gene: COQ8A was added to Rhabdomyolysis and metabolic muscle disorders. Sources: Expert list,Expert Review
Mode of inheritance for gene: COQ8A was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: COQ8A were set to 26818466; 22036850; 18319074; 18319072; 32337771
Phenotypes for gene: COQ8A were set to Coenzyme Q10 deficiency, primary, 4, OMIM:612016
Review for gene: COQ8A was set to GREEN
Added comment: Coenzyme Q10 deficiency is a heterogeneous disease with multple causal genes, typically inherited in an autosomal recessive pattern (including COQ8A/ADCK3). Variants in COQ8A cause a juvenile-onset cerebellar ataxia with primary CoQ10 deficiency. Some patients display muscle weakness and exercise intolerance (typically with elevated serum lactate) early in the course of disease but it is not clear if this is associated with rhabdomyolysis although this may be plausible following physical exertion.

PMID:32337771 reported a cohort of 59 individuals with 44 pathogenic COQ8A variants and presenting with variable multisystemic, early-onset cerebellar ataxia, with complicating features ranging from epilepsy (32%) and cognitive impairment (49%) to exercise intolerance (25%) and hyperkinetic movement disorders (41%), including dystonia and myoclonus.
