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 GeneticsDec 13, 2021The c.2720C>A (p.A907D) alteration is located in exon 17 (coding exon 16) of the REV1 gene. This alteration results from a C to A substitution at nucleotide position 2720, causing the alanine (A) at amino acid position 907 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
