Pathology & Biotechi

Involvement in diseasei

UQCC3 mutations are a cause of mitochondrial complex III deficiency, a disorder of the mitochondrial respiratory chain resulting in a highly variable phenotype depending on which tissues are affected. UQCC3-related mitochondrial complex III deficiency results in lactic acidosis, hypoglycemia, hypotonia and delayed psychomotor development. Patients do not manifest dysmorphic features.1 Publication
