It can be potentially life-threatening. MMDS5 affects the brain and nervous system of infants and young children. The condition gets worse over time. It is characterized by seizures, muscle stiffness, and an inability to control muscles. People with MMDS5 also often have issues with their nerves. These include missing or damaged protective nerve coatings called myelin (leukodystrophy). Nerve issues also include having nerves that go to places they typically don’t go. Often, people with this disease have too much lactic acid in their blood. MMDS5 is caused by mutations in the ISCA1 gene. It is inherited in an autosomal recessive pattern. This means two copies of the mutated gene are required to cause the disease.","Curated_USA_Estimate_Source__c":null,"Curated_USA_Estimate__c":"1,000","Age_at_Onset_Snippet_Text__c":"as an Infant","SourceID__c":"ORPHA:569274","Deprecated__c":"No","Disease_Concept_Type__c":"Rare Disease Entity","MONDO_ID__c":"MONDO:0033282","ORPHANET_ID__c":"ORPHA:569274","Replaced_By_ID__c":null,"Display_Spanish_Disease_Name__c":"Síndrome de disfunción mitocondrial múltiple tipo 5","Spanish_Description_Source__c":null,"Spanish_Description__c":null,"Spanish_Disease_Name__c":"síndrome de disfunción mitocondrial múltiple tipo 5","Spanish_GARD_Synonym__c":"deficiencia de isca1; mmds5","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":"Multiple mitochondrial dysfunctions syndrome type 5 (MMDS5) is a rare genetic metabolic disease.
