Summaries for Mitochondrial Complex I Deficiency Due to Acad9 Deficiency

UniProtKB/Swiss-Prot : 75 Acyl-CoA dehydrogenase family, member 9, deficiency: An autosomal recessive metabolic disorder associated with mitochondrial complex I deficiency, resulting in multisystemic and variable manifestations. Clinical features include infantile onset of acute metabolic acidosis, Reye-like episodes (brain edema and vomiting that may rapidly progress to seizures, coma and death), exercise intolerance, hypertrophic cardiomyopathy, liver failure, muscle weakness, and neurologic dysfunction.

MalaCards based summary : Mitochondrial Complex I Deficiency Due to Acad9 Deficiency, also known as acad9 deficiency, is related to mitochondrial encephalomyopathy, and has symptoms including muscle weakness An important gene associated with Mitochondrial Complex I Deficiency Due to Acad9 Deficiency is ACAD9 (Acyl-CoA Dehydrogenase Family Member 9). Affiliated tissues include liver, heart and brain, and related phenotypes are failure to thrive and sudden cardiac death

Genetics Home Reference : 25 ACAD9 deficiency is a condition that varies in severity and can cause muscle weakness (myopathy), heart problems, and intellectual disability. Nearly all affected individuals have a buildup of a chemical called lactic acid in the body (lactic acidosis). Additional signs and symptoms that affect other body systems occur in rare cases.

OMIM : 57 ACAD9 deficiency is an autosomal recessive multisystem disorder characterized by infantile onset of acute metabolic acidosis, hypertrophic cardiomyopathy, and muscle weakness associated with a deficiency of mitochondrial complex I activity in muscle, liver, and fibroblasts (summary by Haack et al., 2010). For a general description and a discussion of genetic heterogeneity of mitochondrial complex I deficiency, see 252010. (611126)
