Summaries for Combined Oxidative Phosphorylation Deficiency 28

OMIM : 58 Combined oxidative phosphorylation deficiency-28 (COXPD28) is a complex autosomal recessive multisystem disorder associated with mitochondrial dysfunction. The phenotype is variable, but includes episodic metabolic decompensation beginning in infancy that can result in mild muscle weakness, cardiorespiratory insufficiency, developmental delay, or even death. Biochemical studies of patient tissues show variable mitochondrial defects, including decreased activities of respiratory chain enzymes (summary by Kishita et al., 2015). For a discussion of genetic heterogeneity of combined oxidative phosphorylation deficiency, see COXPD1 (609060). (616794)

MalaCards based summary : Combined Oxidative Phosphorylation Deficiency 28, is also known as coxpd28. An important gene associated with Combined Oxidative Phosphorylation Deficiency 28 is SLC25A26 (Solute Carrier Family 25 Member 26). Affiliated tissues include heart and skeletal muscle, and related phenotypes are generalized hypotonia and increased serum pyruvate

UniProtKB/Swiss-Prot : 76 Combined oxidative phosphorylation deficiency 28: An autosomal recessive mitochondrial disorder characterized by decreased activities of respiratory chain enzymes, and variable clinical manifestations. Clinical features include episodic metabolic decompensation beginning in infancy, mild muscle weakness, cardiorespiratory insufficiency, developmental delay, or even death.
