Genes affected
NDUFB8 (HGNC:7703): (NADH:ubiquinone oxidoreductase subunit B8) Involved in mitochondrial respiratory chain complex I assembly. Located in endoplasmic reticulum and mitochondrion. Part of mitochondrial respiratory chain complex I. Implicated in nuclear type mitochondrial complex I deficiency 32. Biomarker of Alzheimer's disease and Parkinson's disease. [provided by Alliance of Genome Resources, Apr 2022]
HIF1AN (HGNC:17113): (hypoxia inducible factor 1 subunit alpha inhibitor) Enables several functions, including 2-oxoglutarate-dependent dioxygenase activity; NF-kappaB binding activity; and transition metal ion binding activity. Involved in several processes, including negative regulation of Notch signaling pathway; negative regulation of transcription from RNA polymerase II promoter in response to hypoxia; and protein hydroxylation. Located in cytosol; nucleoplasm; and perinuclear region of cytoplasm. Colocalizes with nucleus. [provided by Alliance of Genome Resources, Apr 2022]
