Genes affected
EOGT (HGNC:28526): (EGF domain specific O-linked N-acetylglucosamine transferase) This gene encodes an enzyme that acts in the lumen of the endoplasmic reticulum to catalyze the transfer of N-acetylglucosamine to serine or threonine residues of extracellular-targeted proteins. This enzyme modifies proteins containing eukaryotic growth factor (EGF)-like domains, including the Notch receptor, thereby regulating developmental signalling. Mutations in this gene have been observed in individuals with Adams-Oliver syndrome 4. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2015]

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

This sequence change creates a premature translational stop signal (p.His27Alafs*46) in the EOGT gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in EOGT are known to be pathogenic (PMID: 23522784, 23860037). This variant is present in population databases (rs771160630, gnomAD 0.02%). This premature translational stop signal has been observed in individual(s) with Adams-Oliver syndrome (PMID: 29924900). ClinVar contains an entry for this variant (Variation ID: 523593). For these reasons, this variant has been classified as Pathogenic. -
