NCIt definition : Any homology-dependent DNA strand exchange that occurs between sister chromatids in
mitotic cells. This process is involved in creating combinations of genes that may
be unique from the parent duplexes. Disruptions in this process may result in inviability,
premature aging and predisposition to a broad variety of cancers.;
NCIt note : The autosomal recessive disorder Bloom Syndrome is closely associated with elevated
mitotic sister chromatid exchange.;
