NIH Rare Diseases:44 Mitochondrial complex iii deficiency is one of several conditions caused by dysfunction of mitochondria, which are specialized compartments in cells that generate more than 90% of the energy required by the body. it is a severe, multisystem disorder that includes features such as lactic acidosis, hypotonia, hypoglycemia, failure to thrive, encephalopathy, and delayed psychomotor development. involvement of internal organs, including liver disease and renal tubulopathy, may also occur. symptoms typically begin at birth. many affected individuals die in early childhood, but some have survived longer. it is generally caused by mutations in nuclear dna in the bcs1l, uqcrb and uqcrq genes and inherited in an autosomal recessive manner. however, it may also be caused by mutations in mitochondrial dna in the mtcyb gene, which is passed down maternally or occurs sporadically and may result in a milder form of the condition. treatment generally focuses on alleviating symptoms and/or slowing down the progression of the disease, and effectiveness can vary among individuals. last updated: 4/4/2011

MalaCards: Mitochondrial Complex Iii Deficiency, also known as complex 3 mitochondrial respiratory chain deficiency, is related to mitochondrial complex iii deficiency, nuclear type 1 and mitochondrial complex iii deficiency, nuclear type 6. An important gene associated with Mitochondrial Complex Iii Deficiency is BCS1L (BC1 (ubiquinol-cytochrome c reductase) synthesis-like), and among its related pathways are Mitochondrial Protein Import and Metabolism. The compounds Ubiquinone Q1 and QH2 have been mentioned in the context of this disorder. Affiliated tissues include liver.
