Genes affected
ACADM (HGNC:89): (acyl-CoA dehydrogenase medium chain) This gene encodes the medium-chain specific (C4 to C12 straight chain) acyl-Coenzyme A dehydrogenase. The homotetramer enzyme catalyzes the initial step of the mitochondrial fatty acid beta-oxidation pathway. Defects in this gene cause medium-chain acyl-CoA dehydrogenase deficiency, a disease characterized by hepatic dysfunction, fasting hypoglycemia, and encephalopathy, which can result in infantile death. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Uncertain significance, criteria provided, single submitterclinical testingGeneDxJun 29, 2017The c.-17 C>G variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The c.-17 C>G variant is observed in 5/10186 (0.05%) alleles from individuals of African background in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). This nucleotide substitution occurs at a position that is not conserved. Several in-silico splice prediction models predict that c.-17 C>G does not affect normal gene splicing. However, in the absence of RNA/functional studies, the actual effect of this sequence change in this individual is unknown. In summary, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant. -
