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.Trp4*) 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 (rs587777293, gnomAD 0.001%). This premature translational stop signal has been observed in individual(s) with Dowling-Degos disease (PMID: 24387993). ClinVar contains an entry for this variant (Variation ID: 126528). For these reasons, this variant has been classified as Pathogenic.
