Acute Infection in Mitochondrial Disease: Metabolism, Infection and Immunity
Trial Parameters
Brief Summary
Background: Mitochondrial disease is a rare disorder. It can cause poor growth, developmental delays, muscle weakness, and other symptoms. The disease is usually inherited. It can be present at birth or develop later in life. Infection is a major cause of disease and death in people with this disease. Researchers want to learn more about these infections and the declining health of people who have this disease. To do this, researchers will study the DNA of people who become ill. Their DNA will be compared to the DNA of their household/family members. Objective: To learn more about how genes affect people with mitochondrial disease. Eligibility: People age 2 months and older with mitochondrial disease and their household/family members. .\<TAB\> Design: Participants will complete a questionnaire about their health history. Their medical records may be reviewed. They will give a blood sample. If the participant becomes ill, they may have a videoconference with a doctor or nurse at the NIH to perform a physical exam. They may be contacted after their illness to give updates on their health. They may be asked to give extra blood samples or complete extra questionnaires. Participants genetic data will be put into a database. The data will be labeled with a code and not their name. The data will be shared with other researchers. Participation lasts about 1 year. This may be extended if the participant is very ill.
Eligibility Criteria
* INCLUSION CRITERIA: In order to be eligible to participate in this study, an individual must meet all of the following criteria: Group 1a 1. Participants must be two months of age or older. 2. Participants must have a diagnosis of mitochondrial disease based on a determination by a physician with expertise in genetics and/or neurology. Supportive evidence may include genetic testing, muscle biopsy, biochemical testing, neuroimaging or enzyme analysis consistent with mitochondrial disease. 3. At the time of enrollment, participants must have suspected or confirmed acute infection as defined by 1. New onset of any of the following symptoms within one month of enrollment without an alternative diagnosis: fever, cough, shortness of breath, fatigue, sore throat, rhinorrhea, musculoskeletal pain, vomiting, diarrhea, anosmia, neurologic decline; AND report that testing for infection (e.g. respiratory viral panel, SARS15 COV-2 testing) is clinically indicated based on evaluation by a healthc
