Summaries for Combined Oxidative Phosphorylation Deficiency 35

OMIM : 58 COXPD35 is an autosomal recessive disorder characterized mainly by global developmental delay with intellectual disability, microcephaly, and early-onset myoclonic and other types of seizures. Affected individuals have variable deficiencies of mitochondrial respiratory enzyme complexes resulting from a defect in mitochondrial metabolism (summary by Kernohan et al., 2017). For a discussion of genetic heterogeneity of combined oxidative phosphorylation deficiency, see COXPD1 (609060). (617873)

MalaCards based summary : Combined Oxidative Phosphorylation Deficiency 35, is also known as coxpd35. An important gene associated with Combined Oxidative Phosphorylation Deficiency 35 is TRIT1 (TRNA Isopentenyltransferase 1). Related phenotypes are optic disc hypoplasia and intellectual disability

UniProtKB/Swiss-Prot : 76 Combined oxidative phosphorylation deficiency 35: An autosomal recessive disorder caused by defective mitochondrial metabolism and deficiencies of mitochondrial respiratory enzyme complexes. Clinical manifestations include global developmental delay, intellectual disability, microcephaly, and early-onset seizures.
