Summaries for Combined Oxidative Phosphorylation Deficiency 18

OMIM : 56 Combined oxidative phosphorylation deficiency-18 is an autosomal recessive disorder of mitochondrial function characterized by intrauterine growth retardation, hypotonia, visual impairment, speech delay, and lactic acidosis associated with decreased mitochondrial respiratory chain activity. Affected patients may also show hematologic abnormalities, mainly macrocytic anemia (summary by Hildick-Smith et al., 2013). For a discussion of genetic heterogeneity of combined oxidative phosphorylation deficiency, see COXPD1 (609060). (615578)

MalaCards based summary : Combined Oxidative Phosphorylation Deficiency 18, is also known as coxpd18, and has symptoms including tremor An important gene associated with Combined Oxidative Phosphorylation Deficiency 18 is SFXN4 (Sideroflexin 4). Affiliated tissues include skeletal muscle, neutrophil and eye, and related phenotypes are macrocytic anemia and tremor

Disease Ontology : 12 A combined oxidative phosphorylation deficiency characterized by intrauterine growth retardation, hypotonia, visual impairment, speech delay, and lactic acidosis that has material basis in homozygous or compound heterozygous mutation in SFXN4 on chromosome 10q26.11.

UniProtKB/Swiss-Prot : 73 Combined oxidative phosphorylation deficiency 18: An autosomal recessive disorder of mitochondrial dysfunction characterized by intrauterine growth retardation, hypotonia, visual impairment, speech delay, and lactic acidosis associated with decreased mitochondrial respiratory chain activity. Affected patients may also show hematologic abnormalities, mainly macrocytic anemia.
