She has a history of recurrent generalized seizures, diffuse muscular weakness, and multiple episodes of transient left-sided paresis. She has been hospitalized several times for severe lactic acidosis requiring intravenous fluid hydration. Her 10-year-old daughter also has seizures and muscle weakness. Her 7-year-old son has occasional muscle weakness and headaches but has never had a seizure. Pathologic examination of a biopsy specimen from the womans soleus muscle shows ragged-appearing muscle fibers. Genetic analysis of the patients son is most likely to show which of the following?? A: Silenced paternal gene copy, B: Heterogenous mitochondrial DNA, C: Mutation in DNA repair gene, D: Genetically distinct cell lines, E: Altered allele on the X chromosome,  <response>: This is a question about identifying the most likely genetic abnormality in a patient with symptoms suggestive of a mitochondrial disorder. The key clues are recurrent seizures, muscle weakness, lactic acidosis, and ragged muscle fibers on biopsy in the patient and her daughter. This pattern indicates a maternally inherited mitochondrial disorder. The sons milder symptoms suggest he may have a lower level of abnormal mitochondrial DNA heteroplasmy. Therefore, the most likely genetic finding in the son would be heterogenous mitochondrial DNA, with a mixture of normal and abnormal mitochondrial DNA inherited from the mother.B: Heterogenous mitochondrial DNA
