Genes affected

SMUG1 (HGNC:17148): (single-strand-selective monofunctional uracil-DNA glycosylase 1) This gene encodes a protein that participates in base excision repair by removing uracil from single- and double-stranded DNA. Many alternatively spliced transcript variants exist for this gene; the full-length nature is known for some but not all of the variants. [provided by RefSeq, Aug 2011]

The c.23G>A (p.G8E) alteration is located in exon 1 (coding exon 1) of the SMUG1 gene. This alteration results from a G to A substitution at nucleotide position 23, causing the glycine (G) at amino acid position 8 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
