNXB-related classical-like Ehlers-Danlos syndrome (clEDS) strongly resemble those seen in classic EDS (cEDS).

There are also several other distinguishing clinical findings including anomalies of feet and hands, edema in the legs in the absence of cardiac failure, mild proximal and distal muscle weakness, and axonal polyneuropathy. Vaginal, uterine, and/or rectal prolapse can also occur. Tissue fragility with resulting rupture of the trachea, esophagus, and small and large bowel has been reported. Vascular fragility causing a major event occurs in a minority of individuals. Significant variability in the severity of musculoskeletal symptoms and their effect on day-to-day function between unrelated affected individuals as well as among affected individuals in the same family has been reported. Fatigue has been reported in more than half of affected individuals. The severity of symptoms in middle-aged individuals can range from joint hypermobility without complications to being wheelchair-bound as a result of severe and painful foot deformities and fatigue.","Curated_USA_Estimate_Source__c":null,"Curated_USA_Estimate__c":"1,000","Age_at_Onset_Snippet_Text__c":"from Birth to Childhood","SourceID__c":"ORPHA:230839","Deprecated__c":"No","Disease_Concept_Type__c":"Rare Disease Entity","MONDO_ID__c":"MONDO:0011670","ORPHANET_ID__c":"ORPHA:230839","Replaced_By_ID__c":null,"Display_Spanish_Disease_Name__c":"Síndrome de ehlers-danlos similar al tipo clásico 1","Spanish_Description_Source__c":null,"Spanish_Description__c":null,"Spanish_Disease_Name__c":"síndrome de ehlers-danlos similar al tipo clásico 1","Spanish_GARD_Synonym__c":"sed similar al tipo clásico 1; síndrome de ehlers-danlos por deficiencia de tenascina-x","Category_Linearization__c":"ORPHA:98023","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":"The clinical features of TNXB-related classical-like Ehlers-Danlos syndrome (clEDS) strongly resemble those seen in classic EDS (cEDS).
