Summaries for Combined Oxidative Phosphorylation Deficiency 16

NIH Rare Diseases : 52 Combined oxidative phosphorylation deficiency 16 , also know as infantile hypertrophic cardiomyopathy , is characterized by decreased levels of mitochondrial complexes . The symptoms and signs described include an enlarged heart muscle (hypertrophic cardiomyopathy ) and fatty liver (hepatic steatosis), as well as eye problems, headache, paralysis of one side of the body, Leigh-like lesions on brain magnetic resonance imaging (MRI), kidney insufficiency and neurological disease. It is caused by mutations in the MRPL44 gene , which results in mitochondrial dysfunction. The cases described seem to be inherited in an autosomal recessive pattern. Treatment is supportive.

MalaCards based summary : Combined Oxidative Phosphorylation Deficiency 16, is also known as coxpd16. An important gene associated with Combined Oxidative Phosphorylation Deficiency 16 is MRPL44 (Mitochondrial Ribosomal Protein L44). Affiliated tissues include liver, heart and eye, and related phenotypes are hypertrophic cardiomyopathy and elevated hepatic transaminase

Disease Ontology : 12 A combined oxidative phosphorylation deficiency that has material basis in homozygous or compund heterozygous mutation in MRPL44 on chromosome 2q36.1.

UniProtKB/Swiss-Prot : 73 Combined oxidative phosphorylation deficiency 16: An autosomal recessive, mitochondrial disorder characterized by hypertrophic cardiomyopathy, liver steatosis, and decreased levels of mitochondrial complexes I and IV in heart and skeletal muscle.
