January 26, 2021 updated by: Centre Hospitalier Universitaire de Nīmes

Research of Thymix Dysgenesis in Prenatal Examination of Deletion 22q11 Syndrome

22q11.2 microdeletion seems the prenatally under-diagnosed . Indeed , there is a mismatch between the series on the heart rate of 22q11.2 antenatal 84% against 30% in the adult series despite a perinatal mortality of 16% suggesting opportunities for improvement in the prenatal diagnosis of fetus with a microdeletion 22q11.2 , especially without heart disease
