Genes affected

RAD18 (HGNC:18278): (RAD18 E3 ubiquitin protein ligase) The protein encoded by this gene is highly similar to S. cerevisiae DNA damage repair protein Rad18. Yeast Rad18 functions through its interaction with Rad6, which is an ubiquitin-conjugating enzyme required for post-replication repair of damaged DNA. Similar to its yeast counterpart, this protein is able to interact with the human homolog of yeast Rad6 protein through a conserved ring-finger motif. Mutation of this motif results in defective replication of UV-damaged DNA and hypersensitivity to multiple mutagens. [provided by RefSeq, Jul 2008]

Nov 14, 2023

The c.940C>G (p.L314V) alteration is located in exon 8 (coding exon 8) of the RAD18 gene. This alteration results from a C to G substitution at nucleotide position 940, causing the leucine (L) at amino acid position 314 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
