Coenzyme Q10 Deficiency, Primary, 1; Coq10d1

Description

Primary CoQ10 deficiency is a rare, clinically heterogeneous autosomal recessive disorder caused by mutation in any of the genes encoding proteins directly involved in the synthesis of coenzyme Q (review by Quinzii and Hirano, 2011). Coenzyme Q10 (CoQ10), or ubiquinone, is a mobile lipophilic electron carrier critical for electron transfer by the mitochondrial inner membrane respiratory chain (Duncan et al., 2009).The disorder has been associated with 5 major phenotypes, but the molecular basis has not been determined in most patients with the disorder and there are no clear genotype/phenotype correlations. The phenotypes include an encephalomyopathic form with seizures and ataxia (Ogasahara et al., 1989); a multisystem infantile form with encephalopathy, cardiomyopathy and renal failure (Rotig et al., 2000); a predominantly cerebellar form with ataxia and cerebellar atrophy (Lamperti et al., 2003); Leigh syndrome with growth retardation (van Maldergem et al., 2002); and an isolated myopathic form (Lalani et al., 2005). The correct diagnosis is important because some patients may show a favorable response to CoQ10 treatment. Genetic Heterogeneity of Primary Coenzyme Q10 DeficiencySee also COQ10D2 (OMIM ), caused by mutation in the PDSS1 gene (OMIM ) on chromosome 10p12; COQ10D3 (OMIM ), caused by mutation in the PDSS2 gene (OMIM ) on chromosome 6q21; COQ10D4 (OMIM ), caused by mutation in the COQ8 gene (ADCK3 ) on chromosome 1q42; COQ10D5 (OMIM ), caused by mutation in the COQ9 gene (OMIM ) on chromosome 16q21; COQ10D6 (OMIM ), caused by mutation in the COQ6 gene (OMIM ) on chromosome 14q24; COQ10D7 (OMIM ), caused by mutation in the COQ4 gene (OMIM ) on chromosome 9q34; and COQ10D8 (OMIM ), caused by mutation in the COQ7 gene (OMIM ) on chromosome 16p13.Secondary CoQ10 deficiency has been reported in association with glutaric aciduria type IIC (MADD ), caused by mutation in the ETFDH gene (OMIM ) on chromosome 4q, and with ataxia-oculomotor apraxia syndrome-1 (AOA1 ), caused by mutation in the APTX gene (OMIM ) on chromosome 9p13.
