Congenital disorders of Glycosylation (CDG) are increasingly emerging as a major underlying etiology for patients with complex neurogenetic malformations and dysmorphic features. We describe a newborn female with arthrogryposis multiplex due to fetal akinesia secondary to CDG-DPAGT1. Pregnancy was complicated by reduced fetal movements. At birth, the patient was evaluated for intrauterine growth restriction, bilateral cataracts, and multiple joint contractures. She had markedly reduced spontaneous movements,
hypotonia
, weak cry, and poor suck. She had ventilator-dependent central respiratory depression. Brain MRI showed delayed myelination and an incomplete cerebellar vermis. Transferrin isoelectric focusing was suggestive of a type I congenital disorder of glycosylation. Sequencing revealed a homozygous missense mutation in
dolichyl-phosphate N-acetylglucosaminephosphotransferase
(DPAGT1), exon 3, p.Leu118Val, consistent with DPAGT1-CDG. There have been seventeen previously reported cases of DPAGT1-CDG, including two similar cases with multiple contractures. This case highlights the importance of considering congenital disorders of glycosylation in the differential diagnosis for arthrogryposis.
