Summaries for Coenzyme Q10 Deficiency, Primary, 7

OMIM : 57 Primary coenzyme Q10 deficiency-7 is an autosomal recessive disorder resulting from mitochondrial dysfunction. Most patients have onset of severe cardiac or neurologic symptoms soon after birth, usually resulting in death. Rare patients may have later onset with a more protracted course. Tissue samples from affected individuals show decreased levels of coenzyme Q10 (CoQ10) (summary by Brea-Calvo et al., 2015). For a general phenotypic description and a discussion of genetic heterogeneity of primary coenzyme Q10 deficiency, see COQ10D1 (607426). (616276)

MalaCards based summary : Coenzyme Q10 Deficiency, Primary, 7, is also known as coq10d7. An important gene associated with Coenzyme Q10 Deficiency, Primary, 7 is COQ4 (Coenzyme Q4). Affiliated tissues include skeletal muscle, and related phenotypes are seizures and neonatal hypotonia

UniProtKB/Swiss-Prot : 75 Coenzyme Q10 deficiency, primary, 7: An autosomal recessive disorder resulting from mitochondrial dysfunction and characterized by decreased levels of coenzyme Q10, and severe cardiac or neurologic symptoms soon after birth, usually resulting in death.
