Genes affected
MOGS (HGNC:24862): (mannosyl-oligosaccharide glucosidase) This gene encodes the first enzyme in the N-linked oligosaccharide processing pathway. The enzyme cleaves the distal alpha-1,2-linked glucose residue from the Glc(3)-Man(9)-GlcNAc(2) oligosaccharide precursor. This protein is located in the lumen of the endoplasmic reticulum. Defects in this gene are a cause of type IIb congenital disorder of glycosylation (CDGIIb). Two transcript variants encoding different isoforms have been found for this gene.

Inborn genetic diseases Uncertain:1
Jan 03, 2024
Ambry Genetics
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.1072A>T (p.T358S) alteration is located in exon 4 (coding exon 4) of the MOGS gene. This alteration results from a A to T substitution at nucleotide position 1072, causing the threonine (T) at amino acid position 358 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

MOGS-congenital disorder of glycosylation Uncertain:1

Labcorp Genetics (formerly Invitae), Labcorp
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces threonine, which is neutral and polar, with serine, which is neutral and polar, at codon 358 of the MOGS protein (p.Thr358Ser). This variant is present in population databases (rs371692461, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with MOGS-related conditions. ClinVar contains an entry for this variant (Variation ID: 573840). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The serine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
