Submissions by phenotype
not provided Uncertain:2
Not observed at a significant frequency in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; Has not been previously published as pathogenic or benign to our knowledge -

Congenital disorder of deglycosylation Uncertain:1
This sequence change replaces aspartic acid, which is acidic and polar, with valine, which is neutral and non-polar, at codon 412 of the NGLY1 protein (p.Asp412Val). This variant is present in population databases (rs778513258, gnomAD 0.005%). 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: 572271). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt NGLY1 protein function with a negative predictive value of 80%. 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. -
Inborn genetic diseases Uncertain:1
The c.1235A>T (p.D412V) alteration is located in exon 8 (coding exon 8) of the NGLY1 gene. This alteration results from a A to T substitution at nucleotide position 1235, causing the aspartic acid (D) at amino acid position 412 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
