Your QuestionMy sister's daughter (my niece) recently had a baby and he was diagnosed with medium-chain acyl-coenzyme A dehydrogenase (MCAD) deficiency. If this condition is traced back to my sister, is it important for me and/or my children (ages 8 and 11) to be tested?

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.
Your family may benefit from consulting with a genetics professional who can help to determine who may be at risk for medium-chain acyl-coenzyme A dehydrogenase (MCAD) deficiency and who warrants further testing. Genetics clinics are a source of information for individuals and families regarding genetic diagnosis, natural history, treatment, mode of inheritance, and genetic risks to other family members.
