She had a past history of asymptomatic methylmalonic acidemia but had been lost to follow\u2010up since the age of 15 years. Biochemical evaluation revealed combined methylmalonic acidemia and hyperhomocysteinemia. Complementation analysis confirmed cblC deficiency. One copy of the most common mutations in the MMACHC gene, c.271dupA, was identified. The women was treated from 15 weeks of gestation with a low protein diet (64 g\/day) (1.1 g \/kg of weight\/day), L\u2010carnitine (1 g per os 3 times daily to 3 g per os 3 times daily in the third trimester), aspirin (salicylic acid) 80 mg per day, folic acid 5 mg per day, and hydroxocobalamin 1 mg intramuscular every week to two times per week in the third trimester.
