Histological findings include slightly enlarged chondrocytes and hypercellularity. The prevalence is unknown. The disorder is transmitted as an autosomal dominant trait and is caused by mutations in the C-propeptide domain of the <i>COL2A1</i> gene. Although PLSD-T is generally lethal, survival to adulthood has been reported in two families.","GARD_Name__c":"Platyspondylic dysplasia, Torrance type","GARD_Synonym__c":"platyspondylic dysplasia, torrance-luton type; platyspondylic lethal skeletal dysplasia, torrance type; platyspondylic skeletal dysplasia, torrance type; plsd-t; plsdt","Curated_Disease_Description_Source__c":"ORPHA:85166","Curated_Disease_Description__c":"Platyspondylic dysplasia, Torrance type is a severe disorder of bone growth.
