Medium chain acyl-CoA dehydrogenase (MCAD) deficiency is an autosomal recessive fatty acid oxidation disorder, with an incidence rate of up to 1 in 12 000. Early diagnosis and treatment might prevent sudden death or long-term disability.
Bottom line
Parents-to-be should be informed, preferably in the prenatal period, of newborn screening for MCAD deficiency and other disorders. The panel of disorders screened for during that time varies by province—physicians should familiarize themselves with their local newborn screening programs.
