People with prolidase deficiency are susceptible to severe infections of the skin or ears, or potentially life-threatening respiratory tract infections. Some individuals with prolidase deficiency have chronic lung disease. Characteristic facial features in people with prolidase deficiency include prominent eyes that are widely spaced (hypertelorism), a high forehead, a flat bridge of the nose, and a very small lower jaw and chin (micrognathia). Affected children may experience delayed development, and about 75 percent of people with prolidase deficiency have intellectual disability that may range from mild to severe. People with prolidase deficiency often develop skin lesions, especially on their hands, feet, lower legs, and face. The severity of the skin involvement, which usually begins during childhood, may range from a mild rash to severe skin ulcers. Skin ulcers, especially on the legs, may not heal completely, resulting in complications including infection and amputation. The severity of symptoms in prolidase deficiency varies greatly among affected individuals. Some people with this disorder do not have any symptoms. In these individuals the condition can be detected by laboratory tests such as newborn screening tests or tests offered to relatives of affected individuals.","Curated_USA_Estimate_Source__c":null,"Curated_USA_Estimate__c":"1,000","Age_at_Onset_Snippet_Text__c":"at a variety of ages","SourceID__c":"ORPHA:742","Deprecated__c":"No","Disease_Concept_Type__c":"Rare Disease Entity","MONDO_ID__c":"MONDO:0008221","ORPHANET_ID__c":"ORPHA:742","Replaced_By_ID__c":null,"Display_Spanish_Disease_Name__c":"Deficiencia de prolidasa","Spanish_Description_Source__c":"ORPHA:742","Spanish_Description__c":"La deficiencia de prolidasa es un trastorno hereditario del metabolismo de los péptidos caracterizado por lesiones cutáneas graves, infecciones recurrentes (que afectan principalmente a la piel y al sistema respiratorio), rasgos faciales dismórficos, deterioro cognitivo variable y esplenomegalia.","Spanish_Disease_Name__c":"deficiencia de prolidasa","Spanish_GARD_Synonym__c":null,"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":"Prolidase deficiency is a disorder that causes a wide variety of symptoms.
