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.

The c.65A>G (p.Q22R) alteration is located in exon 1 (coding exon 1) of the POGLUT1 gene. This alteration results from a A to G substitution at nucleotide position 65, causing the glutamine (Q) at amino acid position 22 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
