Genes affected

RFC1 (HGNC:9969): (replication factor C subunit 1) This gene encodes the large subunit of replication factor C, a five subunit DNA polymerase accessory protein, which is a DNA-dependent ATPase required for eukaryotic DNA replication and repair. The large subunit acts as an activator of DNA polymerases, binds to the 3' end of primers, and promotes coordinated synthesis of both strands. It may also have a role in telomere stability. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene. [provided by RefSeq, Mar 2011]

The c.3385C>T (p.P1129S) alteration is located in exon 25 (coding exon 25) of the RFC1 gene. This alteration results from a C to T substitution at nucleotide position 3385, causing the proline (P) at amino acid position 1129 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
