Summaries for Combined Oxidative Phosphorylation Deficiency 2

UniProtKB/Swiss-Prot : 73 Combined oxidative phosphorylation deficiency 2: A mitochondrial disease resulting in fatal neonatal metabolic acidosis with agenesis of the corpus callosum.

MalaCards based summary : Combined Oxidative Phosphorylation Deficiency 2, also known as coxpd2, is related to combined oxidative phosphorylation deficiency and neurodevelopmental disorder with microcephaly, seizures, and cortical atrophy. An important gene associated with Combined Oxidative Phosphorylation Deficiency 2 is MRPS16 (Mitochondrial Ribosomal Protein S16), and among its related pathways/superpathways is tRNA Aminoacylation. Affiliated tissues include skin, liver and testes, and related phenotypes are abnormal facial shape and neonatal hypotonia

Disease Ontology : 12 A combined oxidative phosphorylation deficiency that has material basis in homozygous or compound heterozygous mutation in MRPS16 on chromosome 10q22.2.
