Genes affected
NGLY1 (HGNC:17646): (N-glycanase 1) This gene encodes an enzyme that catalyzes hydrolysis of an N(4)-(acetyl-beta-D-glucosaminyl) asparagine residue to N-acetyl-beta-D-glucosaminylamine and a peptide containing an aspartate residue. The encoded enzyme may play a role in the proteasome-mediated degradation of misfolded glycoproteins. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Feb 2009]

Congenital disorder of deglycosylation Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeJul 14, 2022This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 96 of the NGLY1 protein (p.Glu96Lys). This variant is present in population databases (rs777476251, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with NGLY1-related conditions. ClinVar contains an entry for this variant (Variation ID: 541258). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
