DPAGT1: Recurrent Fetal Death

Congenital disorders of glycosylation (CDG) are a series of relatively uncommon genetic disorders, and variants in the dolichyl-phosphate N-acetylglucosamine-1-phosphotransferase (DPAGT1) gene can cause DPAGT1-CDG, which is characterized by multisystem abnormalities: failure to thrive, psychomotor retardation, seizures, etc. PATIENTS: Two fetuses in a nonconsanguineous family recurrently presented with irregular skull morphology, micrognathia, adduction and supination by prenatal ultrasound. They were finally found dead in utero. Pedigree whole exome sequencing revealed novel compound heterozygous variants in the DPAGT1 gene. We also reviewed 11 previous reports associated with DPAGT1-CDG.
