Succinate dehydrogenase complex subunit D pseudogene 4 (SDHDP4)

SDHDP4 (succinate dehydrogenase complex subunit D pseudogene 4) is a human pseudogene related to the succinate dehydrogenase complex subunit D (SDHD). Unlike the functional SDHD, which is a component of mitochondrial complex II and involved in electron transport and cellular energy production[4], SDHDP4 does not encode a functional protein and has no direct role in cellular metabolism, disease, or pharmacology[3]. It is included in genetic databases for reference purposes and is not considered a therapeutic target. If a user is searching for the functional **succinate dehydrogenase complex subunit D (SDHD)**, not SDHDP4, information should instead be drawn from SDHD, an enzyme implicated in mitochondrial function and certain disease states[4].
