Is Medium-chain acyl-coenzyme A dehydrogenase deficiency inherited ?
How is medium-chain acyl-coenzyme A dehydrogenase (MCAD) deficiency inherited? Medium-chain acyl-coenzyme A dehydrogenase deficiency (MCADD) is inherited in an autosomal recessive manner. This means that both copies of the responsible gene in each cell must have mutations for a person to be affected. Usually, the parents of a person with an autosomal recessive condition each have one mutated copy of the gene and are referred to as carriers. Carriers typically do not have any signs or symptoms of the condition. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) chance to be affected, a 50% (1 in 2) chance to be a carrier like each parent, and a 25% chance to be unaffected and not be a carrier.
