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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 16, 2024The c.3377A>G (p.K1126R) alteration is located in exon 20 (coding exon 19) of the REV1 gene. This alteration results from a A to G substitution at nucleotide position 3377, causing the lysine (K) at amino acid position 1126 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
