SDHAF3 (Succinate Dehydrogenase Complex Assembly Factor 3): SDHAF3 is a gene involved in assembling the succinate dehydrogenase complex, a key component of the mitochondrial electron transport chain. This protein helps maintain the proper function of the complex, supporting efficient energy production. Mutations in SDHAF3 can impair mitochondrial activity and contribute to mitochondrial disorders, highlighting its importance in cellular health.
