After maternal exposure to mycophenolate in pregnancy a high number of fetal losses and specific pattern birth defects consisting microtia, cleft lip, other anomalies have been reported. However, so far, prospective data on outcome allowing quantitative risk assessment are missing. We report 57 prospectively ascertained pregnancies after therapy with (mycophenolate mofetil or sodium) identified by European Teratology Information Services (ETIS) through their consultation process.
