The product of RAD51C gene is essential
for the homologous recombination (HR) pathway of DNA repair. It is involved in
the homologous recombination repair (HRR) pathway of double-stranded DNA breaks
arising during DNA replication or induced by
Defects in RAD51C are the cause of
breast-ovarian cancer familial type 3 (BROVCA3) [for BROVCA1, see BRCA1, for
BROVCA2, see BRCA2]. It is a condition associated with familial predisposition
to cancer of the breast and ovaries. Characteristic features in affected
families are an early age of onset of breast cancer (often before age 50),
increased chance of bilateral cancers (cancer that develop in both breasts, or
both ovaries, independently), frequent occurrence of breast cancer among men,
increased incidence of tumors of other specific organs, such as the prostate.
Defects in RAD51C are the cause of Fanconi
anemia complementation group O (FANCO). See Fanconi Anemia genes.
