NGLY1 deficiency-A rare congenital disorder of deglycosylation.

ABSTRACT: Pathogenic variants in the NGLY1 gene are associated with a Congenital Disorder of Deglycosylation (CDDG) characterized by delays in reaching developmental milestones, complex hyperkinetic movement disorder, transient elevation of transaminases, and alacrima or hypolacrima. To date, only few cases of NGLY1 deficiency have been identified and reported in the literature. This report highlights a first child of non-consanguineous parents with no relevant family history who presented with hypotonia and poor weight gain since birth.
