Genes affected
POGLUT1 (HGNC:22954): (protein O-glucosyltransferase 1) This gene encodes a protein with both O-glucosyltransferase and O-xylosyltransferase activity which localizes to the lumen of the endoplasmic reticulum. This protein has a carboxy-terminal KTEL motif which is predicted to function as an endoplasmic reticulum retention signal. This gene is an essential regulator of Notch signalling and likely plays a role in cell fate and tissue formation during development. It may also play a role in the pathogenesis of leukemia. Mutations in this gene have been associated with the autosomal dominant genodermatosis Dowling-Degos disease 4. Alternative splicing results in multiple transcript variants.

This sequence change creates a premature translational stop signal (p.Arg218*) in the POGLUT1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in POGLUT1 are known to be pathogenic (PMID: 24387993). This variant is present in population databases (rs587777294, gnomAD 0.006%). This premature translational stop signal has been observed in individuals with Dowling-Degos disease (PMID: 24387993, 27479915). ClinVar contains an entry for this variant (Variation ID: 126529). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
