Optimization of the Y831C mutation detection in human DNA polymerase gamma by allelic discrimination assay

Acta Biochim Pol. 2006;53(3):591-5. Epub 2006 Aug 23.


Many well-defined mutations in the gene for the catalytic subunit of polymerase gamma (POLG1) have been found to be associated with disease, whereas the status of several mutations remains unresolved due to the conflicting reports on their frequencies in populations of healthy individuals. Here, we have developed a highly sensitive, real-time allelic discrimination assay enabling detection of the Y831C mutation in the POLG1 gene. The Y831C mutation is present in the Polish population at a frequency of 2.25%. The new assay is well suited to both extensive population studies and molecular diagnostics of POLG1.
