Skeletal abnormalities are also common in this condition. The rate at which symptoms worsen varies among affected individuals. People with MPS VI generally do not display any features of the condition at birth. They often begin to show signs and symptoms of MPS VI during early childhood. The features of MPS VI affect many bodily systems, including  skeletal, cardiac, and respiratory. MPS VI causes various skeletal abnormalities, including a large head (macrocephaly) with a buildup of fluid in the brain (hydrocephalus), distinctive-looking facial features that are described as 'coarse,' and a large tongue (macroglossia). Other skeletal features include short stature, joint deformities (contractures) that affect mobility, and dysostosis multiplex, which refers to multiple skeletal abnormalities seen on x-ray. Carpal tunnel syndrome develops in many children with MPS VI and is characterized by numbness, tingling, and weakness in the hands and fingers. People with MPS VI may develop a narrowing of the spinal canal (spinal stenosis) in the neck, which can compress and damage the spinal cord.  Cardiac problems in people with MPS VI typically includes heart valve abnormalities. Respiratory abnormalities in this condition may involve the airway becoming narrow, which leads to frequent upper respiratory infections and short pauses in breathing during sleep (sleep apnea).  Other features of MPS VI include an enlarged liver and spleen (hepatosplenomegaly), and a soft out-pouching around the belly-button (umbilical hernia) or lower abdomen (inguinal hernia). The clear covering of the eye (cornea) typically becomes cloudy, which can cause significant vision loss. People with MPS VI may also have recurrent ear infections and hearing loss. Unlike other types of mucopolysaccharidosis, MPS VI does not affect intelligence. The life expectancy of individuals with MPS VI depends on the severity of symptoms. Without treatment, severely affected individuals may survive only until late childhood or adolescence. Those with milder forms of the disorder usually live into adulthood, although their life expectancy may be reduced. Heart disease and airway obstruction are major causes of death in people with MPS VI.","Curated_USA_Estimate_Source__c":null,"Curated_USA_Estimate__c":"5,000","Age_at_Onset_Snippet_Text__c":"as a Child","SourceID__c":"ORPHA:583","Deprecated__c":"No","Disease_Concept_Type__c":"Rare Disease Grouping","MONDO_ID__c":"MONDO:0009661","ORPHANET_ID__c":"ORPHA:583","Replaced_By_ID__c":null,"Display_Spanish_Disease_Name__c":"Mucopolisacaridosis tipo 6","Spanish_Description_Source__c":"ORPHA:583","Spanish_Description__c":"La mucopolisacaridosis de tipo 6 (MPS 6) es una enfermedad de almacenamiento lisosómico con afectación sistémica progresiva, asociada a un déficit de arilsulfatasa B (ASB) que conduce a una acumulación de dermatán sulfato.","Spanish_Disease_Name__c":"mucopolisacaridosis tipo 6","Spanish_GARD_Synonym__c":"deficiencia de arilsulfatasa b; deficiencia de arsb; deficiencia de asb; deficiencia de n-acetilgalactosamina 4-sulfatasa; enfermedad de maroteaux-lamy; mps6; mpsvi; mucopolisacaridosis tipo vi","Category_Linearization__c":"ORPHA:68367","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":"Mucopolysaccharidosis type VI (MPS VI), also known as Maroteaux-Lamy syndrome, is a progressive condition that causes many tissues and organs to enlarge, become inflamed or scarred, and eventually waste away (atrophy).
