Genes affected

REV1 (HGNC:14060): (REV1 DNA directed polymerase) This gene encodes a protein with similarity to the S. cerevisiae mutagenesis protein Rev1. The Rev1 proteins contain a BRCT domain, which is important in protein-protein interactions. A suggested role for the human Rev1-like protein is as a scaffold that recruits DNA polymerases involved in translesion synthesis (TLS) of damaged DNA. [provided by RefSeq, Mar 2016]

REV1 links:

EIF5B (HGNC:30793): (eukaryotic translation initiation factor 5B) Accurate initiation of translation in eukaryotes is complex and requires many factors, some of which are composed of multiple subunits. The process is simpler in prokaryotes which have only three initiation factors (IF1, IF2, IF3). Two of these factors are conserved in eukaryotes: the homolog of IF1 is eIF1A and the homolog of IF2 is eIF5B. This gene encodes eIF5B. Factors eIF1A and eIF5B interact on the ribosome along with other initiation factors and GTP to position the initiation methionine tRNA on the start codon of the mRNA so that translation initiates accurately.

Ambry Genetics

Nov 18, 2022

The c.3664G>C (p.E1222Q) alteration is located in exon 23 (coding exon 22) of the REV1 gene. This alteration results from a G to C substitution at nucleotide position 3664, causing the glutamic acid (E) at amino acid position 1222 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
