Methimazole embryofetopathy
MONDO:0016017Methimazole embryopathy is a teratogenic embryofetopathy that results from maternal exposition to methimazole (MMI; or the parent compound carbimazole) in the first trimester of pregnancy. MMI is an antithyroid thionamide drug used for the treatment of Graves' disease. In the infant, MMI may result in choanal atresia, esophageal atresia, omphalocele, omphalomesenteric duct anomalies, congenital heart disease (such as ventricular septal defect), renal system malformations and aplasia cutis. Additional features that may be observed include facial dysmorphism (short upslanting palpebral fissures, a broad nasal bridge with a small nose and a broad forehead) and athelia/hypothelia.
Also known as: MMI/CMZ embryofetopathy, MMI/CMZ embryopathy, Methimazole/carbimazole embryofetopathy, Methimazole/carbimazole embryopathy, methimazole embryofetopathy, Methimazole antenatal exposure, fetal methimazole syndrome, foetal methimazole syndrome

Gene sequencing uncovers mysterious fetal malformations
Knowledge-focused CompletedThis study tested whether a powerful DNA test called high-throughput exome sequencing can find genetic causes of multiple birth defects in fetuses when standard exams fail. Researchers studied 100 fetuses with at least two malformations and no prior diagnosis. They compared the n…

Speedy gene test aims to give answers on birth defects in just 7 days
Knowledge-focused CompletedThis study tested whether a fast type of genetic test called rapid genome sequencing can find the cause of birth defects seen on ultrasound more quickly than current methods. Researchers included 184 pregnancies with certain ultrasound findings. The goal was to see if results cou…
