These types are known as classic infantile-onset, non-classic infantile-onset, and late-onset. The classic form of infantile-onset Pompe disease begins within a few months of birth. Infants with this disorder typically experience muscle weakness (myopathy), poor muscle tone (hypotonia), an enlarged liver (hepatomegaly), and heart defects. Affected infants may also fail to gain weight and grow at the expected rate (failure to thrive) and have breathing problems. If untreated, this form of Pompe disease leads to death from heart failure in the first year of life. The non-classic form of infantile-onset Pompe disease usually appears by age 1. It is characterized by delayed motor skills (such as rolling over and sitting) and progressive muscle weakness. The heart may be abnormally large (cardiomegaly), but affected individuals usually do not experience heart failure. The muscle weakness in this disorder leads to serious breathing problems, and most children with non-classic infantile-onset Pompe disease live only into early childhood. The late-onset type of Pompe disease may not become apparent until later in childhood, adolescence, or adulthood. Late-onset Pompe disease is usually milder than the infantile-onset forms of this disorder and is less likely to involve the heart. Most individuals with late-onset Pompe disease experience progressive muscle weakness, especially in the legs and the trunk, including the muscles that control breathing. As the disorder progresses, breathing problems can lead to respiratory failure.","Curated_USA_Estimate_Source__c":null,"Curated_USA_Estimate__c":"5,000","Age_at_Onset_Snippet_Text__c":"at a variety of ages","SourceID__c":"ORPHA:365","Deprecated__c":"No","Disease_Concept_Type__c":"Rare Disease Grouping","MONDO_ID__c":"MONDO:0009290","ORPHANET_ID__c":"ORPHA:365","Replaced_By_ID__c":null,"Display_Spanish_Disease_Name__c":"Enfermedad de almacenamiento de glucógeno por deficiencia de maltasa ácida","Spanish_Description_Source__c":"ORPHA:365","Spanish_Description__c":"Es una enfermedad de almacenamiento lisosomal poco frecuente caracterizada por el acúmulo lisosomal de glucógeno, particularmente en el músculo esquelético, cardíaco y respiratorio, así como en el hígado y el sistema nervioso, debido a la deficiencia de maltasa ácida.
