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.415G>T (p.A139S) alteration is located in exon 1 (coding exon 1) of the SMUG1 gene. This alteration results from a G to T substitution at nucleotide position 415, causing the alanine (A) at amino acid position 139 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
