Genes affected

RFC3 (HGNC:9971): (replication factor C subunit 3) The elongation of primed DNA templates by DNA polymerase delta and DNA polymerase epsilon requires the accessory proteins proliferating cell nuclear antigen (PCNA) and replication factor C (RFC). RFC, also named activator 1, is a protein complex consisting of five distinct subunits of 140, 40, 38, 37, and 36 kDa. This gene encodes the 38 kDa subunit. This subunit is essential for the interaction between the 140 kDa subunit and the core complex that consists of the 36, 37, and 40 kDa subunits. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Jul 2008]

Ambry Genetics

Feb 12, 2024

The c.854G>T (p.C285F) alteration is located in exon 8 (coding exon 8) of the RFC3 gene. This alteration results from a G to T substitution at nucleotide position 854, causing the cysteine (C) at amino acid position 285 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
