Rare MGRN1 gene variant tied to fetal heart malformations

The Human Genetics Research Group of the University of Tartu Faculty of Medicine has identified a gene whose defect may cause congenital heart malformations in the fetus. The MGRN1 gene has not previously been associated with early human development or with any disease. The discovery will help doctors better recognize similar cases in the future and improve the counseling and treatment offered to affected families.
